Method Details

getActiveTransaction

public Transaction getActiveTransaction()

fireAttributeChanged

public void fireAttributeChanged(Object object,
 boolean asNode,
 Attribute a,
 FieldChain field,
 int[] indices)

Specified by:

fireAttributeChanged in class GraphState

fireEdgeChanged

protected void fireEdgeChanged(Object source,
 Object target,
 Object edge)

Specified by:

fireEdgeChanged in class GraphState

containsInTree

public boolean containsInTree(Object object,
 boolean asNode)

Description copied from class: GraphState

Tests whether an object is contained in the tree of the graph. The tree is defined by Graph.getTreePattern().

Specified by:

containsInTree in class GraphState

Parameters:

object - the object

asNode - true if object is a node, false if object is an edge

Returns:

true iff the object is part of the tree
