BasicGraphModel

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.

Constructor Detail

BasicModularGraphModel

public BasicModularGraphModel(Graph root)

Construct an empty graph model whose root is the given semantic object.

Method Detail

getCompositeModel

public CompositeModel getCompositeModel(java.lang.Object composite)

Return the model for the given composite object. If the object is not a composite, meaning that it does not contain other nodes, then return null.

Specified by:

getEdgeModel

public EdgeModel getEdgeModel(java.lang.Object edge)

Return the model for the given edge object. If the object is not an edge, then return null.

Specified by:

getEdgeModel in class ModularGraphModel

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

public java.lang.Object getProperty(java.lang.Object o,
                                    java.lang.String propertyName)

Return the property of the object associated with the given property name.

Specified by:
