closeback to summary
public void close() throws NamingException

Implements javax.naming.Context.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.

Annotations
@Override

NamingException:

composeNameback to summary
public Name composeName(Name name, Name prefix) throws NamingException

Implements javax.naming.Context.composeName.

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:Name

a name relative to this context

prefix:Name

the name of this context relative to one of its ancestors

Returns:Name

the composition of prefix and name

Annotations
@Override

composeNameback to summary
public String composeName(String name, String prefix)

Implements javax.naming.Context.composeName.

Composes the name of this context with a name relative to this context.

Parameters
name:String

a name relative to this context

prefix:String

the name of this context relative to one of its ancestors

Returns:String

the composition of prefix and name

Annotations
@Override
createSubcontextback to summary
public Context createSubcontext(Name name) throws NamingException

Implements javax.naming.Context.createSubcontext.

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:Name

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

Returns:Context

the newly created context

Annotations

NameAlreadyBoundException:

createSubcontextback to summary
public Context createSubcontext(String name) throws NamingException

Implements javax.naming.Context.createSubcontext.

Creates and binds a new context.

Parameters
name:String

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

Returns:Context

the newly created context

Annotations
@Override
Exceptions
NamingException:
if a naming exception is encountered
NameAlreadyBoundException:
if name is already bound
InvalidAttributesException:
if creation of the sub-context requires specification of mandatory attributes
destroySubcontextback to summary
public void destroySubcontext(Name name) throws NamingException

Implements javax.naming.Context.destroySubcontext.

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:Name

the name of the context to be destroyed; may not be empty

getEnvironmentback to summary
public Hashtable<?, ?> getEnvironment()

Implements javax.naming.Context.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:Hashtable<?, ?>

the environment of this context; never null

public boolean getExceptionOnFailedWrite()
getNameInNamespaceback to summary
public String getNameInNamespace() throws NamingException

Implements javax.naming.Context.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:String

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

Annotations
@Override
Exceptions
NamingException:
if a naming exception is encountered
OperationNotSupportedException:
if the naming system does not have the notion of a full name
getNameParserback to summary
public NameParser getNameParser(Name name) throws NamingException

Implements javax.naming.Context.getNameParser.

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:Name

the name of the context from which to get the parser

Returns:NameParser

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