Class Latch

java.lang.Object

com.oracle.svm.core.genscavenge.Latch

All Implemented Interfaces:

AutoCloseable

public class Latch
extends Object
implements AutoCloseable

An AutoCloseable boolean. A Latch can be used in

 try (final Latch i = myLatch.open()) {
     ....
 }
 

or it can be used without the "try" if you do not want it to be auto-closed, as in

 myLatch.open();
 ....
 myLatch.close();
 

so that exceptions coming out of the .... will not close the Latch.
