Normalization

Defines a custom way to normalize instances of a type.

For example, to normalize Doubles by truncating off any decimal part, you might write:

import org.scalactic._

val truncated =
  new Normalization[Double] {
   def normalized(d: Double) = d.floor
 }

Given this definition you could use it with the Explicitly DSL like this:

import org.scalatest._
import Matchers._
import TypeCheckedTripleEquals._

(2.1 should === (2.0)) (after being truncated)

Note that to use a Normalization with the Explicitly DSL, you'll need to be using either TypeCheckedTripleEquals or ConversionCheckedTripleEquals. If you're just using plain-old TripleEquals, you'll need a Uniformity, a Normalization subclass.

If you make the truncated val implicit and import or mix in the members of NormMethods, you can access the behavior by invoking .norm on Doubles.

implicit val doubleNormalization = truncated
import NormMethods._

val d = 2.1
d.norm // returns 2.0

abstract def normalized(a: A): A

Returns a normalized form of the passed object.
Returns a normalized form of the passed object.
If the passed object is already in normal form, this method may return the same instance passed.
a
the object to normalize
returns
the normalized form of the passed object

final def and(other: Normalization[A]): Normalization[A]

Returns a new Normalization that composes this and the passed Normalization.
Returns a new Normalization that composes this and the passed Normalization.
The normalized method of the Normalization returned by this method returns a normalized form of the passed object obtained by forwarding the passed value first to this Normalization's normalized method, then passing that result to the other Normalization's normalized method. Essentially, the body of the composed normalized method is:
```
normalizationPassedToAnd.normalized(normalizationOnWhichAndWasInvoked.normalized(a))
```
other
a Normalization to 'and' with this one
returns
a Normalization representing the composition of this and the passed Normalization
