YEnabledTransitionSet (YAWL Version 4.3)

```
public class YEnabledTransitionSet
extends java.lang.Object
```
This class collects the set of all currently enabled transitions (ie. tasks) of a net. It is designed to provide a completely correct implementation of the YAWL deferred choice semantics. Enabled transitions are grouped by the id of the enabling place (condition). For each place: if there is one or more composite tasks enabled, one of the composite tasks is chosen (randomly if more than one) and all other tasks are not fired; otherwise, all the atomic tasks are enabled, allowing a choice to be made from the environment, and each atomic task is 'stamped' with an identifier that services may use to identify tasks that are part of the same group. This class is used exclusively by YNetRunner's continueIfPossible() and fireTasks() methods. Author: Michael Adams Date: 5/03/2008
