Class PreferenceMemento


  • public class PreferenceMemento
    extends Object
    A utility to change and remember preference values and later restore there original value. The first time a preference value is changed its current value is stored. Later you can reset all preference values (which are changed through this class) to the state they had when creating the memento.

    This class is most useful for testing to prevent leakage of preference changes between individual tests.
