All Implemented Interfaces:

LineageTraceable

public final class MatrixIndexingCPFileInstruction
extends IndexingCPInstruction

This instruction is used if a single partition is too large to fit in memory. Hence, the partition is not read but we just return a new matrix with the respective partition file name. For this reason this is a no-op but due to the requirement for direct partition access only applicable for ROWWISE and COLWISE partition formats.
