Class AtomicOperationCreateConcurrentExecution

java.lang.Object
  org.camunda.bpm.engine.impl.pvm.runtime.AtomicOperationCreateConcurrentExecution

All Implemented Interfaces:

AtomicOperation

Direct Known Subclasses:

AtomicOperationActivityStartConcurrent

public abstract class AtomicOperationCreateConcurrentExecution
extends Object
implements AtomicOperation

Base atomic operation used for implementing atomic operations which create a new concurrent execution for executing an activity. This atomic operation makes sure the execution is created under the correct parent.
