Package net.sf.ehcache.constructs.blocking Description

Doug Lea in his book Concurrent Programming in Java talks about concurrency support constructs. One meaning of a construct is "an abstract or general idea inferred or derived from specific instances". Just like patterns emerge from noting the similarities of problems and gradually finding a solution to classes of them, so to constructs are general solutions to commond problems. With the constructs package, concrete, extensible implementations are offered to solve these common problems.
