Specified by:

getLength in class Argument

Returns:

an int

Description copied from class: Argument

Writes itself to stack.

Specified by:

writeToStack in class Argument

Parameters:

stack - it's byte array, where Argument will be written

offset - offset in stack

Description copied from class: Argument
