Failure
Returns Left containing the errors if this is a Failure or a Right containing the value if this is a Success.
Returns Left containing the errors if this is a Failure or a Right containing the value if this is a Success.
Returns None if this is a Failure or a Some containing the value if this is a Success.
Returns None if this is a Failure or a Some containing the value if this is a Success.
Like map, but for partial function.
Like map, but for partial function. If p us not defined for the value, it return a Failure
val p: PartialFunction[Int, String] = { case 5 => "High five!" } Success(5).collect("OOoops")(p) == Success("High five!") Success(7).collect("OOoops")(p) == Failure(Seq("OOoops")) Failure(Seq("error")).collect("OOoops")(p) == Failure(Seq("error"))
the error to return if the p is not defined
the partial function to apply if this is a Success
a Success if this was a Success and p was defined, a Failure otherwise
filter Successful Validation if it does not match the predicate p
filter Successful Validation if it does not match the predicate p
val isFive: Int => Boolean = _ == 5 Success(5).filter("Not five")(isFive) == Success(5) Success(7).filter("Not five")(isFive) == Failure(Seq("Not five")) Failure(Seq("error")).filter("Not five")(isFive) == Failure(Seq("error"))
the error to return if the predicate p is not verified
the predicate to apply if this is a Success
a Success if this was a Success and the predicate matched, a Failure otherwise
filter Successful Validation if it does not match the predicate p
filter Successful Validation if it does not match the predicate p
the predicate to apply if this is a Success
a Success if this was a Success and the predicate matched, a Failure otherwise
Applies invalid if this is a Failure or valid if this is a Success.
Applies invalid if this is a Failure or valid if this is a Success.
the function to apply if this is a Failure

Creates a non-strict filter of this Validation.
Creates a non-strict filter of this Validation.
Note: the difference between c filter p and c withFilter p is that
the former creates a new vlaidation, whereas the latter only
restricts the domain of subsequent map, flatMap, foreach,
and withFilter operations.
the predicate used to test value.
an object of class WithFilter, which supports
map, flatMap, foreach, and withFilter operations.
All these operations apply to the value of this Validation
which satisfy the predicate p.
