Method Details

setNumThreads

public void setNumThreads(int k)

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

 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

getInstructions

public String getInstructions(String input1,
 String input2,
 String input3,
 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

input3 - input 3

output - output

Returns:

instructions as string
