jdk.internal.jvmci.options.processor

Class OptionProcessor

java.lang.Object

javax.annotation.processing.AbstractProcessor

jdk.internal.jvmci.options.processor.OptionProcessor

All Implemented Interfaces:

Processor

@SupportedAnnotationTypes(value="jdk.internal.jvmci.options.Option")
public class OptionProcessor
extends AbstractProcessor

Processes static fields annotated with Option. An Options service is generated for each top level class containing at least one such field. The name of the generated class for top level class com.foo.Bar is com.foo.Bar_Options. The build system is expected to create the appropriate entries in META-INF/services/ such that these service objects can be retrieved as follows:

 ServiceLoader<Options> sl = ServiceLoader.load(Options.class);
 for (Options opts : sl) {
     for (OptionDescriptor desc : sl) {
         // use desc
     }
 }
