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.
the object to normalize
the normalized form of the passed object
Returns a new Uniformity that combines this and the passed Uniformity.
Returns a new Uniformity that combines this and the passed Uniformity.
The normalized and normalizedOrSame methods
of the Uniformity returned by this method return a result
obtained by forwarding the passed value first to this Uniformity's implementation of the method,
then passing that result to the other Uniformity's implementation of the method, respectively.
Essentially, the body of the composed normalized method is:
uniformityPassedToAnd.normalized(uniformityOnWhichAndWasInvoked.normalized(a))
And the body of the composed normalizedOrSame method is:
uniformityPassedToAnd.normalizedOrSame(uniformityOnWhichAndWasInvoked.normalizedOrSame(a))
The normalizeCanHandle method of the Uniformity returned by this method returns a result
obtained by anding the result of forwarding the passed value to this Uniformity's implementation of the method
with the result of forwarding it to the passed Uniformity's implementation.
Essentially, the body of the composed normalizeCanHandle method is:
uniformityOnWhichAndWasInvoked.normalizeCanHandle(a) && uniformityPassedToAnd.normalizeCanHandle(a)
a Uniformity to 'and' with this one
a Uniformity representing the composition of this and the passed Uniformity
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))
a Normalization to 'and' with this one
a Normalization representing the composition of this and the passed Normalization
Returns true if the passed Any is a String.
Returns true if the passed Any is a String.
true if the passed Any is a String.
Normalizes the passed object if it is a String.
Normalizes the passed object if it is a String.
This method returns either:
String, the result of passing that string to normalizedthe object to normalize, if appropriate
a normalized form of any passed String, or the same object if not a String.
Converts this Uniformity to a NormalizingEquality[A] whose normalized,
normalizedCanHandle, and normalizedOrSame methods delegate
to this Uniformity[A] and whose afterNormalizationEquality field returns the
implicitly passed Equality[A].
Converts this Uniformity to a NormalizingEquality[A] whose normalized,
normalizedCanHandle, and normalizedOrSame methods delegate
to this Uniformity[A] and whose afterNormalizationEquality field returns the
implicitly passed Equality[A].
the Equality that the returned NormalizingEquality
will delegate to determine equality after normalizing both left and right (if appropriate) sides.
Converts this Normalization to a NormalizingEquivalence[A] whose normalized
method delegates to this Normalization[A] and whose afterNormalizationEquivalence field returns the
implicitly passed Equivalence[A].
Converts this Normalization to a NormalizingEquivalence[A] whose normalized
method delegates to this Normalization[A] and whose afterNormalizationEquivalence field returns the
implicitly passed Equivalence[A].
the Equivalence that the returned NormalizingEquivalence
will delegate to determine equality after normalizing both left and right (if appropriate) sides.
Convenience base trait for string
Uniformitys.This trait defines a
normalizedCanHandlemethod that returns true if the passedAnyis aStringand anormalizedOrSamemethod that normalizes any passedStrings via thenormalizedmethod, which is left abstract for subclasses to fill in.Here's an example in which
AbstractStringUniformityis used to normalize strings by ensuring the first character, if any, is capitalized:Here's an example of using the
