Class SemaphoreResult

java.lang.Object
  com.lts.ipc.semaphore.SemaphoreResult

public class SemaphoreResult
extends java.lang.Object

An internal class that contains the results from a native system call.

Calls to the underlying operation system will often have sever pieces of information instead of just success and failure. This class allows clients to get back all the information at once.

The RESULT_ constants are defined to make life easier for the JNI: accessing enum tags in JNI is somewhat difficult.
