Class Monitor

java.lang.Object
  nl.tudelft.simulation.language.concurrent.Monitor

public final class Monitor
extends java.lang.Object

In the Java programming language there is a lock associated with every object. The language does not provide a way to perform separate lock and unlock operations; instead, they are implicitly performed by high-level constructs that always arrange to pair such operations correctly. This Monitor class, however, provides separate monitorenter and monitorexit instructions that implement the lock and unlock operations.)
