Simulation.Aivika.GPSS.TransactQueueStrategy

Description

Tested with: GHC 8.0.2

This module defines a GPSS transact queue strategy.

transactStrategyQueueDeleteBy :: StrategyQueue (TransactQueueStrategy s) a -> Int -> (a -> Bool) -> Event (Maybe a)
transactStrategyQueueContainsBy :: StrategyQueue (TransactQueueStrategy s) a -> Int -> (a -> Bool) -> Event (Maybe a)

transactStrategyQueueDeleteBy Source #

Arguments

:: StrategyQueue (TransactQueueStrategy s) a	the queue
-> Int	the transact priority
-> (a -> Bool)	the predicate
-> Event (Maybe a)

Try to delete the transact by the specified priority and satisfying to the provided predicate.

transactStrategyQueueContainsBy Source #

Arguments

:: StrategyQueue (TransactQueueStrategy s) a	the queue
-> Int	the transact priority
-> (a -> Bool)	the predicate
-> Event (Maybe a)

Test whether the queue contains a transact with the specified priority satisfying the provided predicate.
