    • Method Detail

      • values

        public static JavaType[] values()
        Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows: 
        for (JavaType c : JavaType.values())
    System.out.println(c);
        Returns:
        an array containing the constants of this enum type, in the order they are declared

      • valueOf

        public static JavaType valueOf​(java.lang.String name)
        Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
        Parameters:
        name - the name of the enum constant to be returned.
        Returns:
        the enum constant with the specified name
        Throws:
        java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
        java.lang.NullPointerException - if the argument is null

      • getTypeStub

        public TypeDescription getTypeStub()
        Returns at least a stub representing this type where the stub does not define any methods or fields. If a type exists for the current runtime, a loaded type representation is returned.
        Returns:
        A type description for this Java type.

      • load

        public java.lang.Class<?> load()
                        throws java.lang.ClassNotFoundException
        Loads the class that is represented by this Java type.
        Returns:
        A loaded type of this Java type.
        Throws:
        java.lang.ClassNotFoundException - If the represented type cannot be loaded.
