Class ServiceProviderForProcessor

java.lang.Object

ball.annotation.processing.JavaxLangModelUtilities

ball.annotation.processing.AbstractProcessor

ball.annotation.processing.AnnotatedProcessor

ball.annotation.processing.ServiceProviderForProcessor

All Implemented Interfaces:

ClassFileProcessor, JavaLangReflectMethods, Processor

@ServiceProviderFor(javax.annotation.processing.Processor.class)
@For(ServiceProviderFor.class)
public class ServiceProviderForProcessor
extends AnnotatedProcessor
implements ClassFileProcessor

Processor implementation to check Classes annotated with ServiceProviderFor to verify the annotated Class:

1. Is concrete
2. Has a public no-argument constructor
3. Implements the Classes specified by ServiceProviderFor.value()

or implements Java 9's java.util.ServiceLoader.Provider public static T provider() method.

Note: Google offers a similar AutoService library.

Method Detail

process

protected void process(RoundEnvironment roundEnv,
                       TypeElement annotation,
                       Element element)

Description copied from class: AnnotatedProcessor

Callback method to process an annotated Element. Default implementation does nothing.

Overrides:

process in class AnnotatedProcessor

Parameters:

roundEnv - The RoundEnvironment.

annotation - The annotation TypeElement.

element - The annotated Element.

process

public void process(Set<Class<?>> set,
                    JavaFileManager fm)
             throws Exception

Description copied from interface: ClassFileProcessor

Processor alternate entry point.

Specified by:

process in interface ClassFileProcessor

Parameters:

set - The Set of Classes to analyze.

fm - The configured JavaFileManager (for writing output files).

Throws:
