createControl

public void createControl(Composite parent,
                          int style)

createEdge

protected Edge createEdge(ILabelProvider labelProvider,
                          java.lang.Object contentSourceNode,
                          Node sourceNode,
                          java.lang.Object contentTargetNode,
                          Node targetNode)

Constructs and returns a new Edge connecting the given sourceNode and targetNode. If the labelProvider implements IGraphNodeLabelProvider, then attributes for the edge are determined using the IGraphNodeLabelProvider.getEdgeAttributes(Object, Object) methods and inserted into the edge.

Parameters:

labelProvider - This viewer's ILabelProvider for convenience.

contentSourceNode - The content element representing the source node of this edge.

sourceNode - The already created source Node of this edge.

contentTargetNode - The content element representing the target node of this edge.

targetNode - The already created target Node of this edge.

Returns:

The new Edge.

createEmptyGraph

protected Graph createEmptyGraph()

Constructs and returns a new Graph and inserts default attributes into it:

1. layout algorithm

Returns:

A new Graph with default attributes.

createModule

protected com.google.inject.Module createModule()

createNestedGraph

protected Graph createNestedGraph(java.lang.Object contentNestingNode,
                                  INestedGraphContentProvider nestedGraphContentProvider,
                                  ILabelProvider labelProvider)

Creates a Graph nested in the node represented by the given contentNestingNode.

Parameters:

contentNestingNode -

nestedGraphContentProvider - This viewer's INestedGraphContentProvider for convenience.

labelProvider - This viewer's ILabelProvider for convenience.

Returns:

The new Graph.

createNode

protected Node createNode(java.lang.Object contentNode,
                          IGraphNodeContentProvider graphContentProvider,
                          ILabelProvider labelProvider)

Creates a Node for the specified contentNode using the IContentProvider and ILabelProvider. Moreover, the new node is put into the given contentToGraphMap.

Parameters:

contentNode -

graphContentProvider - This viewer's IGraphNodeContentProvider for convenience.

labelProvider - This viewer's ILabelProvider for convenience.

Returns:

The new Node.

createNodesAndEdges

protected void createNodesAndEdges(IGraphNodeContentProvider graphContentProvider,
