Class PvmAtomicOperationCreateConcurrentExecution

java.lang.Object

org.camunda.bpm.engine.impl.pvm.runtime.operation.PvmAtomicOperationCreateConcurrentExecution

All Implemented Interfaces:

CoreAtomicOperation<PvmExecutionImpl>, AtomicOperation, PvmAtomicOperation

Direct Known Subclasses:

PvmAtomicOperationActivityStartConcurrent

public abstract class PvmAtomicOperationCreateConcurrentExecution
extends Object
implements PvmAtomicOperation

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.
