MapMult

public MapMult(Lop input1,
               Lop input2,
               Types.DataType dt,
               Types.ValueType vt,
               boolean rightCache,
               boolean partitioned,
               boolean emptyBlocks,
               AggBinaryOp.SparkAggType aggtype)

Constructor to setup a partial Matrix-Vector Multiplication for Spark

Parameters:

input1 - low-level operator 1

input2 - low-level operator 2

dt - data type

vt - value type

rightCache - true if right cache, false if left cache

partitioned - true if partitioned, false if not partitioned

emptyBlocks - true if output empty blocks

aggtype - spark aggregation type

Method Detail

getAggType

public AggBinaryOp.SparkAggType getAggType()

Description copied from class: Lop

Method to get aggregate type if applicable. This method is overridden by the Lops with aggregate types (e.g. MapMult)

Overrides:

getAggType in class Lop

Returns:

SparkAggType

getBroadcastInput

public Lop getBroadcastInput()

Description copied from class: Lop

Method to get the input to be broadcast. This method is overridden by the Lops which require broadcasts (e.g. AppendM)

Overrides:

getBroadcastInput in class Lop

Returns:

An input Lop or Null

toString

public String toString()

Description copied from class: Lop

Method to have Lops print their state. This is for debugging purposes.

Specified by:

toString in class Lop

getInstructions

public String getInstructions(String input1,
                              String input2,
                              String output)

Description copied from class: Lop

Method should be overridden if needed

Overrides:

getInstructions in class Lop

Parameters:

input1 - input 1

input2 - input 2

output - output

Returns:

instructions as string
