Method Detail

findBestConstructor	back to summary
private static <T> Constructor<?> findBestConstructor(Class<T> spiInterface, Class<? extends T> implementationClass) Find the "best" constructor for the supplied implementation class. For backward compatibility, it first checks for a single constructor and returns that. If there are multiple constructors, it checks for a default constructor which takes precedence over any other constructors. Otherwise, this method throws an exception stating that it failed to find a suitable constructor.
