getValues

public DocValues getValues(Map context,
                           IndexReader reader)
                    throws IOException
Description copied from class: ValueSource
Gets the values for this reader and the context that was previously passed to createWeight()

Overrides:
getValues in class ValueSource
Throws:
IOException

createWeight

public void createWeight(Map context,
                         Searcher searcher)
                  throws IOException
Description copied from class: ValueSource

Overrides:
createWeight in class ValueSource
Throws:
IOException

hashCode

public int hashCode()
Specified by:
hashCode in class ValueSource

equals

public boolean equals(Object o)
