Builds a proxy directory context using the given environment.

Method Detail

addToEnvironment

public Object addToEnvironment(String propName, Object propVal)
Adds a new environment property to the environment of this context. If the property already exists, its value is overwritten.

Parameters: propName the name of the environment property to add; may not be null propVal the value of the property to add; may not be null

Throws: NamingException if a naming exception is encountered

bind

public void bind(Name name, Object obj)
Binds a name to an object. All intermediate contexts and the target context (that named by all but terminal atomic component of the name) must already exist.

Parameters: name the name to bind; may not be empty obj the object to bind; possibly null

Throws: NameAlreadyBoundException if name is already bound InvalidAttributesException if object did not supply all mandatory attributes NamingException if a naming exception is encountered

bind

public void bind(String name, Object obj)
Binds a name to an object.

Parameters: name the name to bind; may not be empty obj the object to bind; possibly null

Throws: NameAlreadyBoundException if name is already bound InvalidAttributesException if object did not supply all mandatory attributes NamingException if a naming exception is encountered

bind

public void bind(Name name, Object obj, Attributes attrs)
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.

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: NameAlreadyBoundException if name is already bound InvalidAttributesException if some "mandatory" attributes of the binding are not supplied NamingException if a naming exception is encountered

cacheLoad

protected void cacheLoad(CacheEntry entry)
Load entry into cache.

cacheLookup

protected CacheEntry cacheLookup(String name)
Lookup in cache.

cacheUnload

protected boolean cacheUnload(String name)
Remove entry from cache.

close

public void close()
Closes this context. This method releases this context's resources immediately, instead of waiting for them to be released automatically by the garbage collector. This method is idempotent: invoking it on a context that has already been closed has no effect. Invoking any other method on a closed context is not allowed, and results in undefined behaviour.

Throws: NamingException if a naming exception is encountered

composeName

public Name composeName(Name name, Name prefix)
Composes the name of this context with a name relative to this context.

Given a name (name) relative to this context, and the name (prefix) of this context relative to one of its ancestors, this method returns the composition of the two names using the syntax appropriate for the naming system(s) involved. That is, if name names an object relative to this context, the result is the name of the same object, but relative to the ancestor context. None of the names may be null.

Parameters: name a name relative to this context prefix the name of this context relative to one of its ancestors

Returns: the composition of prefix and name

Throws: NamingException if a naming exception is encountered

composeName

public String composeName(String name, String prefix)
Composes the name of this context with a name relative to this context.

Parameters: name a name relative to this context prefix the name of this context relative to one of its ancestors

Returns: the composition of prefix and name

Throws: NamingException if a naming exception is encountered

createSubcontext

public Context createSubcontext(Name name)
Creates and binds a new context. Creates a new context with the given name and binds it in the target context (that named by all but terminal atomic component of the name). All intermediate contexts and the target context must already exist.

Parameters: name the name of the context to create; may not be empty

Returns: the newly created context

Throws: NameAlreadyBoundException if name is already bound InvalidAttributesException if creation of the subcontext requires specification of mandatory attributes NamingException if a naming exception is encountered

createSubcontext

public Context createSubcontext(String name)
Creates and binds a new context.

Parameters: name the name of the context to create; may not be empty

Returns: the newly created context

Throws: NameAlreadyBoundException if name is already bound InvalidAttributesException if creation of the subcontext requires specification of mandatory attributes NamingException if a naming exception is encountered

createSubcontext

public DirContext createSubcontext(Name name, Attributes attrs)
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().

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: NameAlreadyBoundException if the name is already bound InvalidAttributesException if attrs does not contain all the mandatory attributes required for creation NamingException if a naming exception is encountered

createSubcontext

public DirContext createSubcontext(String name, Attributes attrs)
Creates and binds a new context, along with associated attributes.

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: NameAlreadyBoundException if the name is already bound InvalidAttributesException if attrs does not contain all the mandatory attributes required for creation NamingException if a naming exception is encountered

destroySubcontext

public void destroySubcontext(Name name)
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.

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

destroySubcontext

public void destroySubcontext(String name)
Destroys the named context and removes it from the namespace.

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

getAttributes

public Attributes getAttributes(Name name)
Retrieves all of the attributes associated with a named object.

Parameters: name the name of the object from which to retrieve attributes

Returns: the set of attributes associated with name. Returns an empty attribute set if name has no attributes; never null.

Returns: the set of attributes associated with name

Throws: NamingException if a naming exception is encountered

getAttributes

public Attributes getAttributes(Name name, String[] attrIds)
Retrieves selected attributes associated with a named object. See the class description regarding attribute models, attribute type names, and operational attributes.

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: NamingException if a naming exception is encountered

getAttributes

public Attributes getAttributes(String name, String[] attrIds)
Retrieves selected attributes associated with a named object.

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

getCache

public ResourceCache getCache()
Get the cache used for this context.

getContextName

public String getContextName()
Return the context name.

getDirContext

public DirContext getDirContext()
Return the actual directory context we are wrapping.

getDocBase

public String getDocBase()
Return the document root for this component.

getEnvironment

public Hashtable getEnvironment()
Retrieves the environment in effect for this context. See class description for more details on environment properties. The caller should not make any changes to the object returned: their effect on the context is undefined. The environment of this context may be changed using addToEnvironment() and removeFromEnvironment().

Returns: the environment of this context; never null

Throws: NamingException if a naming exception is encountered

getHostName

public String getHostName()
Return the host name.

getNameInNamespace

public String getNameInNamespace()
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.

Returns: this context's name in its own namespace; never null

Throws: OperationNotSupportedException if the naming system does not have the notion of a full name NamingException if a naming exception is encountered

getNameParser

public NameParser getNameParser(Name name)
Retrieves the parser associated with the named context. In a federation of namespaces, different naming systems will parse names differently. This method allows an application to get a parser for parsing names into their atomic components using the naming convention of a particular naming system. Within any single naming system, NameParser objects returned by this method must be equal (using the equals() test).

Parameters: name the name of the context from which to get the parser

Returns: a name parser that can parse compound names into their atomic components

Throws: NamingException if a naming exception is encountered

getNameParser

public NameParser getNameParser(String name)

Returns: a name parser that can parse compound names into their atomic components

Throws: NamingException if a naming exception is encountered

getSchema

public DirContext getSchema(Name name)
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.

Parameters: name the name of the object whose schema is to be retrieved

Returns: the schema associated with the context; never null

Throws: OperationNotSupportedException if schema not supported NamingException if a naming exception is encountered

public DirContext getSchemaClassDefinition(Name name)
Retrieves a context containing the schema objects of the named object's class definitions.

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

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 NamingException if a naming exception is encountered

search

public NamingEnumeration search(String name, String filter, SearchControls cons)
Searches in the named context or object for entries that satisfy the given search filter. Performs the search as specified by the search controls.

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 NamingException if a naming exception is encountered

search

public NamingEnumeration search(Name name, String filterExpr, Object[] filterArgs, SearchControls cons)
Searches in the named context or object for entries that satisfy the given search filter. Performs the search as specified by the search controls.

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 NamingException if a naming exception is encountered

search

public NamingEnumeration search(String name, String filterExpr, Object[] filterArgs, SearchControls cons)
Searches in the named context or object for entries that satisfy the given search filter. Performs the search as specified by the search controls.

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 NamingException if a naming exception is encountered

unbind

public void unbind(Name name)
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.

Parameters: name the name to bind; may not be empty

Throws: NameNotFoundException if an intermediate context does not exist NamingException if a naming exception is encountered

unbind

public void unbind(String name)
Unbinds the named object.

Parameters: name the name to bind; may not be empty

Throws: NameNotFoundException if an intermediate context does not exist NamingException if a naming exception is encountered

validate

protected boolean validate(CacheEntry entry)
Validate entry.
