Concrete methods

def ensuringValid(value: Long): NegLong

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

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

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 Long value and if it is a negative Long, it will return a NegLong representing that value. Otherwise, the passed Long value is not 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 Long literals at compile time, whereas from inspects Long 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 Long is positive.

Value parameters:
value

the Long to inspect, and if negative, return wrapped in a NegLong.

Returns:

the specified Long value wrapped in a NegLong, if it is negative, else throws AssertionError.

Throws:
AssertionError

if the passed value is not negative

def from(value: Long): Option[NegLong]

A factory method that produces an Option[NegLong] given a Long value.

A factory method that produces an Option[NegLong] given a Long value.

This method will inspect the passed Long value and if it is a negative Long, it will return a NegLong representing that value, wrapped in a Some. Otherwise, the passed Long value is not 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 Long literals at compile time, whereas from inspects Long values at run time.

Value parameters:
value

the Long to inspect, and if negative, return wrapped in a Some[NegLong].

Returns:

the specified Long value wrapped in a Some[NegLong], if it is negative, else None.

def fromOrElse(value: Long, default: => NegLong): NegLong

A factory method that produces a NegLong given a Long value and a default NegLong.

A factory method that produces a NegLong given a Long value and a default NegLong.

This method will inspect the passed Long value and if it is a negative Long, it will return a NegLong representing that value. Otherwise, the passed Long value is not 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 Long literals at compile time, whereas from inspects Long values at run time.

Value parameters:
default

the NegLong to return if the passed Long value is not negative.

value

the Long to inspect, and if negative, return.

Returns:

the specified Long value wrapped in a NegLong, if it is negative, else the default NegLong value.

def goodOrElse[B](value: Long)(f: Long => B): Or[NegLong, B]

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

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

This method will inspect the passed Long value and if it is a negative Long, it will return a NegLong representing that value, wrapped in a Good. Otherwise, the passed Long value is not negative, so this method will return a result of type B obtained by passing the invalid Long 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 Long literals at compile time, whereas this method inspects Long values at run time.

Value parameters:
value

the Long to inspect, and if negative, return wrapped in a Good(NegLong).

Returns:

the specified Long value wrapped in a Good(NegLong), if it is negative, else a Bad(f(value)).

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

A validation method that produces a Pass given a valid Long 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.

A validation method that produces a Pass given a valid Long 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 Long value and if it is a negative Long, it will return a Pass. Otherwise, the passed Long value is negative, so this method will return a result of type E obtained by passing the invalid Long 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 Long literals at compile time, whereas this method inspects Long values at run time.

Value parameters:
value

the Long to validate that it is negative.

Returns:

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

def rightOrElse[L](value: Long)(f: Long => L): Either[L, NegLong]

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

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

This method will inspect the passed Int value and if it is a negative Int, it will return a NegLong representing that value, wrapped in a Right. Otherwise, the passed Int value is not negative, so this method will return a result of type L obtained by passing the invalid Int 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 Int literals at compile time, whereas this method inspects Int values at run time.

Value parameters:
value

the Int to inspect, and if negative, return wrapped in a Right(NegLong).

Returns:

the specified Int value wrapped in a Right(NegLong), if it is negative, else a Left(f(value)).

implicit inline def apply(value: => Long): NegLong

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

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

The macro that implements this method will inspect the specified Long expression at compile time. If the expression is a negative Long literal, it will return a NegLong representing that value. Otherwise, the passed Long expression is either a literal that is not 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 Long literals at compile time, whereas from inspects Long values at run time.

Value parameters:
value

the Long literal expression to inspect at compile time, and if negative, to return wrapped in a NegLong at run time.

Returns:

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