All known Subclasses: org.apache.naming.core.BaseDirContext, org.apache.naming.modules.java.SelectorContext,
BaseContext | public class BaseContext extends BaseNaming implements Context(Code) | | Base Context implementation. Use it if the source doesn't support attributes.
Implements all JNDI methods with reasonable defaults or UnsuportedOperation.
IMPORTANT: all contexts should use setters/getters for configuration, instead
of the Hashtable. The default constructor will use introspection to configure
and may provide ( via a hook ? ) JMX management on all contexts.
All methods use Name variant. They should expect an arbitrary implementation, but
it's recommended to check if ServerName is used - and take advantage of the
specific features ( MessageBytes, etc ).

BaseContext | public BaseContext()(Code) | | |
addToEnvironment | public Object addToEnvironment(String propName, Object propVal) throws NamingException(Code) | | 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 notbe null Parameters: propVal - the value of the property to add; may not be null exception: javax.naming.NamingException - if a naming exception is encountered |
bind | public void bind(Name name, Object obj) throws NamingException(Code) | | 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 Parameters: obj - the object to bind; possibly null exception: javax.naming.NameAlreadyBoundException - if name is already bound exception: javax.naming.NamingException - if a naming exception is encountered |
close | public void close() throws NamingException(Code) | | 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.
exception: javax.naming.NamingException - if a naming exception is encountered |
composeName | public Name composeName(Name name, Name prefix) throws NamingException(Code) | | 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 Parameters: prefix - the name of this context relative to one of its ancestors the composition of prefix and name exception: javax.naming.NamingException - if a naming exception is encountered |
composeName | public String composeName(String name, String prefix) throws NamingException(Code) | | Composes the name of this context with a name relative to this context.
Parameters: name - a name relative to this context Parameters: prefix - the name of this context relative to one of its ancestors the composition of prefix and name exception: javax.naming.NamingException - if a naming exception is encountered |
createSubcontext | public Context createSubcontext(Name name) throws NamingException(Code) | | 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 the newly created context exception: javax.naming.NameAlreadyBoundException - if name is already bound exception: javax.naming.NamingException - if a naming exception is encountered |
destroySubcontext | public void destroySubcontext(Name name) throws NamingException(Code) | | 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 exception: javax.naming.NameNotFoundException - if an intermediate context does notexist exception: javax.naming.NotContextException - if the name is bound but does not namea context, or does not name a context of the appropriate type |
getEnvironment | public Hashtable getEnvironment() throws NamingException(Code) | | 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().
the environment of this context; never null exception: javax.naming.NamingException - if a naming exception is encountered |
getNameInNamespace | public String getNameInNamespace() throws NamingException(Code) | | 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.
this context's name in its own namespace; never null exception: javax.naming.OperationNotSupportedException - if the naming system doesnot have the notion of a full name exception: javax.naming.NamingException - if a naming exception is encountered |
getNameParser | public NameParser getNameParser(Name name) throws NamingException(Code) | | 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 a name parser that can parse compound names into their atomiccomponents exception: javax.naming.NamingException - if a naming exception is encountered |
getNameParser | public NameParser getNameParser(String name) throws NamingException(Code) | | Retrieves the parser associated with the named context.
Parameters: name - the name of the context from which to get the parser a name parser that can parse compound names into their atomiccomponents exception: javax.naming.NamingException - if a naming exception is encountered |
list | public NamingEnumeration list(String name) throws NamingException(Code) | | 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.
Parameters: name - the name of the context to list an enumeration of the names and class names of the bindings inthis context. Each element of the enumeration is of type NameClassPair. exception: javax.naming.NamingException - if a naming exception is encountered |
listBindings | public NamingEnumeration listBindings(Name name) throws NamingException(Code) | | Enumerates the names bound in the named context, along with the

an enumeration previously returned is undefined.
Parameters: name - the name of the context to list an enumeration of the bindings in this context.Each element of the enumeration is of type Binding. exception: javax.naming.NamingException - if a naming exception is encountered |
lookup | public Object lookup(Name name) throws NamingException(Code) | | 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).
Parameters: name - the name of the object to look up the object bound to name exception: javax.naming.NamingException - if a naming exception is encountered |
lookupLink | public Object lookupLink(Name name) throws NamingException(Code) | | 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.

lookupLink | public Object lookupLink(String name) throws NamingException(Code) | | Retrieves the named object, following links except for the terminal
atomic component of the name.
Parameters: name - the name of the object to look up the object bound to name, not following the terminal link(if any). exception: javax.naming.NamingException - if a naming exception is encountered |
rebind | public void rebind(Name name, Object obj) throws NamingException(Code) | | 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.
Parameters: name - the name to bind; may not be empty Parameters: obj - the object to bind; possibly null exception: javax.naming.NamingException - if a naming exception is encountered |

Parameters: propName - the name of the environment property to remove;may not be null exception: javax.naming.NamingException - if a naming exception is encountered |
rename | public void rename(String oldName, String newName) throws NamingException(Code) | | 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.
