de.jungblut.writable

Class VectorWritable

java.lang.Object

de.jungblut.writable.VectorWritable

All Implemented Interfaces:

Comparable<VectorWritable>, org.apache.hadoop.io.Writable, org.apache.hadoop.io.WritableComparable<VectorWritable>

public final class VectorWritable
extends Object
implements org.apache.hadoop.io.WritableComparable<VectorWritable>

New and updated VectorWritable class that has all the other fancy combinations of vectors that are possible in my math library.
This class is not compatible to the one in the clustering package that has a totally different byte alignment in binary files.
