public abstract class IntOperation
extends PrimitiveFunction

An abstract base class for integer arithmetic functions such as +. These functions are all "curried", which means that they expect one argument (the left operand) and then produce a new function which in turn expects one argument (the right operand) before producing the final result of the arithmetic. This is necessary because we are requiring all functions to take just one argument.

compute

public abstract int compute(int i1,
                            int i2)

This method should be implemented in each concrete subclass. This is where the actual operation takes place, whether that be +, -, or whatnot.

Parameters:

i1 - the left operand

i2 - the right operand

Returns:

the result of the computation on i1 and i2

apply

public Value apply(Value arg1)

Description copied from interface: Function

Apply this function to a specified argument Value.

Parameters:

arg1 - the argument Value

Returns:

the result Value from the function application.
