Class IntDoublePairWritable

java.lang.Object

org.apache.mahout.clustering.spectral.IntDoublePairWritable

All Implemented Interfaces:

org.apache.hadoop.io.Writable

public class IntDoublePairWritable
extends Object
implements org.apache.hadoop.io.Writable

This class is a Writable implementation of the mahout.common.Pair generic class. Since the generic types would also themselves have to implement Writable, it made more sense to create a more specialized version of the class altogether. In essence, this can be treated as a single Vector Element.
