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
