Method Details

setupNextStep

protected void setupNextStep()

Description copied from class: Context

If Context can have next steps (i.e., children), implement this method to add the next child context that should be executed.

Overrides:

setupNextStep in class Context

setupArguments

protected void setupArguments(List<? extends Object> inputArgs,
 List<? extends Object> returnArgs)

Sets up the variable for the "for" context.

Specified by:

setupArguments in class ArgumentBasedContext

Parameters:

inputArgs - should be !var init_val compar_op compar_val incr_op (5 arguments)

isIncrementOperator

public static boolean isIncrementOperator(String txt)

copy

public ForContext copy(Context newParent)

Description copied from class: Context

deep copy of the context, its status, and its children

Specified by:

copy in class Context

Parameters:

newParent - parent to attach the copied context too
