Method Detail

getSPInstructionType

public SPInstruction.SPType getSPInstructionType()

requiresLabelUpdate

public boolean requiresLabelUpdate()

Overrides:

requiresLabelUpdate in class Instruction

getGraphString

public String getGraphString()

Overrides:

getGraphString in class Instruction

preprocessInstruction

public Instruction preprocessInstruction(org.apache.sysml.runtime.controlprogram.context.ExecutionContext ec)
                                  throws DMLRuntimeException

Description copied from class: Instruction

This method should be used for any setup before executing this instruction. Overwriting methods should first call the super method and subsequently do their custom setup.

Overrides:

preprocessInstruction in class Instruction

Parameters:

ec - execution context

Returns:

instruction

Throws:

DMLRuntimeException - if DMLRuntimeException occurs

processInstruction

public abstract void processInstruction(org.apache.sysml.runtime.controlprogram.context.ExecutionContext ec)
                                 throws DMLRuntimeException

Description copied from class: Instruction

This method should be used to execute the instruction.

Specified by:

processInstruction in class Instruction

Parameters:

ec - execution context

Throws:

DMLRuntimeException - if DMLRuntimeException occurs

postprocessInstruction

public void postprocessInstruction(org.apache.sysml.runtime.controlprogram.context.ExecutionContext ec)
                            throws DMLRuntimeException

Description copied from class: Instruction

This method should be used for any tear down after executing this instruction. Overwriting methods should first do their custom tear down and subsequently call the super method.

Overrides:

postprocessInstruction in class Instruction

Parameters:

ec - execution context

Throws:

DMLRuntimeException - if DMLRuntimeException occurs
