def ensuringValid(value: Double): NegFiniteDouble

A factory/assertion method that produces a NegFiniteDouble given a valid Double value, or throws AssertionError, if given an invalid Double value.

A factory/assertion method that produces a NegFiniteDouble given a valid Double value, or throws AssertionError, if given an invalid Double value.

This method will inspect the passed Double value and if it is a finite negative Double, it will return a NegFiniteDouble representing that value. Otherwise, the passed Double value is not finite negative, so this method will throw AssertionError.

This factory method differs from the apply factory method in that apply is implemented via a macro that inspects Double literals at compile time, whereas from inspects Double values at run time. It differs from a vanilla assert or ensuring call in that you get something you didn't already have if the assertion succeeds: a type that promises a Double is finite negative.

Value parameters

value

the Double to inspect, and if finite negative, return wrapped in a NegFiniteDouble.

Attributes

Returns

the specified Double value wrapped in a NegFiniteDouble, if it is finite negative, else throws AssertionError.

Throws
AssertionError

if the passed value is not finite negative

def from(value: Double): Option[NegFiniteDouble]

A factory method that produces an Option[NegFiniteDouble] given a Double value.

A factory method that produces an Option[NegFiniteDouble] given a Double value.

This method will inspect the passed Double value and if it is a finite negative Double, it will return a NegFiniteDouble representing that value, wrapped in a Some. Otherwise, the passed Double value is not finite negative, so this method will return None.

This factory method differs from the apply factory method in that apply is implemented via a macro that inspects Double literals at compile time, whereas from inspects Double values at run time.

Value parameters

A factory method that produces a NegFiniteDouble given a Double value and a default NegFiniteDouble.

This method will inspect the passed Double value and if it is a finite negative Double, it will return a NegFiniteDouble representing that value. Otherwise, the passed Double value is finite negative, so this method will return the passed default value.

def goodOrElse[B](value: Double)(f: Double => B): Or[NegFiniteDouble, B]

A factory/validation method that produces a NegFiniteDouble, wrapped in a Good, given a valid Double value, or if the given Double is invalid, an error value of type B produced by passing the given invalid Double value to the given function f, wrapped in a Bad.

A factory/validation method that produces a NegFiniteDouble, wrapped in a Good, given a valid Double value, or if the given Double is invalid, an error value of type B produced by passing the given invalid Double value to the given function f, wrapped in a Bad.

This method will inspect the passed Double value and if it is a finite negative Double, it will return a NegFiniteDouble representing that value, wrapped in a Good. Otherwise, the passed Double value is not finite negative, so this method will return a result of type B obtained by passing the invalid Double value to the given function f, wrapped in a Bad.

This factory method differs from the apply factory method in that apply is implemented via a macro that inspects Double literals at compile time, whereas this method inspects Double values at run time.

Value parameters

def passOrElse[E](value: Double)(f: Double => E): Validation[E]

A validation method that produces a Pass given a valid Double value, or an error value of type E produced by passing the given invalid Int value to the given function f, wrapped in a Fail.

This method will inspect the passed Double value and if it is a finite negative Double, it will return a Pass. Otherwise, the passed Double value is finite negative, so this method will return a result of type E obtained by passing the invalid Double value to the given function f, wrapped in a Fail.

This factory method differs from the apply factory method in that apply is implemented via a macro that inspects Double literals at compile time, whereas this method inspects Double values at run time.

A factory/validation method that produces a NegFiniteDouble, wrapped in a Right, given a valid Double value, or if the given Double is invalid, an error value of type L produced by passing the given invalid Double value to the given function f, wrapped in a Left.

This method will inspect the passed Double value and if it is a finite negative Double, it will return a NegFiniteDouble representing that value, wrapped in a Right. Otherwise, the passed Double value is not finite negative, so this method will return a result of type L obtained by passing the invalid Double value to the given function f, wrapped in a Left.

def tryingValid(value: Double): Try[NegFiniteDouble]

A factory/validation method that produces a NegFiniteDouble, wrapped in a Success, given a valid Float value, or if the given Float is invalid, an AssertionError, wrapped in a Failure.

A factory/validation method that produces a NegFiniteDouble, wrapped in a Success, given a valid Float value, or if the given Float is invalid, an AssertionError, wrapped in a Failure.

Note: you should use this method only when you are convinced that it will always succeed, i.e., never throw an exception. It is good practice to add a comment near the invocation of this method indicating ''why'' you think it will always succeed to document your reasoning. If you are not sure an ensuringValid call will always succeed, you should use one of the other factory or validation methods provided on this object instead: isValid, tryingValid, passOrElse, goodOrElse, or rightOrElse.

This method will inspect the passed Float value and if it is a finite negative Float, it will return a NegFiniteDouble representing that value, wrapped in a Success. Otherwise, the passed Float value is not finite negative, so this method will return an AssertionError, wrapped in a Failure.

This factory method differs from the apply factory method in that apply is implemented via a macro that inspects Float literals at compile time, whereas this method inspects Float values at run time.

Value parameters

value

the Float to inspect, and if finite negative, return wrapped in a Success(NegFiniteDouble).

Attributes

Returns

the specified Float value wrapped in a Success(NegFiniteDouble), if it is finite negative, else a Failure(AssertionError).

implicit inline def apply(value: => Double): NegFiniteDouble

A factory method, implemented via a macro, that produces a NegFiniteDouble if passed a valid Double literal, otherwise a compile time error.

A factory method, implemented via a macro, that produces a NegFiniteDouble if passed a valid Double literal, otherwise a compile time error.

The macro that implements this method will inspect the specified Double expression at compile time. If the expression is a finite negative Double literal, it will return a NegFiniteDouble representing that value. Otherwise, the passed Double expression is either a literal that is not finite negative, or is not a literal, so this method will give a compiler error.

This factory method differs from the from factory method in that this method is implemented via a macro that inspects Double literals at compile time, whereas from inspects Double values at run time.

Value parameters

value

the Double literal expression to inspect at compile time, and if finite negative, to return wrapped in a NegFiniteDouble at run time.

Attributes

Returns

the specified, valid Double literal value wrapped in a NegFiniteDouble. (If the specified expression is not a valid Double literal, the invocation of this method will not compile.)
