    • getIndexWord

      public IndexWord getIndexWord(POS pos, String lemma)
      Description copied from class: Dictionary
      Look up a word in the database. The search is case-independent, and phrases are separated by spaces ("look up", not "look_up"). Note: this method does not subject lemma to any morphological processing. If you want this, use Dictionary.lookupIndexWord(POS, String).
      Specified by:
      getIndexWord in class Dictionary
      Parameters:
      pos - The part-of-speech.
      lemma - The orthographic representation of the word.
      Returns:
      An IndexWord representing the word, or null if no such entry exists.

    • getIndexWordIterator

      public Iterator getIndexWordIterator(POS pos, String substring)

      Specified by:
      getIndexWordIterator in class Dictionary
      Parameters:
      pos - The part-of-speech.
      Returns:
      An iterator over IndexWords.

    • getIndexWordIterator

      public Iterator getIndexWordIterator(POS pos)
