Constructor Detail

Plus

public Plus(java.lang.Class<T> c)
Builds Plus 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:
java.lang.IllegalArgumentException - if the given class has no Arithmetic implementation registered with the ArithmeticFactory
Method Detail

getType

public java.lang.Class<T> getType()
Returns the type of operands this instance supports


fn

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

Specified by:
fn in class BinaryFunctor<T extends java.lang.Number,T extends java.lang.Number,T extends java.lang.Number>
Returns:
the sum of two numeric arguments

accept

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

Specified by:
accept in interface Visitable
Overrides:
accept in class Functor<T extends java.lang.Number>

toString

public java.lang.String toString()
Overrides:
toString in class java.lang.Object
