Method Detail

initialize

public void initialize(java.lang.String id,
                       java.lang.Integer value,
                       java.lang.Iterable<DefaultEdge> edges)

Description copied from interface: Vertex

Initialize id, value, and edges. This method (or the alternative form initialize(id, value)) must be called after instantiation, unless readFields() is called.

Specified by:

initialize in interface Vertex<java.lang.String,java.lang.Integer,DefaultEdge>

Parameters:

id - Vertex id

value - Vertex value

edges - Iterable of edges

initialize

public void initialize(java.lang.String id,
                       java.lang.Integer value)

Description copied from interface: Vertex

Initialize id and value. Vertex edges will be empty. This method (or the alternative form initialize(id, value, edges)) must be called after instantiation, unless readFields() is called.

Specified by:

initialize in interface Vertex<java.lang.String,java.lang.Integer,DefaultEdge>

Parameters:

id - Vertex id

value - Vertex value

getId

public java.lang.String getId()

Description copied from interface: Vertex

Get the vertex id.

Specified by:

getId in interface Vertex<java.lang.String,java.lang.Integer,DefaultEdge>

Returns:

My vertex id.

getValue

public java.lang.Integer getValue()

Description copied from interface: Vertex

Get the vertex value (data stored with vertex)

Specified by:

getValue in interface Vertex<java.lang.String,java.lang.Integer,DefaultEdge>

Returns:

Vertex value

setValue

public void setValue(java.lang.Integer value)

Description copied from interface: Vertex

Set the vertex data (immediately visible in the computation)

Specified by:

setValue in interface Vertex<java.lang.String,java.lang.Integer,DefaultEdge>

Parameters:

value - Vertex data to be set

getNumEdges

public int getNumEdges()

Description copied from interface: Vertex

Get the number of outgoing edges on this vertex.

Specified by:

getNumEdges in interface Vertex<java.lang.String,java.lang.Integer,DefaultEdge>

Returns:

the total number of outbound edges from this vertex

getEdges

public java.lang.Iterable<DefaultEdge> getEdges()

Description copied from interface: Vertex

Get a read-only view of the out-edges of this vertex. Note: edge objects returned by this iterable may be invalidated as soon as the next element is requested. Thus, keeping a reference to an edge almost always leads to undesired behavior. Accessing the edges with other methods (e.g., addEdge()) during iteration leads to undefined behavior.

Specified by:

getEdges in interface Vertex<java.lang.String,java.lang.Integer,DefaultEdge>

Returns:

the out edges (sort order determined by subclass implementation).

setEdges

public void setEdges(java.lang.Iterable<DefaultEdge> edges)

Description copied from interface: Vertex

Set the outgoing edges for this vertex.

Specified by:

setEdges in interface Vertex<java.lang.String,java.lang.Integer,DefaultEdge>

Parameters:

edges - Iterable of edges

getEdgeValue

public java.lang.Integer getEdgeValue(java.lang.String targetVertexId)

Description copied from interface: Vertex

Return the value of the first edge with the given target vertex id, or null if there is no such edge. Note: edge value objects returned by this method may be invalidated by the next call. Thus, keeping a reference to an edge value almost always leads to undesired behavior.

Specified by:

getEdgeValue in interface Vertex<java.lang.String,java.lang.Integer,DefaultEdge>

Parameters:

targetVertexId - Target vertex id

Returns:

Edge value (or null if missing)

setEdgeValue

public void setEdgeValue(java.lang.String targetVertexId,
                         java.lang.Integer edgeValue)

Description copied from interface: Vertex

If an edge to the target vertex exists, set it to the given edge value. This only makes sense with strict graphs.

Specified by:

setEdgeValue in interface Vertex<java.lang.String,java.lang.Integer,DefaultEdge>

Parameters:

targetVertexId - Target vertex id

edgeValue - Edge value

addEdge

public void addEdge(DefaultEdge edge)

Description copied from interface: Vertex

Add an edge for this vertex (happens immediately)

Specified by:

addEdge in interface Vertex<java.lang.String,java.lang.Integer,DefaultEdge>

Parameters:

edge - Edge to add

removeEdges

public void removeEdges(java.lang.String targetVertexId)

Description copied from interface: Vertex

Removes all edges pointing to the given vertex id.

Specified by:

removeEdges in interface Vertex<java.lang.String,java.lang.Integer,DefaultEdge>

Parameters:

targetVertexId - the target vertex id
