InitialContext

Field holding the result of calling NamingManager.getInitialContext(). It is set by getDefaultInitCtx() the first time getDefaultInitCtx() is called. Subsequent invocations of getDefaultInitCtx() return the value of defaultInitCtx.

Field indicating whether the initial context has been obtained by calling NamingManager.getInitialContext(). If true, its result is in defaultInitCtx.

The environment associated with this InitialContext. It is initialized to null and is updated by the constructor that accepts an environment or by the init() method.

Constructs an initial context. No environment properties are supplied. Equivalent to new InitialContext(null).

Constructs an initial context using the supplied environment. Environment properties are discussed in the class description.

This constructor will not modify environment or save a reference to it, but may save a clone.

Constructs an initial context with the option of not initializing it. This may be used by a constructor in a subclass when the value of the environment parameter is not yet known at the time the InitialContext constructor is called. The subclass's constructor will call this constructor, compute the value of the environment, and then call init() before returning.

Adds a new environment property to the environment of this context. If the property already exists, its value is overwritten. See class description for more details on environment properties.

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.

Binds a name to an object. See bind(Name, Object) for details.

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.

Composes the name of this context with a name relative to this context. Since an initial context may never be named relative to any context other than itself, the value of the prefix parameter must be an empty name ("").

Composes the name of this context with a name relative to this context. Since an initial context may never be named relative to any context other than itself, the value of the prefix parameter must be an empty 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.

Creates and binds a new context. See createSubcontext(Name) for details.

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.

Destroys the named context and removes it from the namespace. See destroySubcontext(Name) for details.

A static method to retrieve the named object. This is a shortcut method equivalent to invoking:

InitialContext ic = new InitialContext(); Object obj = ic.lookup();

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).

A static method to retrieve the named object. See doLookup(Name) for details.

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().

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.

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).

Retrieves the parser associated with the named context. See getNameParser(Name) for details.

Enumerates the names bound in the named context, along with the class names of objects bound to them. See list(Name) for details.

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.

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.

Enumerates the names bound in the named context, along with the objects bound to them. See listBindings(Name) for details.

Retrieves the named object. See lookup(Name) for details.

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).

Retrieves the named object, following links except for the terminal atomic component of the name. See lookupLink(Name) for details.

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.

Binds a name to an object, overwriting any existing binding. See rebind(Name, Object) for details.

Binds a name to an object, overwriting any existing binding. All intermediate contexts and the target context (that named by all but terminal atomic component of the name) must already exist.

If the object is a DirContext, any existing attributes associated with the name are replaced with those of the object. Otherwise, any existing attributes associated with the name remain unchanged.

Removes an environment property from the environment of this context. See class description for more details on environment properties.

Binds a new name to the object bound to an old name, and unbinds the old name. See rename(Name, Name) for details.

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.

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.

Any attributes associated with the name are removed. Intermediate contexts are not changed.

Unbinds the named object. See unbind(Name) for details.

Retrieves the initial context by calling NamingManager.getInitialContext() and cache it in defaultInitCtx. Set gotDefault so that we know we've tried this before.

Retrieves a context for resolving the string name name. If name name is a URL string, then attempt to find a URL context for it. If none is found, or if name is not a URL string, then return getDefaultInitCtx().

See getURLOrDefaultInitCtx(Name) for description of how a subclass should use this method.

Retrieves a context for resolving name. If the first component of name name is a URL string, then attempt to find a URL context for it. If none is found, or if the first component of name is not a URL string, then return getDefaultInitCtx().

When creating a subclass of InitialContext, use this method as follows. Define a new method that uses this method to get an initial context of the desired subclass.

 protected XXXContext getURLOrDefaultInitXXXCtx(Name name)
 throws NamingException {
  Context answer = getURLOrDefaultInitCtx(name);
  if (!(answer instanceof XXXContext)) {
    if (answer == null) {
      throw new NoInitialContextException();
    } else {
      throw new NotContextException("Not an XXXContext");
    }
  }
  return (XXXContext)answer;
 }
 

 public Object XXXMethod1(Name name, ...) {
  throws NamingException {
    return getURLOrDefaultInitXXXCtx(name).XXXMethod1(name, ...);
 }
 

Initializes the initial context using the supplied environment. Environment properties are discussed in the class description.

This method will modify environment and save a reference to it. The caller may no longer modify it.
