class Ens.BPL.Scope extends Ens.BPL.Activity

This class represents a sequence of activities to be performed. Errors occuring with the scope block are caught and redirected to the a fault handler. The fault handler can, if desired, invoke a compensation handler which is a named block of code which is intended to compensate for the fault. Transfer of control flow to a catch block can also be achieved by using the Throw activity,naming the catch block to be invoked.
