Interface BooleanLock

All Known Implementing Classes:

public interface BooleanLock
extends Serializable

This utility can be used to provide an interruptible technique for providing exclusive access to a block of code. It provides a encapsulation of a boolean variable that is easily and safely accessed from multible threads. These threads can set and test the internal value and wait for it to change. The wait/notify mechanism is used internally to support waiting for the value to change, and frees extrenal classes from the errorprone complexity of properly implementing this mechanism.
