Class: ezcWorkflowVisitorVerification

An implementation of the ezcWorkflowVisitor interface that verifies a workflow specification. [source]
This visitor should not be used directly but will be used by the verify() method on the workflow.

 2.  $workflow->verify();
 3.  ?>
The verifier checks that:
  • there is only one start node
