Class InfinispanSource

java.lang.Object
  org.jboss.dna.connector.infinispan.InfinispanSource

All Implemented Interfaces:

Serializable, Referenceable, ObjectFactory, MapRepositorySource, RepositorySource

@ThreadSafe
public class InfinispanSource
extends Object
implements MapRepositorySource, ObjectFactory

A repository source that uses an Infinispan instance to manage the content. This source is capable of using an existing CacheManager or creating a new cache manager. This process is controlled entirely by the JavaBean properties of the InfinispanSource instance.

This source first attempts to find an existing cache manager found in JNDI (or the DefaultCacheManager if no such manager is available) and the cache configuration name if supplied or the default configuration if not set.

Like other RepositorySource classes, instances of JBossCacheSource can be placed into JNDI and do support the creation of JNDI referenceable objects and resolution of references into JBossCacheSource.

close

public void close()

Signal this source that it is no longer needed and should begin the process of reclaiming or closing all resources that it has acquired. Because connections may still be in use, this method may not necessarily close all resources immediately.

This is a required method, and must be called when this source is no longer needed if one or more connections have been obtained since the previous call to this method.

Note that calling this method also does not preclude obtaining more connections after this method is called. If that happens, this source should simply reacquire any resources necessary to provide additional connections, and this method needs to be called once again.

close in interface RepositorySource

Description copied from interface: MapRepositorySource

Returns the repository context for the repository source

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

getReference

public Reference getReference()
