public class BasicModularGraphModel

extends MutableModularGraphModel

A modular implementation of the graph model, whereby users with heterogeneous graphs can implement the graph model interface by implementing the simple interfaces of Graph, Node, CompositeNode, and Edge.

getNodeModel

public NodeModel getNodeModel(java.lang.Object node)

Return the node model for the given object. If the object is not a node, then return null.

Specified by:

getNodeModel in class ModularGraphModel

---

getProperty

Return the semantic object corresponding to the given node, edge, or composite.

Specified by:

getSemanticObject in interface GraphModel

Specified by:

getSemanticObject in class ModularGraphModel

---

setProperty

public void setProperty(java.lang.Object o,
 java.lang.String propertyName,
 java.lang.Object value)
