Class Synchronizer

java.lang.Object
org.eclipse.swt.widgets.Synchronizer
Direct Known Subclasses:
ClusteredSynchronizer
public class Synchronizer extends Object
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
