Class ActivitiStateHandlerRegistry

java.lang.Object

org.camunda.bpm.engine.impl.bpmn.behavior.FlowNodeActivityBehavior

org.camunda.bpm.engine.impl.bpmn.behavior.AbstractBpmnActivityBehavior

org.camunda.bpm.engine.impl.bpmn.behavior.TaskActivityBehavior

org.camunda.bpm.engine.spring.components.registry.ActivitiStateHandlerRegistry

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 org.camunda.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).

Since:

1.0

Method Detail

setProcessEngine

public void setProcessEngine(ProcessEngine processEngine)

execute

public void execute(ActivityExecution execution)
             throws Exception

Description copied from class: FlowNodeActivityBehavior

Default behaviour: just leave the activity with no extra functionality.

Specified by:

execute in interface CoreActivityBehavior<ActivityExecution>

Specified by:

execute in interface ActivityBehavior

Overrides:

execute in class TaskActivityBehavior

Throws:

Exception

signal

public void signal(ActivityExecution execution,
          String signalName,
          Object data)
            throws Exception

Specified by:

signal in interface SignallableActivityBehavior

Overrides:

signal in class ReceiveTaskActivityBehavior

Throws:

Exception

registrationKey

protected String registrationKey(String stateName,
                     String processName)

registerActivitiStateHandler

public void registerActivitiStateHandler(ActivitiStateHandlerRegistration registration)

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

Parameters:

registration - the org.camunda.bpm.engine.test.spring.components.registry.ActivitiStateHandlerRegistration

findRegistrationsForProcessAndState

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

this is responsible for looking up components in the registry and returning the appropriate handler based on specificity of the org.camunda.bpm.engine.test.spring.components.registry.ActivitiStateHandlerRegistration

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 nanme

Parameters:

processName - the name of the process

stateName - the name of the state

Returns:

an unambiguous org.camunda.bpm.engine.test.spring.components.registry.ActivitiStateHandlerRegistry or null
