Class TaskActivityBehavior

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

All Implemented Interfaces:

CoreActivityBehavior<ActivityExecution>, ActivityBehavior, SignallableActivityBehavior

Direct Known Subclasses:

ManualTaskActivityBehavior, ReceiveTaskActivityBehavior, ScriptTaskActivityBehavior, ServiceTaskDelegateExpressionActivityBehavior, ServiceTaskExpressionActivityBehavior, ServiceTaskJavaDelegateActivityBehavior, UserTaskActivityBehavior

public class TaskActivityBehavior
extends AbstractBpmnActivityBehavior

Parent class for all BPMN 2.0 task types such as ServiceTask, ScriptTask, UserTask, etc. When used on its own, it behaves just as a pass-through activity.
