Method Details

accepts

boolean accepts(Class<?> extensionType,
 Method method)

Determines whether the factory can create an ExtensionHandler for combination of extension type and method.

Parameters:

extensionType - The extension type class

method - A method

Returns:

True if the factory can create an extension handler for extension type and method, false otherwise

createExtensionHandler

Optional<ExtensionHandler> createExtensionHandler(Class<?> extensionType,
 Method method)

Returns an ExtensionHandler instance for a extension type and method combination.

Parameters:

extensionType - The extension type class

method - A method

Returns:

An ExtensionHandler instance wrapped into an Optional. The optional can be empty. This is necessary to retrofit old code that does not have an accept/build code pair but unconditionally tries to build a handler and returns empty if it can not. New code should always return Optional.of(extensionHandler} and never return Optional.empty()
