This gives rise to the possibility of a cycle of links whose 0N/A * resolution could not terminate normally. As a simple means to avoid such 0N/A * non-terminating resolutions, service providers may define limits on the 0N/A * number of links that may be involved in any single operation invoked 0N/A * A LinkRef contains a single StringRefAddr, whose type is "LinkAddress", 0N/A * and whose contents is the link name. The class name field of the 0N/A * Reference is that of this (LinkRef) class. 0N/A * LinkRef is bound to a name using the normal Context.bind()/rebind(), and 0N/A * DirContext.bind()/rebind(). Context.lookupLink() is used to retrieve the link 0N/A * itself if the terminal atomic name is bound to a link. 0N/A * Many naming systems support a native notion of link that may be used 0N/A * within the naming system itself. JNDI does not specify whether 0N/A * there is any relationship between such native links and JNDI links. 0N/A * A LinkRef instance is not synchronized against concurrent access by multiple 0N/A * threads. Threads that need to access a LinkRef instance concurrently should 0N/A * synchronize amongst themselves and provide the necessary locking. 0N/A * @author Rosanna Lee 0N/A * @author Scott Seligman 0N/A * @see LinkException 0N/A * @see LinkLoopException 0N/A * @see MalformedLinkException 0N/A * @see Context#lookupLink 0N/A * The serialized form of a LinkRef object consists of the serialized 0N/A * fields of its Reference superclass. 0N/A /* code for link handling */ 0N/A * Constructs a LinkRef for a name. 0N/A * @param linkName The non-null name for which to create this link. 0N/A * Constructs a LinkRef for a string name. 0N/A * @param linkName The non-null name for which to create this link. 0N/A * Retrieves the name of this link. 0N/A * @return The non-null name of this link. 0N/A * @exception MalformedLinkException If a link name could not be extracted 0N/A * @exception NamingException If a naming exception was encountered. 0N/A * Use serialVersionUID from JNDI 1.1.1 for interoperability
