it should still fix some issue I have an entity called Band with a attribute List genres, Genres is a ENUM with the following values: ALTERNATIVE_ROCK("Alternative Rock"), CLASSIC_ROCK("Classic Rock"), HARD_ROCK("Hard Rock"), HEAVY_METAL("Heavy Metal"),PROGRESSIVE_ROCK("Progressive Rock"); , This works for Hibernate 4
code :
    Query q = s
            .createQuery("SELECT b FROM Q27715453$Band b JOIN b.genres g WHERE g IN (:genres)");
    q.setParameterList("genres", Arrays.asList(Genres.ROCK, Genres.CLASSIC));
    System.out.println(Arrays.toString(q.list().toArray()));

This might help you Why implement your own, when you can use Java's own implementation for this?
code :
 YourEnum yourEnum = Enum.valueOf(YourEnum.class, value);
private static <E extends Enum<E>> E getEnum(Class<E> enumClass, String name){
    try {
        return Enum.valueOf(enumClass, name);
    } catch(IllegalArgumentException e) {
        return null;
    }
}
getEnum(Enum1.class, "A")

I wish this help you This is possible in OpenAPI 3.0. All parameters now use a schema, and, by extension, can $ref the schemas.
code :

      parameters:
        - in: query
          name: action
          schema:

Swift enum function with string parameter calling with a parameter of the enum class

like below fixes the issue I have played around with many variants of doing this over the last couple of years and have settled on the below. It is similar to @rmaddy's version but the rawValue of the enum is a String so that it is easy to convert back and forth between the name and the enum.
I then have static var's for the actual colours themselves. This allows me to refer to the colours in a similar way to UIColor
code :
view.backgroundColor = Palette.blueColor
view.backgroundColor = Palette.colorNamed("blue")
enum Palette : String
{
    case white
    case orange
    case red
    case pink
    case purple
    case blue

    static func color( named:String) -> UIColor?
    {
        switch named
        {
           case white.rawValue : return whiteColor
           case orange.rawValue : return orangeColor
           case red.rawValue : return redColor
           case pink.rawValue : return pinkColor
           case purple.rawValue : return purpleColor
           case blue.rawValue : return blueColor
           default : return nil
        }
    }

    static let whiteColor = color( withHex:0xffffff)
    static let orangeColor = color( withHex:0xfc622f)
    static let redColor = color( withHex:0xdd202b)
    static let pinkColor = color( withHex:0xff2f7e)
    static let purpleColor = color( withHex:0x9166e6)
    static let blueColor = color( withHex:0x049edd)
}

extension UIColor
{
    convenience init( withHexAlpha hex:UInt32)
    {
        let red   = CGFloat((hex >> 24) & 0xff) / 255.0
        let green = CGFloat((hex >> 16) & 0xff) / 255.0
        let blue  = CGFloat((hex >>  8) & 0xff) / 255.0
        let alpha = CGFloat((hex >>  0) & 0xff) / 255.0

        self.init( red:red, green:green, blue:blue, alpha:alpha)
    }

    convenience init( withHex hex:UInt32)
    {
       self.init( withHexAlpha:(hex << 8) | 0xff)
    }
}
Moshi Custom Adapter for generic List<T:Enum> returns List<List<T:Enum>> instead of List<T:Enum>

Moshi Custom Adapter for generic List<T:Enum> returns List<List<T:Enum>> instead of List<T:Enum>

Hope that helps (Also opened an issue here: https://github.com/square/moshi/issues/768 but was asked to open also a stackoverflow question) I am writing a generic adapter to convert a json-string with lists of enum values. The standard-adapter for enums throws an exception when the list contains an enum-value that is not available. I want to create an adapter that simply skips unknown enum values instead of throwing an exception. I succeeded partially, but for some reason, the object that was converted was not a List but instead a List>. , Register your adapter as handling List, not Tags.
code :
.add(Types.newParameterizedType(List::class.java, Tags::class.java),
    SkipNotFoundEnumInEnumListAdapter(Tags::class))
override fun fromJson(jsonReader: JsonReader): List<T> {
  val list = ArrayList<T>()
  jsonReader.beginArray()
  while(jsonReader.hasNext()){
    val jsonNameValue = jsonReader.nextString()
    val entry = jsonNameToEnum[jsonNameValue]
    if(entry!= null){
      list.add(entry)
    }
  }
  jsonReader.endArray()
  return list
}
class SkipNotFoundEnumInEnumListAdapter<T : Enum<T>>(enumType: Class<T>) : JsonAdapter<List<T>>() {
  private val nameStrings: Array<String>
  private val constants: Array<T>
  private val options: JsonReader.Options

  init {
    try {
      constants = enumType.enumConstants
      nameStrings = Array(constants.size) {
        val constant = constants[it]
        val annotation = enumType.getField(constant.name).getAnnotation(Json::class.java)
        annotation?.name ?: constant.name
      }
      options = JsonReader.Options.of(*nameStrings)
    } catch (e: NoSuchFieldException) {
      throw AssertionError("Missing field in " + enumType.name, e)
    }

  }

  @Throws(IOException::class)
  override fun fromJson(reader: JsonReader): List<T> {
    reader.beginArray()
    val list = mutableListOf<T>()
    while (reader.hasNext()) {
      val index = reader.selectString(options)
      if (index != -1) {
        list += constants[index]
      } else {
        reader.skipValue()
      }
    }
    reader.endArray()
    return list
  }

  @Throws(IOException::class)
  override fun toJson(writer: JsonWriter, value: List<T>?) {
    if (value == null) {
      throw IllegalArgumentException("Wrap in .nullSafe()")
    }
    writer.beginArray()
    for (i in value.indices) {
      writer.value(nameStrings[value[i].ordinal])
    }
    writer.endArray()
  }
}

fixed the issue. Will look into that further ...ok - figured it out. In case anyone else is confused, here is what I discovered. It seems that by default, the table is created using the ordinal value (in my case CurrencyType.ordinal()) so the column ends up looking like CURRENCY INTEGER NOT NULL when the table is created.
This is less than ideal as if I change the Enum type (i.e. the order of the values), this will break everything. The good news is I can force it to save the String value (CurrencyType.name()) by adding a @Enumerated(EnumType.STRING) to the method, so it will look like:
