ValueEnumFromValue

open class ValueEnumFromValue<Value, T : Enum<T>, ValueEnum<Value>>(default: T, enumEntries: <Error class: unknown class><T>) : EnumFromValue<Value, T> (source)

EnumFromValue implementation for enums that implement the ValueEnum interface.

fromValueOrNull is implemented to use the result of the following operation:

enumEntries.find { it.value == value }

Note that fromValueOrNull can still be overridden if the default implementation isn't desirable.
