Stop any action

Specified by:

stop in interface BeanCommon

Specified by:

stop in class AbstractTrainAndTestSetProducer

block

private void block(boolean tf)

Returns true, if at the current time, the named event could be generated. Assumes that the supplied event name is an event that could be generated by this bean

Specified by:

eventGeneratable in interface EventConstraints

Parameters:

eventName - the name of the event in question

Returns:

true if the named event could be generated at this point in time
