  • Method Details

    • createAttributeInstance

      public abstract AttributeImpl createAttributeInstance(Class<? extends Attribute> attClass) throws UndeclaredThrowableException
      Returns an AttributeImpl for the supplied Attribute interface class.
      UndeclaredThrowableException - A wrapper runtime exception thrown if the constructor of the attribute class throws a checked exception. Note that attributes should not throw or declare checked exceptions; this may be verified and fail early in the future.
    • getStaticImplementation

      public static <A extends AttributeImpl> AttributeFactory getStaticImplementation(AttributeFactory delegate, Class<A> clazz)
      Returns an AttributeFactory returning an instance of the given clazz for the attributes it implements. The given clazz must have a public no-arg constructor. For all other attributes it calls the given delegate factory as fallback. This method can be used to prefer a specific AttributeImpl which combines multiple attributes over separate classes.

      Please save instances created by this method in a static final field, because on each call, this does reflection for creating a MethodHandle.
