Method Detail

install

public void install(java.util.Map params)
             throws JWNLException

Throws:

JWNLException

getIndexWord

public IndexWord getIndexWord(POS pos,
                              java.lang.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 java.util.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

                                        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)

Description copied from class: Dictionary

Return the Synset at offset offset from the database.

Specified by:
