Package ch.rswk.meta.engine

Class ActionService

java.lang.Object

com.google.common.util.concurrent.AbstractIdleService

ch.rswk.meta.engine.AbstractEngineIdleService<ActionService.ActionServiceConfig>

ch.rswk.meta.engine.ActionService

All Implemented Interfaces:

EngineServices.ConfigurableService<ActionService.ActionServiceConfig>, EngineServices.InfoProvidingService, com.google.common.util.concurrent.Service

@Singleton
public class ActionService
extends AbstractEngineIdleService<ActionService.ActionServiceConfig>

ActionService receives and dispatches MetaAction to services that are registered to handle them. Does validation of parameter and result schemas, in case schemas are defined.
