  8. implicit macro def apply(value: Double): PosZDouble

    Permalink

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

    A factory method, implemented via a macro, that produces a PosZDouble 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 non-negative Double literal, it will return a PosZDouble representing that value. Otherwise, the passed Double expression is either a literal that is not non-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

    the Double literal expression to inspect at compile time, and if non-negative, to return wrapped in a PosZDouble at run time.

    returns

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

  11. def ensuringValid(value: Double): PosZDouble

    Permalink

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

    A factory/assertion method that produces a PosZDouble 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 non-negative Double, it will return a PosZDouble representing that value. Otherwise, the passed Double value is not non-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 non-negative.

    value

    the Double to inspect, and if non-negative, return wrapped in a PosZDouble.

    returns

    the specified Double value wrapped in a PosZDouble, if it is non-negative, else throws AssertionError.

    Exceptions thrown

    AssertionError if the passed value is not non-negative

  15. def from(value: Double): Option[PosZDouble]

    Permalink

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

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

    This method will inspect the passed Double value and if it is a non-negative Double, it will return a PosZDouble representing that value, wrapped in a Some. Otherwise, the passed Double value is not non-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

    the Double to inspect, and if non-negative, return wrapped in a Some[PosZDouble].

    returns

    the specified Double value wrapped in a Some[PosZDouble], if it is PosZDouble, else None.

  16. def fromOrElse(value: Double, default: ⇒ PosZDouble): PosZDouble

    Permalink

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

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

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

    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

    the Double to inspect, and if non-negative, return.

    default

    the PosZDouble to return if the passed Double value is not non-negative.

    returns

    the specified Double value wrapped in a PosZDouble, if it is non-negative, else the default PosZDouble value.

    A factory/validation method that produces a PosZDouble, 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 non-negative Double, it will return a PosZDouble representing that value, wrapped in a Good. Otherwise, the passed Double value is not non-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

    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 non-negative Double, it will return a Pass. Otherwise, the passed Double value is non-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.

    value

    the Int to validate that it is non-negative.

    returns

    a Pass if the specified Int value is non-negative, else a Fail containing an error value produced by passing the specified Double to the given function f.

  27. def rightOrElse[L](value: Double)(f: (Double) ⇒ L): Either[L, PosZDouble]

    Permalink

    A factory/validation method that produces a PosZDouble, 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.

    A factory/validation method that produces a PosZDouble, 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 non-negative Double, it will return a PosZDouble representing that value, wrapped in a Right. Otherwise, the passed Double value is not non-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.

    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

    the Double to inspect, and if non-negative, return wrapped in a Right(PosZDouble).

    returns

    the specified Double value wrapped in a Right(PosZDouble), if it is non-negative, else a Left(f(value)).

  28. def sumOf(first: PosZDouble, second: PosZDouble, rest: PosZDouble*): PosZDouble

    Permalink

    Returns the PosZDouble sum of the passed PosZDouble values first and value second, and the PosZDouble values passed as varargs rest.

    Returns the PosZDouble sum of the passed PosZDouble values first and value second, and the PosZDouble values passed as varargs rest.

    This method will always succeed (not throw an exception) because adding a non-negative Double to another non-negative Double will always result in another non-negative Double value (though the result may be infinity).

    This overloaded form of the sumOf method can sum more than two values, but unlike its two-arg sibling, will entail boxing.

  29. def sumOf(x: PosZDouble, y: PosZDouble): PosZDouble

    Permalink

    Returns the PosZDouble sum of the passed PosZDouble values x and y.

    Returns the PosZDouble sum of the passed PosZDouble values x and y.

    This method will always succeed (not throw an exception) because adding a non-negative Double to another non-negative Double will always result in another PosZDouble Double value (though the result may be infinity).

    This overloaded form of the method is used when there are just two arguments so that boxing is avoided. The overloaded sumOf that takes a varargs of PosZDouble starting at the third parameter can sum more than two values, but will entail boxing and may therefore be less efficient.

  32. def tryingValid(value: Double): Try[PosZDouble]

    Permalink

    A factory/validation method that produces a PosZDouble, 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 PosZDouble, 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 non-negative Float, it will return a PosZDouble representing that value, wrapped in a Success. Otherwise, the passed Float value is not non-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

    the Float to inspect, and if non-negative, return wrapped in a Success(PosZDouble).

    returns

    the specified Float value wrapped in a Success(PosZDouble), if it is non-negative, else a Failure(AssertionError).
