java.lang.Object	handleDefault(InvocationContext ctx, VisitableCommand command) Deprecated. The default behaviour of the visitXXX methods, which is to ignore the call and pass the call up to the next interceptor in the chain.
java.lang.Object	invoke(InvocationContext ctx) Deprecated. Using this method call for forwarding a call in the chain is not redable and error prone in the case of interceptors extending other interceptors.
java.lang.Object	nextInterceptor(InvocationContext ctx) Deprecated. Forwards the call to the nextInterceptor interceptor in the chain.

invoke

                        throws java.lang.Throwable

Deprecated.

Using this method call for forwarding a call in the chain is not redable and error prone in the case of interceptors extending other interceptors. This metod rather refers to interceptor doing its business operations rather than delegating to the nextInterceptor interceptor in chain. For delegation please use nextInterceptor(org.jboss.cache.InvocationContext)

Throws:

java.lang.Throwable

nextInterceptor

public java.lang.Object nextInterceptor(InvocationContext ctx)
                                 throws java.lang.Throwable

Deprecated.

Forwards the call to the nextInterceptor interceptor in the chain. This is here for backward compatibility.

Throws:

java.lang.Throwable

toString

public java.lang.String toString()

Deprecated.

Overrides:

toString in class java.lang.Object

handleDefault

public java.lang.Object handleDefault(InvocationContext ctx,
                                      VisitableCommand command)
                               throws java.lang.Throwable

Deprecated.
