Constructor Detail

ShiftLeft

public ShiftLeft(java.lang.Class<T> c)

Builds ShiftLeft 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,
            java.lang.Integer y)

Given integral arguments x and y, returns x << y

Specified by:

fn in class BinaryFunctor<T extends java.lang.Number,java.lang.Integer,T extends java.lang.Number>

Returns:

x << y

accept

public void accept(Visitor v)

Calls the Visitor's visit(ShiftLeft) 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
