Class PrePostProcessingCommandInterceptor

java.lang.Object

org.infinispan.commands.AbstractVisitor

org.infinispan.interceptors.base.CommandInterceptor

org.infinispan.interceptors.base.PrePostProcessingCommandInterceptor

public abstract class PrePostProcessingCommandInterceptor
extends CommandInterceptor

This interceptor adds pre and post processing to each visitXXX() method.

For each visitXXX() method invoked, it will first call PrePostProcessingCommandInterceptor.doBeforeCall(InvocationContext, VisitableCommand) and if this method returns true, it will proceed to invoking a handleXXX() method and lastly, PrePostProcessingCommandInterceptor.doAfterCall(InvocationContext, VisitableCommand) in a finally block. Note that the doAfterCall() method is still invoked even if doBeforeCall() returns false.

Instead of overriding visitXXX() methods, implementations should override their handleXXX() counterparts defined in this class instead, as well as the PrePostProcessingCommandInterceptor.doAfterCall(InvocationContext ,VisitableCommand) method and optionally PrePostProcessingCommandInterceptor.doBeforeCall(InvocationContext, VisitableCommand).
