Package edu.berkeley.nlp.lm.map

Class NgramMapWrapper<W,​V>

  • Type Parameters:
    W -
    V -
    All Implemented Interfaces:
    java.util.Map<java.util.List<W>,​V>
    public class NgramMapWrapper<W,​V>
extends java.util.AbstractMap<java.util.List<W>,​V>
    Wraps an NgramMap as a Java Map, with ngrams of all orders mixed together. This collection is read-only. It is also uses a lot inefficient boxing and unboxing.
