Method Detail

aggregate

public void aggregate(AbstractKeyArrayIndexProcedure.ResultBitBuffer result,
                      Split split)

Description copied from interface: IResultHandler

Method is invoked for each result and is responsible for combining the results in whatever manner is meaningful for the procedure. Implementations of this method MUST be thread-safe since the procedure MAY be applied in parallel when it spans more than one index partition.

Specified by:

aggregate in interface IResultHandler<AbstractKeyArrayIndexProcedure.ResultBitBuffer,Long>

Parameters:

result - The result from applying the procedure to a single index partition.

split - The Split that generated that result.

getResult

public Long getResult()

The #of true values observed in the aggregated AbstractKeyArrayIndexProcedure.ResultBitBuffers.

Specified by:

getResult in interface IResultHandler<AbstractKeyArrayIndexProcedure.ResultBitBuffer,Long>
