Class IndexingSPInstruction

java.lang.Object

org.apache.sysml.runtime.instructions.Instruction

org.apache.sysml.runtime.instructions.spark.SPInstruction

org.apache.sysml.runtime.instructions.spark.ComputationSPInstruction

org.apache.sysml.runtime.instructions.spark.UnarySPInstruction

org.apache.sysml.runtime.instructions.spark.IndexingSPInstruction

Direct Known Subclasses:

FrameIndexingSPInstruction, MatrixIndexingSPInstruction

public abstract class IndexingSPInstruction
extends UnarySPInstruction

This class implements the matrix indexing functionality inside Spark. Example instructions: rangeReIndex:mVar1:Var2:Var3:Var4:Var5:mVar6 input=mVar1, output=mVar6, bounds = (Var2,Var3,Var4,Var5) rowindex_lower: Var2, rowindex_upper: Var3 colindex_lower: Var4, colindex_upper: Var5 leftIndex:mVar1:mVar2:Var3:Var4:Var5:Var6:mVar7 triggered by "mVar1[Var3:Var4, Var5:Var6] = mVar2" the result is stored in mVar7
