Method Detail

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

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

getOperationType

public Types.OpOp2 getOperationType()

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
