Method Details

computeRedirections

public void computeRedirections(Chunk<Attributes.Values> leftStamps, Chunk<Attributes.Values> rightStamps, LongChunk<Attributes.KeyIndices> rightKeyIndices, WritableLongChunk<Attributes.KeyIndices> 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
