Interface GraphElementResolver

Interface for classes that can resolve graph elements based on their GraphML id attribute(s).

Method Summary
`Edge`	`resolveEdge(GraphMLParseContext context, java.lang.String id)` Resolve the GraphML `id` to an `Edge` instance.
`Graph`	`resolveGraph(GraphMLParseContext context, java.lang.String id)` Resolve the GraphML `id` to an `Graph` instance.
`Node`	`resolveNode(GraphMLParseContext context, java.lang.String id)` Resolve the GraphML `id` to an `Node` instance.
`Port`	`resolvePort(GraphMLParseContext context, java.lang.String ownerId, java.lang.String name)` Resolve the GraphML `id` to an `Port` instance.

Method Detail

Node resolveNode(GraphMLParseContext context,
                 java.lang.String id)

Resolve the GraphML id to an Node instance.

Parameters:: context - The current parse context.; id - The id that should be resolved.
Returns:: The Node that is defined by this GraphML id, or null if no such node exists yet.

Graph resolveGraph(GraphMLParseContext context,
                   java.lang.String id)

Resolve the GraphML id to an Graph instance.

Parameters:: context - The current parse context.; id - The id that should be resolved.
Returns:: The Graph that is defined by this GraphML id, or null if no such graph exists yet.

Port resolvePort(GraphMLParseContext context,
                 java.lang.String ownerId,
                 java.lang.String name)

Resolve the GraphML id to an Port instance. The port owner is specified by the ownerId attribute.

The ownerId is required since port names are only locally unique.

Parameters:: context - The current parse context.; ownerId - The GraphML id of the port owner.; name - The id that should be resolved.
Returns:: The Port that is defined by the GraphML ids, or null if no such port exists yet.

Edge resolveEdge(GraphMLParseContext context,
                 java.lang.String id)

Resolve the GraphML id to an Edge instance.

Parameters:: context - The current parse context.; id - The id that should be resolved.
Returns:: The Edge that is defined by this GraphML id, or null if no such edge exists yet.
