Interface AttributeConsumer

All Known Implementing Classes:
MatrixView
public interface AttributeConsumer
Interfaces an object, which depends on the presence of a set of attributes. An attribute consumer specifies, which attributes should be available in a node, edge and graph object. Each time, a node or an edge is created, the specified attributes will be created by the graph instance. E.g.: a 2D view depends on some graphics attributes ("graphics") in every node and edge object. It implements this interface and returns a CollectionAttribute of these attributes and their default values: 
 public CollectionAttribute getNodeAttribute() {
        return new NodeGraphicAttribute();
 }
 
 public CollectionAttribute getEdgeAttribute() {
        return new EdgeGraphicAttribute();
 }
Every time, a new node- or edge-object is created, it will contain (deep-)copies of these collection attributes.
