Java Source Code / Java Documentation » Search Engine » apache solr 1.2.0 » org.apache.solr.util   Source Cross Reference   Class Diagram   Java Document (Java Doc)   java.lang.Object    org.apache.solr.util.RefCounted RefCounted abstract public class RefCounted (Code) Keep track of a reference count on a resource and close it when the count hits zero. By itself, this class could have some race conditions since there is no synchronization between the refcount check and the close. Solr's use in reference counting searchers is safe since the count can only hit zero if it's unregistered (and hence incref() will not be called again on it). author:    yonik version:    $Id: RefCounted.java 542583 2007-05-29 16:33:23Z yonik $ Field Summary final protected  AtomicInteger refcount      final protected  Type resource      Constructor Summary public   RefCounted(Type resource)      Method Summary abstract protected  void close()      public  void decref()      final public  Type get()      final public  RefCounted<Type> incref()      Field Detail refcount final protected AtomicInteger refcount(Code) resource final protected Type resource(Code) Constructor Detail RefCounted public RefCounted(Type resource)(Code) Method Detail close abstract protected void close()(Code) decref public void decref()(Code) get final public Type get()(Code) incref final public RefCounted<Type> incref()(Code) Methods inherited from java.lang.Object native protected Object clone() throws CloneNotSupportedException(Code)(Java Doc) public boolean equals(Object obj)(Code)(Java Doc) protected void finalize() throws Throwable(Code)(Java Doc) final native public Class getClass()(Code)(Java Doc) native public int hashCode()(Code)(Java Doc) final native public void notify()(Code)(Java Doc) final native public void notifyAll()(Code)(Java Doc) public String toString()(Code)(Java Doc) final native public void wait(long timeout) throws InterruptedException(Code)(Java Doc) final public void wait(long timeout, int nanos) throws InterruptedException(Code)(Java Doc) final public void wait() throws InterruptedException(Code)(Java Doc)
