TimeoutSync

Class TimeoutSync

public class TimeoutSync extends Object implements Sync

A TimeoutSync is an adaptor class that transforms all calls to acquire to instead invoke attempt with a predetermined timeout value.

Sample Usage. A TimeoutSync can be used to obtain Timeouts for locks used in SyncCollections. For example:

 Mutex lock = new Mutex();
 TimeoutSync timedLock = new TimeoutSync(lock, 1000); // 1 sec timeouts
 Set set = new SyncSet(new HashSet(), timedlock);
 try {
   set. add("hi");
 }
 // SyncSets translate timeouts and other lock failures 
 //   to unsupported operation exceptions, 
 catch (UnsupportedOperationException ex) {
    System.out.println("Lock failure");
 }
