- the graph vertex typeE
- the graph edge typeG
- 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 forGraph
. 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 methodDefaultDirectedGraph.createBuilder(Supplier)
.See
GraphTypeBuilder
for a builder of the actual graph instance.- Author:

GraphBuilder
public GraphBuilder(G baseGraph)
Creates a builder based onbaseGraph
.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 theAbstractGraphBuilder.addVertex(Object)
method.- Parameters:
baseGraph
- the graph object to base building on
