public interface AddVertexI

extends GraphI

An interface implemented by graphs that can add vertices.

SparseGraph

Method Summary
VertexI	addVertex(java.lang.Object key)           Adds a new vertex to the graph with a null value.
VertexI	addVertex(java.lang.Object key, java.lang.Object value)           Adds a new vertex to the graph with a value.
VertexI	addVertex(VertexI vertex)           Adds a new vertex to the graph, the key and value are taken from 'vertex'.
void	ensureVertexCapacity(int vertexCapacity)           Ensures that the graph can efficiently hold this many vertices.

Method Detail

ensureVertexCapacity

public void ensureVertexCapacity(int vertexCapacity)

Ensures that the graph can efficiently hold this many vertices.

addVertex

public VertexI addVertex(java.lang.Object key)
                  throws DuplicateVertexException

Adds a new vertex to the graph with a null value. Throws 'DuplicateVertexException' if the vertex already exists.

addVertex

public VertexI addVertex(java.lang.Object key,
                         java.lang.Object value)
                  throws DuplicateVertexException

Adds a new vertex to the graph with a value. Throws 'DuplicateVertexException' if the vertex already exists.

addVertex

public VertexI addVertex(VertexI vertex)
                  throws DuplicateVertexException

Adds a new vertex to the graph, the key and value are taken from 'vertex'. Throws 'DuplicateVertexException' if the vertex already exists.
