Description copied from interface: Gate

Determine the next Transition.

This is the key (and sole) method of the gate. By entering this method, the calling process enters the gate. This method must do anything that is necessary to determine the next transition and must then return this transition. It is invalid, to return a null transition, except in the special cases noted below.

The method must be interruptible by calls to Thread.interrupt() on the executing thread and it must propagate these interrupts as a InterruptedException. In this case it is obviously no problem, if the method returns a null transition.

Also, if any other exception causes the method to be left, or in the case of an explicit call to the process' SaleProcess.error(int) method, the result may be null.

Specified by:

getNextTransition in interface Gate

Parameters:

p - the process that entered the gate and triggered the method.

u - the user currently active in the process' ProcessContext

Returns:

the Transition to be performed after leaving the gate.
