Class NgramsForOrderMapWrapper<W,V>

java.lang.Object

java.util.AbstractMap<java.util.List<W>,V>

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

Type Parameters:

W -

V -

All Implemented Interfaces:

java.util.Map<java.util.List<W>,V>

public class NgramsForOrderMapWrapper<W,V>
extends java.util.AbstractMap<java.util.List<W>,V>

Wraps an NgramMap as a Java Map, but only ngrams of a particular order. This collection is read-only. It is also uses a lot inefficient boxing and unboxing.
