Interface SettableDecoration<K,V>

All Superinterfaces:
Decoration<K,V>
All Known Subinterfaces:
SettableBidiDecoration<K,V>

public interface SettableDecoration<K,V>
extends Decoration<K,V>

An interface for readable and writeable decorations of arbitrary elements. (This is a generalization of interfaces such as NumberEdgeValue in the JUNG 1.x libraries.) Does not place any constraints on the uniqueness of decorations; if you want a one-to-one mapping from elements to decorations, see BidiDecoration or SettableBidiDecoration.

The purpose of this interface is to provide a simple unifying mechanism for accessing element (meta)data, which may be variously stored in instance fields, auxiliary data structures such as Map instances, or the JUNG user data repository.

This interface is designed so as to be compatible with the Map interface--that is, so that a Map instance can serve as a SettableDecoration.

Examples of ways to instantiate this interface include:

 SettableDecoration vertex_stringer = new HashMap();
 SettableDecoration edge_weight = 
      new Decoration() 
      {
          public Integer get(MyEdge e) { return e.getWeight(); }
          public void put(MyEdge e, Integer i) { e.setWeight(i); }
      };
 
(The second example assumes that you have defined a class called MyEdge that provides getWeight() and setWeight methods.)
