Synchronizer

Instances of this class provide synchronization support for displays. A default instance is created automatically for each display, and this instance is sufficient for almost all applications. IMPORTANT: Typical application code never needs to deal with this class. It is provided only to allow applications which require non-standard synchronization behavior to plug in the support they require. Subclasses which override the methods in this class must ensure that the superclass methods are invoked in their implementations

Functions

addLast void addLast(RunnableLock lock): Undocumented in source. Be warned that the author may not have intended to support it.
asyncExec void asyncExec(Runnable runnable): Causes the <code>run()</code> method of the runnable to be invoked by the user-interface thread at the next reasonable opportunity. The caller of this method continues to run in parallel, and is not notified when the runnable has completed.
getMessageCount int getMessageCount(): Undocumented in source. Be warned that the author may not have intended to support it.
releaseSynchronizer void releaseSynchronizer(): Undocumented in source. Be warned that the author may not have intended to support it.
removeFirst RunnableLock removeFirst(): Undocumented in source. Be warned that the author may not have intended to support it.
runAsyncMessages bool runAsyncMessages(): Undocumented in source. Be warned that the author may not have intended to support it.
runAsyncMessages bool runAsyncMessages(bool all): Undocumented in source. Be warned that the author may not have intended to support it.
syncExec void syncExec(Runnable runnable): Causes the <code>run()</code> method of the runnable to be invoked by the user-interface thread at the next reasonable opportunity. The thread which calls this method is suspended until the runnable completes.
