Concrete methods
A factory/assertion method that produces a PosDouble
given a valid Double
value, or throws AssertionError
, if given an invalid Double
value.
A factory/assertion method that produces a PosDouble
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 positive Double
, it will return a PosDouble
representing that value. Otherwise, the passed Double
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 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 positive.

A factory/validation method that produces a PosDouble
, 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 positive Float
, it will return a PosDouble
representing that value, wrapped in a Success
. Otherwise, the passed Float
value is not positive, so this method will return an AssertionError
, wrapped in a Failure
.

A factory method, implemented via a macro, that produces a PosDouble
if passed a valid Double
literal, otherwise a compile time error.
A factory method, implemented via a macro, that produces a PosDouble
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 positive Double
literal, it will return a PosDouble
representing that value. Otherwise, the passed Double
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 Double
literals at compile time, whereas from
inspects Double
values at run time.
