Method Detail

getDegree

public LongValue getDegree()

Get the vertex degree.

Returns:

vertex degree

setDegree

public void setDegree(LongValue degree)

Set the vertex degree.

Parameters:

degree - vertex degree

getTriangleCount

public LongValue getTriangleCount()

Get the number of triangles containing this vertex; equivalently, this is the number of edges between neighbors of this vertex.

Returns:

triangle count

setTriangleCount

public void setTriangleCount(LongValue triangleCount)

Set the number of triangles containing this vertex; equivalently, this is the number of edges between neighbors of this vertex.

Parameters:

triangleCount - triangle count

getLocalClusteringCoefficientScore

public double getLocalClusteringCoefficientScore()

Get the local clustering coefficient score. This is computed as the number of edges between neighbors, equal to the triangle count, divided by the number of potential edges between neighbors.

A score of Double.NaN is returned for a vertex with degree 1 for which both the triangle count and number of neighbors are zero.

Returns:

local clustering coefficient score

toString

public String toString()

Description copied from class: ResultBase

Object.toString() must be overridden to write POJO values in the same form as Tuple. Values are comma-separated and enclosed in parenthesis, e.g. "(f0,f1)".

Specified by:

toString in class ResultBase

Returns:

tuple representation string

toPrintableString

public String toPrintableString()

Format values into a human-readable string.

Specified by:

toPrintableString in interface PrintableResult

Returns:

verbose string

hashCode

public int hashCode()

Overrides:

hashCode in class Object
