readMessageback to summary
public Object readMessage()

Implements sun.jvm.hotspot.utilities.MessageQueue.readMessage.

Doc from sun.jvm.hotspot.utilities.MessageQueue.readMessage.

This blocks until a message is available. Even if the thread is interrupted while it is waiting, this will not return until a message is written by the entity on the other side of the queue.

readMessageWithTimeoutback to summary
public Object readMessageWithTimeout(long millis)

Implements sun.jvm.hotspot.utilities.MessageQueue.readMessageWithTimeout.

Doc from sun.jvm.hotspot.utilities.MessageQueue.readMessageWithTimeout.

This blocks for up to millis milliseconds until a message is available. If no message becomes available within this time period, or the thread is interrupted during the wait, returns null. (This implies that passing the value null back and forth is not distinguishable with this method.) Passing a value of 0 for the millis argument causes this method to return without blocking. The millis argument must be greater than or equal to zero.

public void writeMessage(Object obj)

Implements sun.jvm.hotspot.utilities.MessageQueue.writeMessage.
