Class AnnotationAcceptingListener

java.lang.Object

org.glassfish.jersey.server.internal.scanning.AnnotationAcceptingListener

All Implemented Interfaces:

ResourceProcessor

public final class AnnotationAcceptingListener
extends Object
implements ResourceProcessor

A scanner listener that processes Java class files (resource names ending in ".class") annotated with one or more of a set of declared annotations.

Java classes of a Java class file are processed, using ASM, to ascertain if those classes are annotated with one or more of the set of declared annotations.

Such an annotated Java class of a Java class file is loaded if the class is public or is an inner class that is static and public.

Method Detail

newJaxrsResourceAndProviderListener

public static AnnotationAcceptingListener newJaxrsResourceAndProviderListener()

Create a scanning listener to check for Java classes in Java class files annotated with Path or Provider.

Returns:

new instance of AnnotationAcceptingListener which looks for Path or Provider annotated classes.

newJaxrsResourceAndProviderListener

public static AnnotationAcceptingListener newJaxrsResourceAndProviderListener(ClassLoader classLoader)

Create a scanning listener to check for Java classes in Java class files annotated with Path or Provider.

Parameters:

classLoader - the class loader to use to load Java classes that are annotated with any one of the annotations.

Returns:

new instance of AnnotationAcceptingListener which looks for Path or Provider annotated classes.

getAnnotatedClasses

public Set<Class<?>> getAnnotatedClasses()

Get the set of annotated classes.

Returns:

the set of annotated classes.

accept

public boolean accept(String name)

Description copied from interface: ResourceProcessor

Accept a scanned resource.

Specified by:

accept in interface ResourceProcessor

Parameters:

name - the resource name.

Returns:

true if the resource is accepted for processing, otherwise false.

process

public void process(String name,
                    InputStream in)
             throws IOException

Description copied from interface: ResourceProcessor
