Is it possible to pass variables to a enum?
1
I have a class that validates strings using a "ValidationRequirements" data class and returns an Enum error message if its invalid.
Depending on what kind of requirements are passed the enum should adjust the string to match it.
ValidationRequirements:
data class ValidationRequirements(
//--------CONFIG_REQUIREMENTS--------
val PREFIX_STRING: String,
val REQUIRED_LENGTH: Int,
val MAXIMUM_LENGTH: Int,
val REQUIRE_SPECIAL_CHARACTERS: Boolean,
val REQUIRE_DIGITS: Boolean,
val REQUIRE_LOWER_CASE: Boolean,
val REQUIRE_UPPER_CASE: Boolean,
val REQUIRE_SPACE_SEPARATION: Boolean
)
Enum:
enum class StringStrengthReport(private val errorMessage: String) {
INVALID_EMAIL_FORMAT("Invalid email formatn"),
TO_SHORT(" requires at least 6 charactersn"),
LOWER_CASE_REQUIRED(" requires at least one lower case charactern"),
UPPER_CASE_REQUIRED(" requires at least one upper case charactern"),
DIGIT_REQUIRED(" requires at least one numeric charactern"),
SPECIAL_CHARACTER_REQUIRED(" requires at least one special character (i.e !&?#%)n"),
MAX_LENGTH_EXCEEDED(" max length is 32 charactersn"),
NULL_STRING(TO_SHORT.errorMessage),
VALID(" is valid!n");
}
Is it possible to pass the requirements to change min/max length for different kind of strings?

Use sealed class instead:
sealed class StringStrengthReport(private val message: String) {
override fun toString() = message
}
class InvalidEmailFormat(): StringStrengthReport("Invalid email format")
class TooShort(val minLength: Int): StringStrengthReport("Requires at least $minLength characters")
Results in:
println(InvalidEmailFormat()) // Invalid email format
println(TooShort(7)) // Requires at least 7 characters
