getIndexWord

public IndexWord getIndexWord(POS pos,
                              java.lang.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 java.util.Iterator getIndexWordIterator(POS pos,
                                               java.lang.String substring)

Description copied from class: Dictionary

Return an Iterator over all the IndexWords of part-of-speech pos whose lemmas contain substring as a substring.

Specified by:

getIndexWordIterator in class Dictionary

Parameters:

pos - The part-of-speech.

Returns:

An iterator over IndexWords.

getIndexWordIterator

public java.util.Iterator getIndexWordIterator(POS pos)

Description copied from class: Dictionary

Return an Iterator over all the IndexWords of part-of-speech pos in the database.

Specified by:

Parameters:

pos - The part-of-speech file to look in

offset - The offset of the synset in the file
