All Implemented Interfaces:

CoreActivityBehavior<ActivityExecution>, ActivityBehavior, SignallableActivityBehavior, org.springframework.beans.factory.Aware, org.springframework.beans.factory.BeanFactoryAware, org.springframework.beans.factory.BeanNameAware, org.springframework.beans.factory.InitializingBean

public class ActivitiStateHandlerRegistry
extends ReceiveTaskActivityBehavior
implements org.springframework.beans.factory.BeanFactoryAware, org.springframework.beans.factory.BeanNameAware, ActivityBehavior, org.springframework.beans.factory.InitializingBean

this class records and manages all known

invalid reference

org.operaton.bpm.engine.annotations.State

- responding beans in the JVM. It should have metadata on all methods, and what those methods expect from a given invocation (ie: which process, which process variables).

registerActivitiStateHandler

public void registerActivitiStateHandler(ActivitiStateHandlerRegistration registration)

used at runtime to register state handlers as they are registered with the spring context

Parameters:

registration - the ActivitiStateHandlerRegistration

findRegistrationsForProcessAndState

public Collection<ActivitiStateHandlerRegistration> findRegistrationsForProcessAndState(String processName,
 String stateName)

Parameters:

processName - the process name to look for (optional)

stateName - the state name to look for (not optional)

Returns:

all matching options

findRegistrationForProcessAndState

public ActivitiStateHandlerRegistration findRegistrationForProcessAndState(String processName,
 String stateName)

this scours the registry looking for candidate registrations that match a given process name and/ or state name

Parameters:

processName - the name of the process

stateName - the name of the state

Returns:

an unambiguous ActivitiStateHandlerRegistry or null
