Class NgramIterableWrapper<W,V>

java.lang.Object

edu.berkeley.nlp.lm.map.NgramIterableWrapper<W,V>

Type Parameters:

W -

V -

All Implemented Interfaces:

Iterable<Map.Entry<List<W>,V>>

public class NgramIterableWrapper<W,V>
extends Object
implements Iterable<Map.Entry<List<W>,V>>

Wraps an NgramMap as an Iterable, so it is easy to iterate over the n-grams and associated values. Using this interface is a little inefficient due to the boxing and temporary object allocation necessary to conform to Java's interfaces.
