Specified by:

processActivities in interface IProcessScheduler

Parameters:

activities - Activities to process

Throws:

BPSimulatorException

InterruptedException

checkForEnabledOrJoinActivities

                                            InterruptedException

Checks if completion or suspension of activity enables OR joins and processes the enabled OR joins

Parameters:

fromActivity - activity to check for

Throws:

BPSimulatorException

InterruptedException

setResourceManager
