Method Detail

exit

void exit(ProcessInstanceUUID processInstanceUUID)
          throws InstanceNotFoundException

Exit the given instance.

Parameters:

processInstanceUUID - the Id of the instance to exit.

Throws:

InstanceNotFoundException - thrown if the given instance to exit is not found.

resume

void resume(ProcessInstanceUUID processInstanceUUID)
            throws InstanceNotFoundException

Resume a previously suspend instance of a process.

Parameters:

processInstanceUUID - the process instance UUID that identify the instance to resume.

Throws:

InstanceNotFoundException - thrown if the given instance to resume is not found.

suspend

void suspend(ProcessInstanceUUID processInstanceUUID)
             throws InstanceNotFoundException

Suspend the given instance of a process.

Parameters:

processInstanceUUID - the process instance UUID that identify the instance to suspend.

Throws:

InstanceNotFoundException - thrown if the given instance to suspend is not found.

remove

boolean remove(ProcessInstanceUUID processInstanceUUID)

To delete monitoring information on the process instance.

Parameters:

processInstanceUUID - the process instance UUID that identify the instance to suspend.

Returns:

true if the instance has been successfully deleted otherwise returns false.

findJobsWithException

java.util.List<JobData> findJobsWithException()

Get the list of asynchronous executions for which all the tries have failed and which will not be executed any more.

retryJob

void retryJob(JobData job,
            int retries)
              throws JobNotFoundException

Parameters:

job - the job to retry.

retries - the number of retries to set for the job.

Throws:

JobNotFoundException - if job does not exist.

getPendingMessages

Get the list of messages received by the engine but not yet associated with any execution.

Returns:

removePendingMessage

void removePendingMessage(PendingMessageData message)

Remove the message from the list of messages received by the engine but not yet associated with any execution.
