Method Detail

getActivity

PvmActivity getActivity()

returns the current PvmActivity of the execution.

enterActivityInstance

void enterActivityInstance()

invoked to notify the execution that a new activity instance is started

leaveActivityInstance

void leaveActivityInstance()

invoked to notify the execution that an activity instance is ended.

setActivityInstanceId

void setActivityInstanceId(String id)

getActivityInstanceId

String getActivityInstanceId()

return the Id of the activity instance currently executed by this execution

Specified by:

getActivityInstanceId in interface DelegateExecution

getParentActivityInstanceId

String getParentActivityInstanceId()

return the Id of the parent activity instance currently executed by this execution

Specified by:

getParentActivityInstanceId in interface DelegateExecution

take

void take(PvmTransition transition)

leaves the current activity by taking the given transition.

createExecution

ActivityExecution createExecution()

creates a new execution. This execution will be the parent of the newly created execution. properties processDefinition, processInstance and activity will be initialized.

createExecution

ActivityExecution createExecution(boolean initializeExecutionStartContext)

creates a new execution. This execution will be the parent of the newly created execution. properties processDefinition, processInstance and activity will be initialized.

createSubProcessInstance

PvmProcessInstance createSubProcessInstance(PvmProcessDefinition processDefinition)

creates a new sub process instance. The current execution will be the super execution of the created execution.

Parameters:

processDefinition - The PvmProcessDefinition of the subprocess.

createSubProcessInstance

PvmProcessInstance createSubProcessInstance(PvmProcessDefinition processDefinition,
                                            String businessKey)

Parameters:

processDefinition - The PvmProcessDefinition of the subprocess.

businessKey - the business key of the process instance

See Also:

createSubProcessInstance(PvmProcessDefinition)

createSubProcessInstance

PvmProcessInstance createSubProcessInstance(PvmProcessDefinition processDefinition,
                                            String businessKey,
                                            String caseInstanceId)

Parameters:

processDefinition - The PvmProcessDefinition of the subprocess.

businessKey - the business key of the process instance

caseInstanceId - the case instance id of the process instance

See Also:

createSubProcessInstance(PvmProcessDefinition)

getParent

ActivityExecution getParent()

returns the parent of this execution, or null if there no parent.

getExecutions

List<? extends ActivityExecution> getExecutions()

returns the list of execution of which this execution the parent of.

end

void end(boolean isScopeComplete)

ends this execution.

endCompensation

void endCompensation()

Execution finished compensation. Removes this execution and notifies listeners.

returns whether this execution is currently active.

isEnded

boolean isEnded()

returns whether this execution has ended or not.

void setConcurrent(boolean isConcurrent)

changes the concurrent indicator on this execution.

isConcurrent

boolean isConcurrent()

returns whether this execution is concurrent or not.

isProcessInstanceExecution

boolean isProcessInstanceExecution()

returns whether this execution is a process instance or not.

inactivate

void inactivate()
