Class RealMatrixElementOperations

java.lang.Object
  edu.uci.ics.jung.algorithms.RealMatrixElementOperations

All Implemented Interfaces:

MatrixElementOperations

public class RealMatrixElementOperations

extends java.lang.Object

implements MatrixElementOperations

Implements the basic matrix operations on double-precision values. Assumes that the edges have a MutableDouble value.

Constructor Summary

RealMatrixElementOperations(java.lang.String edge_key)

Method Summary

java.lang.Object	computePathData(Edge e1, Edge e2) If either e1 or e2 is null, the Object reference returned should be null.
void	mergePaths(Edge e, java.lang.Object pathData) If either e or pathData is null, the effect of mergePaths() is implementation-dependent.

Method Detail

mergePaths

public void mergePaths(Edge e,
                       java.lang.Object pathData)

Description copied from interface: MatrixElementOperations

If either e or pathData is null, the effect of mergePaths() is implementation-dependent.

Specified by:

mergePaths in interface MatrixElementOperations

Parameters:

e - (possibly) existing edge in the output graph which represents a path in the input graph(s)

pathData - data (which represents another path with the same source and destination as e in the input graphs) which is to be merged into e

computePathData

public java.lang.Object computePathData(Edge e1,
                                        Edge e2)

Description copied from interface: MatrixElementOperations

If either e1 or e2 is null, the Object reference returned should be null.

Specified by:

computePathData in interface MatrixElementOperations

Parameters:

e1 - first edge from 2-edge path in input graph(s)

e2 - second edge from 2-edge path in input graph(s)

Returns:

aggregation of data from the edges of the 2-edge path (from source of e1 to destination of e2) comprised of (e1, e2)
