Examples of ptolemy.kernel.util.Workspace.wait()

ptolemy.kernel.util.Workspace.wait()
Release all the read accesses held by the current thread and suspend the thread by calling Object.wait() on the specified object. When the call returns, re-acquire all the read accesses held earlier by the thread and return. If the calling thread is interrupted while waiting to re-acquire read accesses, an InternalErrorException is thrown, and the thread no longer has read access to the workspace. This method helps prevent deadlocks caused when a thread that waits for another thread to do something prevents it from doing that something by holding read access on the workspace. @param obj The object that the thread wants to wait on. @exception InterruptedException If the calling thread is interruptedwhile waiting on the specified object and all the read accesses held earlier by the thread are re-acquired. @exception InternalErrorException If re-acquiring the read accessesheld earlier by the thread fails.
