A factory method, implemented via a macro, that produces a
PosZLong
if passed a valid Long
literal, otherwise a compile time error.
A factory method, implemented via a macro, that produces a
PosZLong
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 non-negative Long
literal,
i.e., with a value greater than or equal to 0, it will return
a PosZLong
representing that value. Otherwise,
the passed Long
expression is either a literal
that is 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.
the Long
literal expression to inspect at
compile time, and if non-negative, to return wrapped in a
PosZLong

the specified, valid Long
literal value wrapped
in a PosZLong
. (If the specified expression is not a valid
Long
literal, the invocation of this method will not
compile.)
A factory/assertion method that produces an PosZLong
given a
valid Long
value, or throws AssertionError
,
if given an invalid Long
value.
A factory/assertion method that produces an PosZLong
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 non-negative Long
,
i.e., a value greater than or equal to 0, it will
return a PosZLong
representing that value,
Otherwise, the passed Long
value is 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 this method 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 or zero.

A factory method that produces an Option[PosZLong]

Long
value.
A factory method that produces an Option[PosZLong]
given a
Long
value.
This method will inspect the passed Long
value
and if it is a non-negative Long
,
i.e., a value greater than or equal to 0, it will
return a PosZLong
representing that value,
wrapped in a Some
. Otherwise, the passed
Long
value is negative, so this method
will return None
.

A factory method that produces a PosZLong
given a
Long

.
This method will inspect the passed Long
value and if
it is a positive or zero Long
, i.e., a value greater
than or equal to 0L, it will return a PosZLong
representing that value.
Otherwise, the passed Long
value is negative, so this
method will return the passed default
value.
