Class InvocationStage

java.lang.Object

org.infinispan.interceptors.InvocationStage

Direct Known Subclasses:

SimpleAsyncInvocationStage, SyncInvocationStage

public abstract class InvocationStage
extends Object

A partial command invocation, either completed or in progress. It is similar to a CompletionStage, but it allows more callback functions to be stateless by passing the context and the invoked command as parameters. Unlike CompletionStage, adding a callback can delay the completion of the initial stage and change its result.

                         VisitableCommand command,
                         InvocationSuccessAction function)

andExceptionally

public Object andExceptionally(InvocationContext ctx,
                               VisitableCommand command,
                               InvocationExceptionFunction function)

andFinally

public Object andFinally(InvocationContext ctx,
                         VisitableCommand command,
                         InvocationFinallyAction action)

andHandle

public Object andHandle(InvocationContext ctx,
                        VisitableCommand command,
