      • getElementTypes

        public static java.lang.reflect.Type[] getElementTypes​(com.google.gson.reflect.TypeToken<?> typeToken,
                                                       java.lang.Class<?> targetType)
        Determine the actual type arguments of the given type token with regard to the given target type.

      • getExpectedTypes

        public static java.util.Collection<java.lang.reflect.Type> getExpectedTypes​(java.lang.reflect.Type type)
        Return all possible types that can be expected when an element of the given type is parsed. If the type satisfies isEither(Type), a list of the corresponding type arguments is returned, otherwise a list containg the type itself is returned. Type parameters are not resolved by this method (use getElementTypes(TypeToken, Class) to get resolved parameters).

      • isEither

        public static boolean isEither​(java.lang.reflect.Type type)
        Test whether the given type is Either.

      • isTwoTuple

        public static boolean isTwoTuple​(java.lang.reflect.Type type)
        Test whether the given type is a two-tuple (pair).
