A factory method, implemented via a macro, that produces a
PosFloat
if passed a validFloat
literal, otherwise a compile time error.A factory method, implemented via a macro, that produces a
PosFloat
if passed a validFloat
literal, otherwise a compile time error.The macro that implements this method will inspect the specified
Float
expression at compile time. If the expression is a positiveFloat
literal, it will return aPosFloat
representing that value. Otherwise, the passedFloat
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 inspectsFloat
literals at compile time, whereasfrom
inspectsFloat
values at run time.- value
the
Float
literal expression to inspect at compile time, and if positive, to return wrapped in aPosFloat
at run time.- returns
the specified, valid
Float
literal value wrapped in aPosFloat
. (If the specified expression is not a validFloat
literal, the invocation of this method will not compile.)

A factory/assertion method that produces a

given a validFloat
value, or throwsAssertionError
, if given an invalidFloat
value.A factory/assertion method that produces a
PosFloat
given a validFloat
value, or throwsAssertionError
, if given an invalidFloat
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
, orrightOrElse
.This method will inspect the passed
Float
value and if it is a positiveFloat
, it will return aPosFloat
representing that value. Otherwise, the passedFloat
value is not positive, so this method will throwAssertionError
.This factory method differs from the
apply
factory method in thatapply
is implemented via a macro that inspectsFloat
literals at compile time, whereasfrom
inspectsFloat

orensuring
call in that you get something you didn't already have if the assertion succeeds: a type that promises aFloat
is positive.- value
the
Float
to inspect, and if positive, return wrapped in aPosFloat
.- returns
the specified
Float
value wrapped in aPosFloat
