Method Detail

getValue

public int getValue(java.lang.String word,
                    MRCPoS pos,
                    Field field)
             throws QueryException

Returns an integer feature value from the database.

Parameters:

word - Lemma of the word to look for.

pos - Part-of-Speech of the word.

field - Field of the database providing the value.

Returns:

value.

Throws:

QueryException - if the word/PoS/Field isn't found, or if the value is undefined (e.g. 0 value for some fields).

getValue

public int getValue(java.lang.String word,

Returns an integer feature value from the database.

Parameters:

word - Lemma of the word to look for.

pos - String representation of the Part-of-Speech of the word.

field - Field of the database providing the value.

Returns:

value.

Throws:

QueryException - if the word/PoS/Field isn't found, or if the value is undefined (e.g. 0 value for some fields).

getFields

public java.util.List<Field> getFields()

Returns all the fields of the MRC database.

Overrides:
