The generated code on the other hand returns `null` by default. \n\n**Example:**\nBase interface:\n\n``` java\n@SharedPref(SharedPref.Scope.UNIQUE)\npublic interface PrefsClass {\n    /* Documentation of @DefaultStringSet states:\n     * \"Use on methods in SharedPref annotated class.\n     * The generated method will return an empty java.util.Set of Strings by default.\"\n     */\n    @DefaultStringSet\n    public Set\u003cString\u003e stringSetPref();\n}\n```\n\nGenerated code:\n\n``` java\npublic final class PrefsClass_ extends SharedPreferencesHelper{\n    // ...\n    public StringSetPrefField stringSetPref() {\n        // returns null instead of empty Set\n        return stringSetField(\"stringSetPref\", null);\n    }\n}\n```\n\nExpected code:\n\n``` java\npublic final class PrefsClass_ extends SharedPreferencesHelper{\n    // ...\n    public StringSetPrefField stringSetPref() {\n        // returns a new empty set (not necessarily HashSet)\n        return stringSetField(\"stringSetPref\", new HashSet\u003cString\u003e());\n    }\n}\n```\n","author":{"url":"https://github.com/ironjan","@type":"Person","name":"ironjan"},"datePublished":"2015-03-27T12:52:41.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":1},"url":"https://github.com/1357/androidannotations/issues/1357"}
