Interface AttributedIndexedDirectedGraph<V,A>

Type Parameters:
V - the vertex data type
A - the arrow data type
All Superinterfaces:
IndexedDirectedGraph
All Known Subinterfaces:
AttributedIndexedBidiGraph<V,A>
All Known Implementing Classes:
ImmutableAttributed16BitIndexedDirectedGraph, ImmutableAttributed32BitIndexedBidiGraph, ImmutableAttributed32BitIndexedDirectedGraph, SimpleMutableDirectedGraph
public interface AttributedIndexedDirectedGraph<V,A> extends IndexedDirectedGraph
This interface provides read-only indexed access to a directed graph G = (V, A) with vertex and arrow attributes of the generic types V and A.
  • G is a tuple (V, A) .
  • V is the set of vertices with elements v_i ∈ V. i ∈ {0, ..., vertexCount - 1} .
  • A is the set of ordered pairs with elements (v_i, v_j)_k ∈ A. i,j ∈ {0, ..., vertexCount - 1}. k ∈ {0, ..., arrowCount - 1} .

This interface provides access to the following data in addition to the interface IndexedDirectedGraph:

  • The vertex v_i ∈ V .
  • The arrow a_k ∈ A.
  • The arrow a_(i,j) ∈ A.
