Method Detail

generateGraph

void generateGraph(Graph<V,E> target,
                   Map<String,T> resultMap)

Generate a graph structure. The topology of the generated graph is dependent on the implementation. For graphs in which not all vertices share the same automorphism equivalence class, the generator may produce a labeling indicating the roles played by generated elements. This is the purpose of the resultMap parameter. For example, a generator for a wheel graph would designate a hub vertex. Role names used as keys in resultMap should be declared as public static final Strings by implementation classes.

Parameters:

target - receives the generated edges and vertices; if this is non-empty on entry, the result will be a disconnected graph since generated elements will not be connected to existing elements

resultMap - if non-null, receives implementation-specific mappings from String roles to graph elements (or collections of graph elements)

Throws:

UnsupportedOperationException - if the graph does not have appropriate vertex and edge suppliers, in order to be able to create new vertices and edges. Methods Graph.getEdgeSupplier() and Graph.getVertexSupplier() must not return null.

generateGraph

default void generateGraph(Graph<V,E> target)

Generate a graph structure.

Parameters:

target - receives the generated edges and vertices; if this is non-empty on entry, the result will be a disconnected graph since generated elements will not be connected to existing elements

Throws:

UnsupportedOperationException - if the graph does not have appropriate vertex and edge suppliers, in order to be able to create new vertices and edges
