Constructor Detail

Multiplies

public Multiplies(Class c)
Builds Multiplies functor for the given class. The class argument must be the same as the generic class argument (when generics are in use) or else a ClassCastException will be thrown when the functor is used.

Throws: IllegalArgumentException if the given class has no Arithmetic implementation registered with the ArithmeticFactory

Method Detail

accept

public void accept(Visitor v)
Calls the Visitor's visit(Multiplies) method, if it implements the nested Visitor interface.

fn

public T fn(T x, T y)
Given numeric arguments x and y, returns x * y

Returns: the product of two numeric arguments

toString

public String toString()
