package org.apache.lucene.analysis.morph
Abstract classes for morphological analyzers.

- Class
  Description
  BinaryDictionary<T extends MorphData>
  Abstract dictionary base class.
  BinaryDictionaryWriter<T extends BinaryDictionary<? extends MorphData>>
  Abstract base dictionary writer class.
  CharacterDefinition
  Character category data.
  CharacterDefinition.LookupCharacterClass
  Functional interface to lookup character class
  CharacterDefinitionWriter<T extends CharacterDefinition>
  Writes character definition file
  ConnectionCosts
  n-gram connection cost data
  ConnectionCostsWriter<T extends ConnectionCosts>
  Writes connection costs
  Dictionary<T extends MorphData>
  High-level dictionary interface for morphological analyzers.
  DictionaryEntryWriter
  Abstract writer class to write dictionary entries.
  GraphvizFormatter<T extends MorphData>
  Outputs the dot (graphviz) string for the viterbi lattice.
  GraphvizFormatter.DictionaryProvider<T extends MorphData>
  `Dictionary` provider
  MorphData
  High-level interface that represents morphological information in a dictionary
  Token
  Analyzed token with morphological data.
  TokenInfoFST
  Thin wrapper around an FST with root-arc caching.
  TokenType
  Token type reflecting the original source of this token
  Viterbi<T extends Token,U extends Viterbi.Position>
  Performs Viterbi algorithm for morphological Tokenizers, which split texts by Hidden Markov Model or Conditional Random Fields.
  Viterbi.Position
  Holds all back pointers arriving to this position.
  Viterbi.WrappedPositionArray<U extends Viterbi.Position>
  Holds partial graph (array of positions) for calculating the minimum cost path
  ViterbiNBest<T extends Token,U extends MorphData>
  `Viterbi` subclass for n-best path calculation.
  ViterbiNBest.Lattice<U extends MorphData>
  Yet another lattice data structure for keeping n-best path.
  ViterbiNBest.PositionNBest
  `Viterbi.Position` extension; this holds all forward pointers to calculate n-best path.
