Annotation Interface MaxMindDbCreator

@Retention(RUNTIME)
@Target({METHOD,CONSTRUCTOR})
public @interface MaxMindDbCreator

MaxMindDbCreator is an annotation that can be used to mark a static factory method or constructor that should be used to create an instance of a class from a decoded value when decoding a MaxMind DB file.

This is similar to Jackson's @JsonCreator annotation and is useful for types that need custom deserialization logic, such as enums with non-standard string representations.

Example usage:

public enum ConnectionType {
    DIALUP("Dialup"),
    CABLE_DSL("Cable/DSL");

    private final String name;

    ConnectionType(String name) {
        this.name = name;
    }

    @MaxMindDbCreator
    public static ConnectionType fromString(String s) {
        return switch (s) {
            case "Dialup" -> DIALUP;
            case "Cable/DSL" -> CABLE_DSL;
            default -> null;
        };
    }
}
