LinkRef

Class Overview

This class represents a Reference whose contents is a name, called the link name, that is bound to an atomic name in a context.

The name is a URL, or a name to be resolved relative to the initial context, or if the first character of the name is ".", the name is relative to the context in which the link is bound.

Normal resolution of names in context operations always follow links. Resolution of the link name itself may cause resolution to pass through other links. This gives rise to the possibility of a cycle of links whose resolution could not terminate normally. As a simple means to avoid such non-terminating resolutions, service providers may define limits on the number of links that may be involved in any single operation invoked by the caller.

A LinkRef contains a single StringRefAddr, whose type is "LinkAddress", and whose contents is the link name. The class name field of the Reference is that of this (LinkRef) class.

LinkRef is bound to a name using the normal Context.bind()/rebind(), and DirContext.bind()/rebind(). Context.lookupLink() is used to retrieve the link itself if the terminal atomic name is bound to a link.

Many naming systems support a native notion of link that may be used within the naming system itself. JNDI does not specify whether there is any relationship between such native links and JNDI links.

A LinkRef instance is not synchronized against concurrent access by multiple threads. Threads that need to access a LinkRef instance concurrently should synchronize amongst themselves and provide the necessary locking.

From class javax.naming.Reference void add(int posn, RefAddr addr) Adds an address to the list of addresses at index posn. void add(RefAddr addr) Adds an address to the end of the list of addresses. void clear() Deletes all addresses from this reference. Object clone() Makes a copy of this reference using its class name list of addresses, class factory name and class factory location. boolean equals(Object obj) Determines whether obj is a reference with the same addresses (in same order) as this reference. RefAddr get(int posn) Retrieves the address at index posn. RefAddr get(String addrType) Retrieves the first address that has the address type 'addrType'. Enumeration<RefAddr> getAll() Retrieves an enumeration of the addresses in this reference. String getClassName() Retrieves the class name of the object to which this reference refers. String getFactoryClassLocation() Retrieves the location of the factory of the object to which this reference refers. String getFactoryClassName() Retrieves the class name of the factory of the object to which this reference refers. int hashCode() Computes the hash code of this reference. Object remove(int posn) Deletes the address at index posn from the list of addresses. int size() Retrieves the number of addresses in this reference. String toString() Generates the string representation of this reference.
From class java.lang.Object Object clone() Creates and returns a copy of this object. boolean equals(Object obj) Indicates whether some other object is "equal to" this one. void finalize() Called by the garbage collector on an object when garbage collection determines that there are no more references to the object. final Class<?> getClass() Returns the runtime class of this Object. int hashCode() Returns a hash code value for the object. final void notify() Wakes up a single thread that is waiting on this object's monitor. final void notifyAll() Wakes up all threads that are waiting on this object's monitor. String toString() Returns a string representation of the object. final void wait() Causes the current thread to wait until another thread invokes the notify() method or the notifyAll() method for this object. final void wait(long timeout, int nanos) Causes the current thread to wait until another thread invokes the notify() method or the notifyAll() method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed. final void wait(long timeout) Causes the current thread to wait until either another thread invokes the notify() method or the notifyAll() method for this object, or a specified amount of time has elapsed.
