Workflow API¶

cloudify.workflows.workflow_api.has_cancel_request()[source]¶

Checks for requests to cancel the workflow execution. This should be used to allow graceful termination of workflow executions.

If this method is not used and acted upon, a simple ‘cancel’ request for the execution will have no effect - ‘force-cancel’ will have to be used to abruptly terminate the execution instead.

Note: When using this method, the workflow must return EXECUTION_CANCELLED_RESULT if indeed the execution gets cancelled.

Returns:	whether there was a request to cancel the workflow execution

exception cloudify.workflows.workflow_api.ExecutionCancelled[source]¶

Bases: exceptions.Exception

Raised by the workflow engine when the workflow was cancelled during a blocking call to some workflow task’s task.get()
