public boolean accepts(java.lang.Class<?> extensionType,
                       java.lang.reflect.Method method)

Description copied from interface: ExtensionHandlerFactory

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

Specified by:

accepts in interface ExtensionHandlerFactory

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

public java.util.Optional<ExtensionHandler> createExtensionHandler(java.lang.Class<?> extensionType,
                                                                   java.lang.reflect.Method method)

Description copied from interface: ExtensionHandlerFactory

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

Specified by:

createExtensionHandler in interface ExtensionHandlerFactory

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()
