public abstract class IntComparison
extends PrimitiveFunction

An abstract base class for integer comparison 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 true/false result. This is necessary because we are requiring all functions to take just one argument.

Method Detail

compute

public abstract boolean compute(int i1,
                                int i2)

This method should be implemented in each concrete subclass. This is where the actual comparison takes place, whether that be <, >, or whatnot.

Parameters:

i1 - the left operand

i2 - the right operand

Returns:

the result of comparing i1 with 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.
