Class SkipCheckChainedInterceptor

java.lang.Object
  org.jboss.cache.commands.AbstractVisitor
      org.jboss.cache.interceptors.base.CommandInterceptor
          org.jboss.cache.interceptors.base.SkipCheckChainedInterceptor

All Implemented Interfaces:

Visitor

Direct Known Subclasses:

CacheStoreInterceptor

public abstract class SkipCheckChainedInterceptor
extends CommandInterceptor

This interceptor will call skipInterception(org.jboss.cache.InvocationContext ,org.jboss.cache.commands.VisitableCommand) before invoking each visit method (and the handleDefault(org.jboss.cache.InvocationContext , org.jboss.cache.commands.VisitableCommand) method). If skipInterception(org.jboss.cache.InvocationContext ,org.jboss.cache.commands.VisitableCommand) returns false, the invocation will be skipped and passed up the interceptor chain instead.

Instead of overriding visitXXX() methods, implementations should override their handleXXX() counterparts defined in this class instead, as well as the skipInterception(org.jboss.cache.InvocationContext ,org.jboss.cache.commands.VisitableCommand) method. Also, instead of overriding handleDefault(org.jboss.cache.InvocationContext , org.jboss.cache.commands.VisitableCommand), implementors should override handleAll(org.jboss.cache.InvocationContext , org.jboss.cache.commands.VisitableCommand).
