Method Details

install

public void install(Map params)
             throws JWNLException

Throws:

JWNLException

getIndexWord

public IndexWord getIndexWord(POS pos,
 String lemma)
                       throws JWNLException

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.

Throws:

JWNLException

getIndexWordIterator

public Iterator getIndexWordIterator(POS pos)
                              throws JWNLException

Description copied from class: Dictionary

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

Specified by:

getIndexWordIterator in class Dictionary

Parameters:

pos - The part-of-speech

Returns:

An iterator over IndexWords

Throws:

JWNLException

getIndexWordIterator

public Iterator getIndexWordIterator(POS pos,
 String substring)
                              throws JWNLException

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.

Throws:

JWNLException

getRandomIndexWord

public IndexWord getRandomIndexWord(POS pos)
                             throws JWNLException

Specified by:

getRandomIndexWord in class Dictionary

Throws:

JWNLException

getSynsetAt

public Synset getSynsetAt(POS pos,
 long offset)
                   throws JWNLException

Description copied from class: Dictionary

Return the Synset at offset offset from the database.

Specified by:

getSynsetAt in class Dictionary

Parameters:

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

offset - The offset of the synset in the file

Returns:

A synset containing the parsed line from the database

Throws:

JWNLException

getSynsetIterator

public Iterator getSynsetIterator(POS pos)
                           throws JWNLException

Description copied from class: Dictionary

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

Specified by:

getSynsetIterator in class Dictionary

Parameters:

pos - The part-of-speech.

Returns:

An iterator over Synsets.

Throws:

JWNLException

getException

public Exc getException(POS pos,
 String derivation)
                 throws JWNLException

Returns:

Exc the Exc object

Throws:

JWNLException
