Methods Summary |
---|
public java.lang.Object | addToEnvironment(java.lang.String propName, java.lang.Object propVal)Adds a new environment property to the environment of this context. If
the property already exists, its value is overwritten.
return env.put(propName, propVal);
|
protected void | bind(javax.naming.Name name, java.lang.Object obj, boolean rebind)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.
checkWritable();

NamingEntry.CONTEXT);
} else if (toBind instanceof LinkRef) {

NamingEntry.LINK_REF);
} else if (toBind instanceof Reference) {

NamingEntry.ENTRY);
}
bindings.put(name.get(0), entry);
}
}
|
public void | bind(javax.naming.Name name, java.lang.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.
bind(name, obj, false);
|
public void | bind(java.lang.String name, java.lang.Object obj)Binds a name to an object.
bind(new CompositeName(name), obj);
|
protected void | checkWritable()Throws a naming exception is Context is not writable.
if (!isWritable())
throw new NamingException(sm.getString("namingContext.readOnly"));
|
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.
env.clear();
|
public javax.naming.Name | composeName(javax.naming.Name name, javax.naming.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.
prefix = (Name) prefix.clone();
return prefix.addAll(name);
|
public java.lang.String | composeName(java.lang.String name, java.lang.String prefix)Composes the name of this context with a name relative to this context.
return prefix + "/" + name;
|
public javax.naming.Context | createSubcontext(javax.naming.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.
checkWritable();
Context newContext = new NamingContext(env, this.name);
bind(name, newContext);
return newContext;
|
public javax.naming.Context | createSubcontext(java.lang.String name)Creates and binds a new context.
return createSubcontext(new CompositeName(name));
|
public void | destroySubcontext(javax.naming.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.
checkWritable();
while ((!name.isEmpty()) && (name.get(0).length() == 0))
name = name.getSuffix(1);
if (name.isEmpty())
throw new NamingException
(sm.getString("namingContext.invalidName"));
NamingEntry entry = (NamingEntry) bindings.get(name.get(0));
if (entry == null) {
throw new NameNotFoundException
(sm.getString("namingContext.nameNotBound", name.get(0)));
}
if (name.size() > 1) {
if (entry.type == NamingEntry.CONTEXT) {
((Context) entry.value).unbind(name.getSuffix(1));
} else {
throw new NamingException
(sm.getString("namingContext.contextExpected"));
}
} else {
if (entry.type == NamingEntry.CONTEXT) {
((Context) entry.value).close();
bindings.remove(name.get(0));
} else {
throw new NotContextException
(sm.getString("namingContext.contextExpected"));
}
}
|
public void | destroySubcontext(java.lang.String name)Destroys the named context and removes it from the namespace.
destroySubcontext(new CompositeName(name));
|
public java.util.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().
return env;
|
public java.lang.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.
throw new OperationNotSupportedException
(sm.getString("namingContext.noAbsoluteName"));
//FIXME ?
|
public javax.naming.NameParser | getNameParser(javax.naming.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).
while ((!name.isEmpty()) && (name.get(0).length() == 0))
name = name.getSuffix(1);
if (name.isEmpty())
return nameParser;
if (name.size() > 1) {
Object obj = bindings.get(name.get(0));
if (obj instanceof Context) {
return ((Context) obj).getNameParser(name.getSuffix(1));
} else {
throw new NotContextException
(sm.getString("namingContext.contextExpected"));
}
}
return nameParser;
|
public javax.naming.NameParser | getNameParser(java.lang.String name)Retrieves the parser associated with the named context.
return getNameParser(new CompositeName(name));
|
protected boolean | isWritable()Returns true if writing is allowed on this context.
return ContextAccessController.isWritable(name);
|
public javax.naming.NamingEnumeration | list(javax.naming.Name name)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.
// Removing empty parts
while ((!name.isEmpty()) && (name.get(0).length() == 0))
name = name.getSuffix(1);
if (name.isEmpty()) {
return new NamingContextEnumeration(bindings.elements());
}
NamingEntry entry = (NamingEntry) bindings.get(name.get(0));
if (entry == null) {
throw new NameNotFoundException
(sm.getString("namingContext.nameNotBound", name.get(0)));
}
if (entry.type != NamingEntry.CONTEXT) {
throw new NamingException
(sm.getString("namingContext.contextExpected"));
}
return ((Context) entry.value).list(name.getSuffix(1));
|
public javax.naming.NamingEnumeration | list(java.lang.String name)Enumerates the names bound in the named context, along with the class
names of objects bound to them.
return list(new CompositeName(name));
|
public javax.naming.NamingEnumeration | listBindings(javax.naming.Name name)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.
// Removing empty parts
while ((!name.isEmpty()) && (name.get(0).length() == 0))
name = name.getSuffix(1);
if (name.isEmpty()) {
return new NamingContextBindingsEnumeration(bindings.elements());
}
NamingEntry entry = (NamingEntry) bindings.get(name.get(0));
if (entry == null) {
throw new NameNotFoundException
(sm.getString("namingContext.nameNotBound", name.get(0)));
}
if (entry.type != NamingEntry.CONTEXT) {
throw new NamingException
(sm.getString("namingContext.contextExpected"));
}
return ((Context) entry.value).listBindings(name.getSuffix(1));
|
public javax.naming.NamingEnumeration | listBindings(java.lang.String name)Enumerates the names bound in the named context, along with the
objects bound to them.
return listBindings(new CompositeName(name));
|
public java.lang.Object | lookup(javax.naming.Name name)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).
// --------------------------------------------------------- Public Methods
// -------------------------------------------------------- Context Methods
return lookup(name, true);
|
protected java.lang.Object | lookup(javax.naming.Name name, boolean resolveLinks)Retrieves the named object.
// Removing empty parts
while ((!name.isEmpty()) && (name.get(0).length() == 0))
name = name.getSuffix(1);
if (name.isEmpty()) {
// If name is empty, a newly allocated naming context is returned
return new NamingContext(env, this.name, bindings);
}
NamingEntry entry = (NamingEntry) bindings.get(name.get(0));
if (entry == null) {
throw new NameNotFoundException
(sm.getString("namingContext.nameNotBound", name.get(0)));
}
if (name.size() > 1) {
// If the size of the name is greater that 1, then we go through a
// number of subcontexts.
if (entry.type != NamingEntry.CONTEXT) {
throw new NamingException
(sm.getString("namingContext.contextExpected"));
}
return ((Context) entry.value).lookup(name.getSuffix(1));
} else {
if ((resolveLinks) && (entry.type == NamingEntry.LINK_REF)) {
String link = ((LinkRef) entry.value).getLinkName();
if (link.startsWith(".")) {
// Link relative to this context
return lookup(link.substring(1));
} else {
return (new InitialContext(env)).lookup(link);
}
} else if (entry.type == NamingEntry.REFERENCE) {
try {
Object obj = NamingManager.getObjectInstance
(entry.value, name, this, env);

throw new NamingException(e.getMessage());
}
} else {
return entry.value;
}
}
|
public java.lang.Object | lookup(java.lang.String name)Retrieves the named object.
return lookup(new CompositeName(name), true);
|
public java.lang.Object | lookupLink(javax.naming.Name name)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.
return lookup(name, false);
|
public java.lang.Object | lookupLink(java.lang.String name)Retrieves the named object, following links except for the terminal
atomic component of the name.
return lookup(new CompositeName(name), false);
|
public void | rebind(javax.naming.Name name, java.lang.Object obj)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.
bind(name, obj, true);
|
public void | rebind(java.lang.String name, java.lang.Object obj)Binds a name to an object, overwriting any existing binding.
rebind(new CompositeName(name), obj);
|
public java.lang.Object | removeFromEnvironment(java.lang.String propName)Removes an environment property from the environment of this context.
return env.remove(propName);
|
public void | rename(javax.naming.Name oldName, javax.naming.Name newName)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.
Object value = lookup(oldName);
bind(newName, value);
unbind(oldName);
|
public void | rename(java.lang.String oldName, java.lang.String newName)Binds a new name to the object bound to an old name, and unbinds the
old name.
rename(new CompositeName(oldName), new CompositeName(newName));
|
public void | unbind(java.lang.String name)Unbinds the named object.
unbind(new CompositeName(name));
|
public void | unbind(javax.naming.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.
