public boolean cancel ();

This method is called by the Aware IM framework when the operator sends the request to cancel the process.

none

The method should return true if it allows the system to cancel the process. In this case it should set an internal flag indicating that the process has been cancelled. The execute and resume methods should periodically check this flag and if its value is true abort the execution of the process (see Examples of custom process components). If a process is in a state that does not allow canceling, the method should return false.
