Class StructuredProperties

java.lang.Object
  java.util.Dictionary<K,V>
      java.util.Hashtable<java.lang.Object,java.lang.Object>
          java.util.Properties

All Implemented Interfaces:

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

public class StructuredProperties
extends java.util.Properties

allows structured access to data in java.util.Properties. see main test method for usage example.

note: order is not maintained (todo: move to SortedMap and allow sorting).

note: "defaults" behavior is not maintained in sub-maps.
