A factory method, implemented via a macro, that produces a
NegDouble if passed a valid Double
literal, otherwise a compile time error.
A factory method, implemented via a macro, that produces a
NegDouble 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 negative Double literal,
it will return a NegDouble representing that value.
Otherwise, the passed Double expression is either a literal
that is not 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 Double literals at compile
time, whereas from inspects Double
values at run time.
the Double literal expression to
inspect at compile time, and if negative, to return
wrapped in a NegDouble at run time.
the specified, valid Double literal
value wrapped in a NegDouble. (If the
specified expression is not a valid Double
literal, the invocation of this method will not
compile.)
A factory/assertion method that produces a NegDouble given a
valid Double value, or throws AssertionError,
if given an invalid Double value.
A factory/assertion method that produces a NegDouble 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 negative Double, it will return a NegDouble
representing that value. Otherwise, the passed Double value is not 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 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 negative.
the Double to inspect, and if negative, return
wrapped in a NegDouble.
the specified Double value wrapped in a
NegDouble, if it is negative, else
throws AssertionError.
AssertionError if the passed value is not negative
A factory method that produces an Option[NegDouble] given a
Double value.
A factory method that produces an Option[NegDouble] given a
Double value.
This method will inspect the passed Double value and if
it is a negative Double, it will return a NegDouble
representing that value, wrapped in a Some. Otherwise, the passed Double
value is not negative, so this method will return None.
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.
the Double to inspect, and if negative, return
wrapped in a Some[NegDouble].
the specified Double value wrapped in a
Some[NegDouble], if it is NegDouble, else
None.
A factory method that produces a NegDouble given a
Double value and a default NegDouble.
A factory method that produces a NegDouble given a
Double value and a default NegDouble.
This method will inspect the passed Double value and if
it is a negative Double, it will return a NegDouble
representing that value. Otherwise, the passed Double value is negative,
so this method will return the passed default value.
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.
the Double to inspect, and if negative, return.
the NegDouble to return if the passed
Double value is not negative.
the specified Double value wrapped in a
NegDouble, if it is negative, else the
default NegDouble value.
A factory/validation method that produces a NegDouble, wrapped
in a Good, given a valid Double value, or if the
given Double is invalid, an error value of type B
produced by passing the given invalid Double value
to the given function f, wrapped in a Bad.
A factory/validation method that produces a NegDouble, wrapped
in a Good, given a valid Double value, or if the
given Double is invalid, an error value of type B
produced by passing the given invalid Double value
to the given function f, wrapped in a Bad.
This method will inspect the passed Double value and if
it is a negative Double, it will return a NegDouble
representing that value, wrapped in a Good.
Otherwise, the passed Double value is not negative, so this
method will return a result of type B obtained by passing
the invalid Double value to the given function f,
wrapped in a Bad.
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 this method inspects
Double values at run time.
the Double to inspect, and if negative, return
wrapped in a Good(NegDouble).
the specified Double value wrapped
in a Good(NegDouble), if it is negative, else a Bad(f(value)).
A predicate method that returns true if a given
Double value is negative.
A predicate method that returns true if a given
Double value is negative.
the Double to inspect, and if negative, return true.
true if the specified Double is positive, else false.

A validation method that produces a Pass
given a valid Double value, or
an error value of type E produced by passing the
given invalid Int value
to the given function f, wrapped in a Fail.
A validation method that produces a Pass
given a valid Double value, or
an error value of type E produced by passing the
given invalid Int value
to the given function f, wrapped in a Fail.
This method will inspect the passed Double value and if
it is a negative Double, it will return a Pass.
Otherwise, the passed Double value is negative, so this
method will return a result of type E obtained by passing
the invalid Double value to the given function f,
wrapped in a Fail.
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 this method inspects

the Int to validate that it is negative.
a Pass if the specified Int value is negative,
else a Fail containing an error value produced by passing the
specified Double to the given function f.
A factory/validation method that produces a NegDouble, wrapped
in a Right, given a valid Double value, or if the
given Double is invalid, an error value of type L
produced by passing the given invalid Double value
to the given function f, wrapped in a Left.
A factory/validation method that produces a NegDouble, wrapped
in a Right, given a valid Double value, or if the
given Double is invalid, an error value of type L
produced by passing the given invalid Double value
to the given function f, wrapped in a Left.
This method will inspect the passed Double value and if
it is a negative Double, it will return a NegDouble
representing that value, wrapped in a Right.
Otherwise, the passed Double value is not negative, so this
method will return a result of type L obtained by passing
the invalid Double value to the given function f,
wrapped in a Left.
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 this method inspects

the Double to inspect, and if negative, return
wrapped in a Right(NegDouble).

A factory/validation method that produces a NegDouble, wrapped
in a Success, given a valid Float value, or if the
given Float is invalid, an AssertionError, wrapped
in a Failure.
A factory/validation method that produces a NegDouble, 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 negative Float, it will return a NegDouble
representing that value, wrapped in a Success.
Otherwise, the passed Float value is not negative, so this
method will return an AssertionError, wrapped in a Failure.
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 this method inspects

the Float to inspect, and if negative, return
wrapped in a Success(NegDouble).
