ResultLock<T>

Overview

This class represents wait lock that allows to block current thread until signal is received and return result from that thread.

Use case

You can use this class to wait for different actions to complete

var threadLock := new ResultLock<Boolean>;

async begin
  //perform action on another thread
  threadLock.Signal(true);
end;

//block current thread and wait for other thread to send a signal.
threadLock.WaitFor;
writeLn(threadLock.Result);
