edu.umass.cs.mallet.base.pipe.iterator

Class InstanceListIterator

java.lang.Object

edu.umass.cs.mallet.base.pipe.iterator.AbstractPipeInputIterator

edu.umass.cs.mallet.base.pipe.iterator.InstanceListIterator

All Implemented Interfaces:

PipeInputIterator, Iterator

public class InstanceListIterator
extends AbstractPipeInputIterator

This method feeds a pipeline from another InstanceList. The new instances will have their pipe set to the pipe this iterates into, and will carry no record of their previous origin. New instance objects will be created; the originals are not modified.

This must be used with caution, for it can result in accidentally piping the same instances through the same pipe twice, something that MALLET otherwise tries to protect you from.

To save memory, in the future we might add a flag that (if set) would cause this to remove the original instances from the InstanceList.
