doEquals

protected boolean doEquals(WeightBuilder functionBuilder)

Description copied from class: ScoreFunctionBuilder

Check that two instances of the same subclass of ScoreFunctionBuilder are equal. Implementers don't need to check any fields in ScoreFunctionBuilder, just fields that they define.

Specified by:

doEquals in class ScoreFunctionBuilder<WeightBuilder>

doHashCode

protected int doHashCode()

Description copied from class: ScoreFunctionBuilder

Hashcode for fields defined in this subclass of ScoreFunctionBuilder. Implementers should ignore fields defined in ScoreFunctionBuilder because they will already be in the hashCode.

Specified by:

doHashCode in class ScoreFunctionBuilder<WeightBuilder>

                              throws java.io.IOException

Description copied from class: ScoreFunctionBuilder

Build the Lucene ScoreFunction for this builder. Implementers should ignore things defined in ScoreFunctionBuilder like weight as they will be handled by the function that calls this one.

Specified by:

doToFunction in class ScoreFunctionBuilder<WeightBuilder>

Throws:

java.io.IOException
