Class PreferenceChangeEvent

java.lang.Object
org.eclipse.handly.ui.preference.PreferenceChangeEvent
public final class PreferenceChangeEvent extends Object
Describes a change in the value of a preference.

Note: The type of the old and new values of the preference in a PreferenceChangeEvent is determined by whether or not the change was made via the typed preference API. If the value of a preference was changed via the typed API (e.g., via IBooleanPreference), the values in the PreferenceChangeEvent will be of the appropriate specific type. If a non-typed API was used (e.g., OSGi Preferences), the values will be unconverted Strings.
