Concrete methods
A factory/assertion method that produces a NegZFloat
given a
valid Float
value, or throws AssertionError
,
if given an invalid Float
value.
A factory/assertion method that produces a NegZFloat
given a
valid Float
value, or throws AssertionError
,
if given an invalid Float
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 Float
value and if
it is a non-positive Float
, it will return a NegZFloat
representing that value.
Otherwise, the passed Float
value is not non-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 Float
literals at
compile time, whereas from
inspects
Float
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 Float
is positive.
- Value parameters:
- value
the
Float
to inspect, and if non-positive, return wrapped in aNegZFloat
.
- Returns:
the specified
Float
value wrapped in aNegZFloat
, if it is non-positive, else throwsAssertionError
.- Throws:
- AssertionError
if the passed value is not non-positive

A factory method, implemented via a macro, that produces a
NegZFloat
if passed a valid Float
literal, otherwise a compile time error.
A factory method, implemented via a macro, that produces a
NegZFloat
if passed a valid Float
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 non-positive Float
literal,
it will return a NegZFloat
representing that value.
Otherwise, the passed Float
expression is either a literal
that is not non-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 Float
literals at compile
time, whereas from
inspects Float

- Value parameters:
- value
the
Float
literal expression to inspect at compile time, and if non-positive, to return wrapped in aNegZFloat
at run time.
- Returns:
the specified, valid
Float
literal value wrapped in aNegZFloat

literal, the invocation of this method will not compile.)- Source:
