Method Details

computeRedirections

public void computeRedirections(Chunk<Values> leftStamps,
 Chunk<Values> rightStamps,
 LongChunk<RowKeys> rightKeyIndices,
 WritableLongChunk<RowKeys> leftRedirections)

Description copied from interface: StampKernel

Stamps the left-hand-side values with the corresponding right hand side.

The rightKeyIndices are parallel to the stamp values in rightStamps; and used to compute a new chunk of redirections parallel to leftStamps.

Specified by:

computeRedirections in interface StampKernel

Parameters:

leftStamps - the input lhs stamp values

rightStamps - the input rhs stamp values

rightKeyIndices - the input rhs stamp indices

leftRedirections - the resulting redirections from the stamping operation
