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

getOp

public Types.OpOpN getOp()

getInstructions

public String getInstructions(String[] inputs,
                              String output)

Generate the complete instruction string for this Lop. This instruction string can have a variable number of input operands. It displays the following:

• Execution type (CP, SPARK, etc.)
• Operand delimiter (°)
• Opcode (printf, etc.)
• Operand delimiter (°)
• Variable number of inputs, each followed by an operand delimiter (°)
  • Input consists of (label · data type · value type · is literal)
• Output consisting of (label · data type · value type)

Example:
The following DML
print('hello %s', 'world')
generates the instruction string:
CP°printf°hello %s·SCALAR·STRING·true°world·SCALAR·STRING·true°_Var1·SCALAR·STRING
