Class GraphBuilder<V,E,G extends Graph<V,E>>

java.lang.Object

org.jgrapht.graph.builder.AbstractGraphBuilder<V,E,G,GraphBuilder<V,E,G>>

org.jgrapht.graph.builder.GraphBuilder<V,E,G>

Type Parameters:

V - the graph vertex type

E - the graph edge type

G - type of the resulting graph

public class GraphBuilder<V,E,G extends Graph<V,E>>
extends AbstractGraphBuilder<V,E,G,GraphBuilder<V,E,G>>

A builder class for Graph. This is a helper class which helps adding vertices and edges into an already constructed graph instance.

Each graph implementation contains a static helper method for the construction of such a builder. For example class DefaultDirectedGraph contains method DefaultDirectedGraph.createBuilder(EdgeFactory).

See GraphTypeBuilder for a builder of the actual graph instance.

Constructor Detail

GraphBuilder

public GraphBuilder(G baseGraph)

Creates a builder based on baseGraph. baseGraph must be mutable.

The recommended way to use this constructor is: new GraphBuilderBase<...>(new YourGraph<...>(...)).

NOTE: baseGraph should not be an existing graph. If you want to add an existing graph to the graph being built, you should use the AbstractGraphBuilder.addVertex(Object) method.

Parameters:

baseGraph - the graph object to base building on

Method Detail

self

protected GraphBuilder<V,E,G> self()

Specified by:

self in class AbstractGraphBuilder<V,E,G extends Graph<V,E>,GraphBuilder<V,E,G extends Graph<V,E>>>

Returns:

the this object.
