Class SortedProperties

java.util.Dictionary<K,V>

java.util.Hashtable<java.lang.Object,java.lang.Object>

java.util.Properties

org.eclipse.core.internal.preferences.SortedProperties

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, java.util.Map<java.lang.Object,java.lang.Object>

public class SortedProperties
extends java.util.Properties

A Properties class whose entries are sorted by key; can only be used in limited scenarios like storing properties to a file.

Implementation note: The implementations of the keys() and entrySet() methods violate the contracts of Hashtable.keySet() and Hashtable.entrySet(), because the returned sets are not backed by this map. Overriding both methods is necessary to support Oracle and IBM VMS, see bug 325000.
