Class UnlabeledFileIterator

java.lang.Object

cc.mallet.pipe.iterator.UnlabeledFileIterator

All Implemented Interfaces:

java.util.Iterator<Instance>

public class UnlabeledFileIterator
extends java.lang.Object
implements java.util.Iterator<Instance>

An iterator that generates instances from an initial directory or set of directories. The iterator will recurse through sub-directories. Each filename becomes the data field of an instance, and the targets are set to null. To set the target values to the directory name, use FileIterator instead.
