Not without adding some code yourself.
I have done this many times when values from some JSON string from a server
map to Enum values but these JSON strings don't map onto the names of the
Enum values directly.
I usually added a public static method to my Enum class, a factory that
produces its values based upon a String value:
public enum Type {
....
....
public static Type get(String typeStr) {
for (Type value : Type.values()) {
if (value.getType().equals(typeStr)) {
return value;
}
}
return null;
}
}
And now, as an example, in any other part of the code, you can just call
Type.get("event/one") and get the correct Type value back.
