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.

- Throws:
NamingException
- if a naming exception is encountered
-
listBindings
public NamingEnumeration<Binding> listBindings(Name name) throws 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.

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:
NamingException
- if a naming exception is encountered
-
destroySubcontext
public void destroySubcontext(Name name) throws 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.
- Specified by:
destroySubcontext
in interfaceContext
- Parameters:
name
- the name of the context to be destroyed; may not be empty- Throws:
NameNotFoundException
- if an intermediate context does not existNotContextException

-
destroySubcontext
public void destroySubcontext(String name) throws NamingException
Destroys the named context and removes it from the namespace.- Specified by:
destroySubcontext
in interfaceContext
- Parameters:
name
- the name of the context to be destroyed; may not be empty- Throws:
NameNotFoundException
- if an intermediate context does not existNotContextException
- if the name is bound but does not name a context, or does not name a context of the appropriate typeNamingException
-
createSubcontext
public Context createSubcontext(Name name) throws NamingException
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.- Specified by:
createSubcontext
in interfaceContext
- Parameters:
name
- the name of the context to create; may not be empty- Returns:
- the newly created context

-
getNameParser
public NameParser getNameParser(Name name) throws NamingException
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).- Specified by:
getNameParser
in interfaceContext
- 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) throws NamingException
Retrieves the parser associated with the named context.- Specified by:
getNameParser
in interfaceContext
- 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
-
composeName
public Name composeName(Name name, Name prefix) throws NamingException
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.
- Specified by:
composeName
in interfaceContext
- Parameters:
name
- a name relative to this contextprefix
- 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) throws NamingException
Composes the name of this context with a name relative to this context.- Specified by:
composeName
in interfaceContext
- Parameters:
name
- a name relative to this contextprefix
- 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
-
addToEnvironment
public Object addToEnvironment(String propName, Object propVal) throws NamingException
Adds a new environment property to the environment of this context. If the property already exists, its value is overwritten.- Specified by:
addToEnvironment
in interfaceContext
- Parameters:
propName
- the name of the environment property to add; may not be nullpropVal

NamingException
- if a naming exception is encountered
-
getEnvironment
public Hashtable<?,?> getEnvironment() throws NamingException
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().- Specified by:
getEnvironment
in interfaceContext
- Returns:
- the environment of this context; never null
- Throws:
NamingException
- if a naming exception is encountered
-
close
public void close() throws NamingException
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.- Specified by:
close
in interfaceContext
- Throws:
NamingException
- if a naming exception is encountered
-
getNameInNamespace
public String getNameInNamespace() throws 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.
- Specified by:
getNameInNamespace
in interfaceContext
- 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 nameNamingException
- if a naming exception is encountered
-
