pentaho.type.action.impl.Target. GenericActionExecution

The GenericActionExecution class is an inner class of Target that assumes that that the execution target is a Target.

It provides a generic implementation of Execution which delegates to the event observers of each of the execution phases, by calling the correspondingly named methods of target: Target#_emitActionPhaseInitEvent, Target#_emitActionPhaseWillEvent Target#_emitActionPhaseDoEvent and Target#_emitActionPhaseFinallyEvent.

 // - Method 1
 event.reject("Cannot do this action now.");

 // - Method 2
 event.reject(new UserError("Cannot do this action now."));
