Class NodeFactory

java.lang.Object

cern.gp.nodes.NodeFactory

public class NodeFactory
extends java.lang.Object

This factory can be used to build a node representing a given bean. The node will extract the information it needs directly from the bean. As nodes are used to build up a hierarchy of objects (a node having children that can also have children) and as beans don't carry the concept of a hierarchy, it is possible to specify the children of the node representing a given bean by passing a ChildrenManager.

Example of creating a node with children

 GPNode node = NodeFactory.createNode(equipmentBean, new EquipmentChildrenListManager(euipmentBean));
 

Example of creating a node without children

 GPNode leaf = NodeFactory.createNode(equipmentBean);
