Class PojoObservables

java.lang.Object
  extended by org.eclipse.core.databinding.beans.PojoObservables

public final class PojoObservables
extends Object

A factory for creating observable objects for POJOs (plain old java objects) that conform to idea of an object with getters and setters but does not provide property change events on change. This factory is identical to BeansObservables except for this fact.
