Method Detail

resolveEdge

IEdge resolveEdge(IParseContext context,
                  String id)

Resolve the GraphML id to an IEdge instance.

Parameters:

context - The current parse context.

id - The id that should be resolved.

Returns:

The IEdge that is defined by this GraphML id, or null if no such edge exists yet.

resolveGraph

IGraph resolveGraph(IParseContext context,
                    String id)

Resolve the GraphML id to an IGraph instance.

Parameters:

context - The current parse context.

id - The id that should be resolved.

Returns:

The IGraph that is defined by this GraphML id, or null if no such graph exists yet.

resolveNode

INode resolveNode(IParseContext context,
                  String id)

Resolve the GraphML id to an INode instance.

Parameters:

context - The current parse context.

id - The id that should be resolved.

Returns:

The INode that is defined by this GraphML id, or null if no such node exists yet.

resolvePort

IPort resolvePort(IParseContext context,
                  String ownerId,
                  String id)

Resolve the GraphML id to an IPort instance.

The port owner is specified by the ownerId attribute.

Parameters:

context - The current parse context.

ownerId - The GraphML id of the port owner.

id - The id that should be resolved.

Returns:

The IPort that is defined by the GraphML ids, or null if no such port exists yet.
