Method Detail

getType

public Instruction.IType getType()

Specified by:

getType in class Instruction

getCPInstructionType

public CPInstruction.CPType getCPInstructionType()

requiresLabelUpdate

public boolean requiresLabelUpdate()

Overrides:

requiresLabelUpdate in class Instruction

getGraphString

public String getGraphString()

Overrides:

getGraphString in class Instruction

preprocessInstruction

public Instruction preprocessInstruction(ExecutionContext ec)

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

processInstruction

public abstract void processInstruction(ExecutionContext ec)

Description copied from class: Instruction

This method should be used to execute the instruction.

Specified by:

processInstruction in class Instruction

Parameters:

ec - execution context

postprocessInstruction

public void postprocessInstruction(ExecutionContext ec)

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

updateLabels

public static String updateLabels(String instList,
                                  LocalVariableMap labelValueMapping)

Takes a delimited string of instructions, and replaces ALL placeholder labels (such as ##mVar2## and ##Var5##) in ALL instructions.

Parameters:

instList - instruction list as string

labelValueMapping - local variable map

Returns:

instruction list after replacement
