java.lang.Object
  info.aduna.language.identification.ngram.NGram

All Implemented Interfaces:

Comparable<NGram>

public class NGram
extends Object
implements Comparable<NGram>

A simple, straightforward n-gram implementation. This NGram has an additional field for capturing the number of occurrences of an ngram. This field is optional and completely ignored by the equals and hashCode methods.

Constructor Summary

NGram(char[] chars, int start, int length, int count)

Method Summary

int	compareTo(NGram other)
boolean	equals(char[] chars, int start, int length)
boolean	equals(Object object)
int	getCount() Returns the number of occurrences of this NGram, or a negative value when the count is not used.
int	hashCode()
static int	hashCode(char[] chars, int start, int length) Create a hash code for the specified char sequence.
void	increaseCount() Increase the count with one.
