  Overrides:
    release in class BaseDirContext

### lookup

    public java.lang.Object lookup(java.lang.String name)
                            throws javax.naming.NamingException

  Retrieves the named object.
  Overrides:
    lookup in class BaseDirContext
  Parameters:
    `name` - the name of the object to look up
  Returns:
    the object bound to name
  Throws:
    javax.naming.NamingException - if a naming exception is encountered

### lookup

    public java.lang.Object lookup(javax.naming.Name name)
                            throws javax.naming.NamingException

  Retrieves the named object. If name is empty, returns a new instance of this context (which represents the same naming context as this context, but its environment may be modified independently and it may be accessed concurrently).
  Overrides:
    lookup in class BaseDirContext
  Parameters:
    `name` - the name of the object to look up
  Returns:
    the object bound to name
  Throws:

### unbind

    public void unbind(java.lang.String name)
                throws javax.naming.NamingException

  Unbinds the named object. Removes the terminal atomic name in name from the target context--that named by all but the terminal atomic part of name.

  This method is idempotent. It succeeds even if the terminal atomic name is not bound in the target context, but throws NameNotFoundException if any of the intermediate contexts do not exist.

  Overrides:
    unbind in class BaseDirContext
  Parameters:
    `name` - the name to bind; may not be empty
  Throws:
    NameNotFoundException - if an intermediate context does not exist
    javax.naming.NamingException - if a naming exception is encountered

### rename

    public void rename(java.lang.String oldName,
                       java.lang.String newName)
                throws javax.naming.NamingException

  Binds a new name to the object bound to an old name, and unbinds the old name. Both names are relative to this context. Any attributes associated with the old name become associated with the new name. Intermediate contexts of the old name are not changed.
  Overrides:
    rename in class BaseDirContext
  Parameters:
    `oldName` - the name of the existing binding; may not be empty
    `newName` - the name of the new binding; may not be empty
  Throws:
    javax.naming.NameAlreadyBoundException - if newName is already bound
    javax.naming.NamingException - if a naming exception is encountered

### list

    public javax.naming.NamingEnumeration list(java.lang.String name)
                                        throws javax.naming.NamingException

  Enumerates the names bound in the named context, along with the class names of objects bound to them. The contents of any subcontexts are not included.

  If a binding is added to or removed from this context, its effect on an enumeration previously returned is undefined.

  Overrides:
    list in class BaseDirContext
  Parameters:
    `name` - the name of the context to list
  Returns:
    an enumeration of the names and class names of the bindings in this context. Each element of the enumeration is of type NameClassPair.
  Throws:
    javax.naming.NamingException - if a naming exception is encountered

### list

    public javax.naming.NamingEnumeration list(javax.naming.Name name)
                                        throws javax.naming.NamingException

  Enumerates the names bound in the named context, along with the class names of objects bound to them. The contents of any subcontexts are not included.

  If a binding is added to or removed from this context, its effect on an enumeration previously returned is undefined.

  Overrides:
    list in class BaseDirContext
  Parameters:
    `name` - the name of the context to list
  Returns:
    an enumeration of the names and class names of the bindings in this context. Each element of the enumeration is of type NameClassPair.
  Throws:
    javax.naming.NamingException - if a naming exception is encountered

### listBindings

    public javax.naming.NamingEnumeration listBindings(java.lang.String name)
                                                throws javax.naming.NamingException

  Enumerates the names bound in the named context, along with the objects bound to them. The contents of any subcontexts are not included.

  If a binding is added to or removed from this context, its effect on an enumeration previously returned is undefined.

  Overrides:
    listBindings in class BaseDirContext
  Parameters:
    `name` - the name of the context to list
  Returns:
    an enumeration of the bindings in this context. Each element of the enumeration is of type Binding.
  Throws:
    javax.naming.NamingException - if a naming exception is encountered

### listBindings

    public javax.naming.NamingEnumeration listBindings(javax.naming.Name name)
                                                throws javax.naming.NamingException

  Enumerates the names bound in the named context, along with the objects bound to them. The contents of any subcontexts are not included.

  If a binding is added to or removed from this context, its effect on an enumeration previously returned is undefined.

  Overrides:
    listBindings in class BaseDirContext
  Parameters:
    `name` - the name of the context to list
  Returns:
    an enumeration of the bindings in this context. Each element of the enumeration is of type Binding.
  Throws:
    javax.naming.NamingException - if a naming exception is encountered

### destroySubcontext

    public void destroySubcontext(java.lang.String name)
                           throws javax.naming.NamingException

  Destroys the named context and removes it from the namespace. Any attributes associated with the name are also removed. Intermediate contexts are not destroyed.

  This method is idempotent. It succeeds even if the terminal atomic name is not bound in the target context, but throws NameNotFoundException if any of the intermediate contexts do not exist. In a federated naming system, a context from one naming system may be bound to a name in another. One can subsequently look up and perform operations on the foreign context using a composite name. However, an attempt destroy the context using this composite name will fail with NotContextException, because the foreign context is not a "subcontext" of the context in which it is bound. Instead, use unbind() to remove the binding of the foreign context. Destroying the foreign context requires that the destroySubcontext() be performed on a context from the foreign context's "native" naming system.

  Overrides:
    destroySubcontext in class BaseDirContext
  Parameters:
    `name` - the name of the context to be destroyed; may not be empty
  Throws:
    NameNotFoundException - if an intermediate context does not exist
    NotContextException - if the name is bound but does not name a context, or does not name a context of the appropriate type

### lookupLink

    public java.lang.Object lookupLink(java.lang.String name)
                                throws javax.naming.NamingException

  Retrieves the named object, following links except for the terminal atomic component of the name. If the object bound to name is not a link, returns the object itself.
  Overrides:
    lookupLink in class BaseDirContext
  Parameters:
    `name` - the name of the object to look up
  Returns:
    the object bound to name, not following the terminal link (if any).
  Throws:
    javax.naming.NamingException - if a naming exception is encountered

### getNameInNamespace

    public java.lang.String getNameInNamespace()
                                        throws javax.naming.NamingException

  Retrieves the full name of this context within its own namespace.

  Many naming services have a notion of a "full name" for objects in their respective namespaces. For example, an LDAP entry has a distinguished name, and a DNS record has a fully qualified name. This method allows the client application to retrieve this name. The string returned by this method is not a JNDI composite name and should not be passed directly to context methods. In naming systems for which the notion of full name does not make sense, OperationNotSupportedException is thrown.

  Overrides:
    getNameInNamespace in class BaseDirContext
  Returns:
    this context's name in its own namespace; never null
  Throws:
    javax.naming.OperationNotSupportedException - if the naming system does not have the notion of a full name
    javax.naming.NamingException - if a naming exception is encountered

### getAttributes

    public javax.naming.directory.Attributes getAttributes(java.lang.String name,
                                                           java.lang.String[] attrIds)
                                                    throws javax.naming.NamingException

  Retrieves selected attributes associated with a named object. See the class description regarding attribute models, attribute type names, and operational attributes.
  Overrides:
    getAttributes in class BaseDirContext
  Parameters:
    `name` - the name of the object from which to retrieve attributes
    `attrIds` - the identifiers of the attributes to retrieve. null indicates that all attributes should be retrieved; an empty array indicates that none should be retrieved
  Returns:
    the requested attributes; never null
  Throws:
    javax.naming.NamingException - if a naming exception is encountered

### getAttributes

    public javax.naming.directory.Attributes getAttributes(javax.naming.Name name,
                                                           java.lang.String[] attrIds)
                                                    throws javax.naming.NamingException

                          throws javax.naming.NamingException

  Modifies the attributes associated with a named object. The order of the modifications is not specified. Where possible, the modifications are performed atomically.
  Overrides:
    modifyAttributes in class BaseDirContext
  Parameters:
    `name` - the name of the object whose attributes will be updated
    `mod_op` - the modification operation, one of: ADD_ATTRIBUTE, REPLACE_ATTRIBUTE, REMOVE_ATTRIBUTE

                     java.lang.Object obj,
                     javax.naming.directory.Attributes attrs)
              throws javax.naming.NamingException

  Binds a name to an object, along with associated attributes. If attrs is null, the resulting binding will have the attributes associated with obj if obj is a DirContext, and no attributes otherwise. If attrs is non-null, the resulting binding will have attrs as its attributes; any attributes associated with obj are ignored.
  Overrides:
    bind in class BaseDirContext
  Parameters:
    `name` - the name to bind; may not be empty
    `obj` - the object to bind; possibly null
    `attrs` - the attributes to associate with the binding
  Throws:
    javax.naming.NameAlreadyBoundException - if name is already bound
    InvalidAttributesException - if some "mandatory" attributes of the binding are not supplied
    javax.naming.NamingException - if a naming exception is encountered

### rebind

    public void rebind(java.lang.String name,
                       java.lang.Object obj,

                throws javax.naming.NamingException

  Binds a name to an object, along with associated attributes, overwriting any existing binding. If attrs is null and obj is a DirContext, the attributes from obj are used. If attrs is null and obj is not a DirContext, any existing attributes associated with the object already bound in the directory remain unchanged. If attrs is non-null, any existing attributes associated with the object already bound in the directory are removed and attrs is associated with the named object. If obj is a DirContext and attrs is non-null, the attributes of obj are ignored.
  Overrides:
    rebind in class BaseDirContext
  Parameters:
    `name` - the name to bind; may not be empty
    `obj` - the object to bind; possibly null
    `attrs` - the attributes to associate with the binding

    javax.naming.NamingException - if a naming exception is encountered

### createSubcontext

    public javax.naming.directory.DirContext createSubcontext(java.lang.String name,
                                                              javax.naming.directory.Attributes attrs)
                                                       throws javax.naming.NamingException

  Creates and binds a new context, along with associated attributes. This method creates a new subcontext with the given name, binds it in the target context (that named by all but terminal atomic component of the name), and associates the supplied attributes with the newly created object. All intermediate and target contexts must already exist. If attrs is null, this method is equivalent to Context.createSubcontext().
  Overrides:
    createSubcontext in class BaseDirContext
  Parameters:
    `name` - the name of the context to create; may not be empty
    `attrs` - the attributes to associate with the newly created context
  Returns:
    the newly created context
  Throws:
    javax.naming.NameAlreadyBoundException - if the name is already bound
    InvalidAttributesException - if attrs does not contain all the mandatory attributes required for creation
    javax.naming.NamingException - if a naming exception is encountered

### getSchema

    public javax.naming.directory.DirContext getSchema(java.lang.String name)
                                                throws javax.naming.NamingException

  Retrieves the schema associated with the named object. The schema describes rules regarding the structure of the namespace and the attributes stored within it. The schema specifies what types of objects can be added to the directory and where they can be added; what mandatory and optional attributes an object can have. The range of support for schemas is directory-specific.
  Overrides:
    getSchema in class BaseDirContext
  Parameters:
    `name` - the name of the object whose schema is to be retrieved
  Returns:
    the schema associated with the context; never null
  Throws:
    javax.naming.OperationNotSupportedException - if schema not supported
    javax.naming.NamingException - if a naming exception is encountered

### getSchemaClassDefinition

    public javax.naming.directory.DirContext getSchemaClassDefinition(java.lang.String name)
                                                               throws javax.naming.NamingException

  Retrieves a context containing the schema objects of the named object's class definitions.
  Overrides:
    getSchemaClassDefinition in class BaseDirContext
  Parameters:
    `name` - the name of the object whose object class definition is to be retrieved
  Returns:
    the DirContext containing the named object's class definitions; never null
  Throws:
    javax.naming.OperationNotSupportedException - if schema not supported
    javax.naming.NamingException - if a naming exception is encountered

### search

    public javax.naming.NamingEnumeration search(java.lang.String name,
                                                 javax.naming.directory.Attributes matchingAttributes,
                                                 java.lang.String[] attributesToReturn)
                                          throws javax.naming.NamingException

  Searches in a single context for objects that contain a specified set of attributes, and retrieves selected attributes. The search is performed using the default SearchControls settings.
  Overrides:
    search in class BaseDirContext
  Parameters:
    `name` - the name of the context to search
    `matchingAttributes` - the attributes to search for. If empty or null, all objects in the target context are returned.
    `attributesToReturn` - the attributes to return. null indicates that all attributes are to be returned; an empty array indicates that none are to be returned.
  Returns:
    a non-null enumeration of SearchResult objects. Each SearchResult contains the attributes identified by attributesToReturn and the name of the corresponding object, named relative to the context named by name.
  Throws:
    javax.naming.NamingException - if a naming exception is encountered

### search

    public javax.naming.NamingEnumeration search(java.lang.String name,

  Searches in a single context for objects that contain a specified set of attributes. This method returns all the attributes of such objects. It is equivalent to supplying null as the atributesToReturn parameter to the method search(Name, Attributes, String[]).
  Overrides:
    search in class BaseDirContext
  Parameters:
    `name` - the name of the context to search
    `matchingAttributes` - the attributes to search for. If empty or null, all objects in the target context are returned.
  Returns:

  Searches in the named context or object for entries that satisfy the given search filter. Performs the search as specified by the search controls.
  Overrides:
    search in class BaseDirContext
  Parameters:
    `name` - the name of the context or object to search
    `filter` - the filter expression to use for the search; may not be null
    `cons` - the search controls that control the search. If null, the default search controls are used (equivalent to (new SearchControls())).
  Returns:
    an enumeration of SearchResults of the objects that satisfy the filter; never null
  Throws:
    InvalidSearchFilterException - if the search filter specified is not supported or understood by the underlying directory
    InvalidSearchControlsException - if the search controls contain invalid settings
    javax.naming.NamingException - if a naming exception is encountered

                                          throws javax.naming.NamingException

  Searches in the named context or object for entries that satisfy the given search filter. Performs the search as specified by the search controls.
  Overrides:
    search in class BaseDirContext
  Parameters:
    `name` - the name of the context or object to search
    `filterExpr` - the filter expression to use for the search. The expression may contain variables of the form "{i}" where i is a nonnegative integer. May not be null.
    `filterArgs` - the array of arguments to substitute for the variables in filterExpr. The value of filterArgs[i] will replace each occurrence of "{i}". If null, equivalent to an empty array.
    `cons` - the search controls that control the search. If null, the default search controls are used (equivalent to (new SearchControls())).
  Returns:
    an enumeration of SearchResults of the objects that satisy the filter; never null
  Throws:
    ArrayIndexOutOfBoundsException - if filterExpr contains {i} expressions where i is outside the bounds of the array filterArgs
    InvalidSearchControlsException - if cons contains invalid settings
    InvalidSearchFilterException - if filterExpr with filterArgs represents an invalid search filter
    javax.naming.NamingException - if a naming exception is encountered
