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,AbstractKeyArrayIndexProcedure.ResultBitBuffer>

Parameters:

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

split - The Split that generated that result.

getResult

public AbstractKeyArrayIndexProcedure.ResultBitBuffer getResult()

The aggregated results.

Specified by:

getResult in interface IResultHandler<AbstractKeyArrayIndexProcedure.ResultBitBuffer,AbstractKeyArrayIndexProcedure.ResultBitBuffer>
