Concrete methods
A factory/assertion method that produces an PosLong
given a valid Long
value, or throws AssertionError
, if given an invalid Long
value.
A factory/assertion method that produces an PosLong
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 positive Long
, it will return a PosLong
representing that value. Otherwise, the passed Long
value is not positive, 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.

A factory method that produces a PosLong
given a Long
value and a default PosLong

A factory/validation method that produces a PosLong

A factory method, implemented via a macro, that produces a PosLong
if passed a valid Long
literal, otherwise a compile time error.
A factory method, implemented via a macro, that produces a PosLong
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 positive Long
literal, it will return a PosLong
representing that value. Otherwise, the passed Long
expression is either a literal that is not positive, 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.
