Class Monitor

java.lang.Object
nl.tudelft.simulation.language.concurrent.Monitor
public final class Monitor extends Object
Monitor class. 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. The class is final for now, as it is not the idea that the class should be extended. It has only static methods.
