Warning

Items order does not represent actual priority order! Items in each section are sorted according to @Priority annotation and then by name, but @Custom qualification priority is ignored (and so user extensions and default one may be shown in incorrect order). Report sorting applied only for consistency (always show the same order) - it's a trade off.

Common markers

Markers are shown at the end of extension line. The following markers are common for all extension types.

Filter

Jersey extension scope may be reduced with @NameBinding annotation. Custom annotation may be created (declared as @NameBinding):

@NameBinding
@Target(ElementType.TYPE)
@Retention(RetentionPolicy.RUNTIME)
public @interface FilterAnn {}

Now if extension will be annotated with it:

@Provider
@FilterAnn
public class ExMapper implements ExceptionMapper<IOException> {}

Will be applied only to resources, annotated with @FilterAnn.

Report will identify scoped extensions with marker:

IOException                    ExMapper                     (r.v.d.g.d.r.j.FilterMarkerRenderTest) *only @FilterAnn

Lazy

Extensions annotated with @LazyBinding are identified with marker:

IOException                    ExMapper                     (r.v.d.g.d.r.j.LazyRenderTest) *lazy

Jersey managed

Extensions, managed by HK2 are also identified with marker:

@Ann                            HKInjectionResolver          (r.v.d.g.c.h.s.hk)         *jersey managed

Exception mappers

Extended exception mappers (these mappers may decide if they accept exception handling):

@Provider
public class ExtMapper implements ExtendedExceptionMapper<IOException> {
    @Override
    public boolean isMappable(IOException exception) {
        return false;
    }

    @Override
    public Response toResponse(IOException exception) {
        return null;
    }
}

Are identified in report:

OException                    ExtMapper                    (r.v.d.g.d.r.j.ExtendedExceptionMapperRenderTest) *extended

Report customization

Report is implemented as guicey event listener and provide additional customization options, so if default configuration (from shortcut methods above) does not fit your needs you can register listener directly with required configuration.

For example, to show only exception mappers:

listen(new JerseyConfigDiagnostic(new JerseyConfig()
                    .showExceptionMappers()))

Report rendering logic may also be used directly as report provide separate renderer object implementing ReportRenderer. Renderer not bound to guice context and assume direct instantiation.
