Examples of org.apache.commons.weaver.model.ScanResult

org.apache.commons.weaver.model.ScanResult
Encapsulates the result of scanning based on a {@link ScanRequest}. The scan results are available in a structure corresponding to the Java class hierarchy; i.e.:
```
 package |_class |_field |_method | |_method parameter |_constructor |_constructor parameter 
```
The tree of results can be iterated in this manner using {@link #getPackages()}. However, if a given {@link Weaver} is known not tohandle packages but some other element, convenience methods are provided here giving direct access to the various elements that may have been discovered.

        final ScanRequest scanRequest =
            new ScanRequest().add(WeaveInterest.of(TestAnnotation.class, ElementType.TYPE))
                .add(WeaveInterest.of(TestAnnotation.class, ElementType.METHOD))
                .addSupertypes(AbstractTestBean.class, TestBeanInterface.class);


        final ScanResult scanResult = scanner.scan(scanRequest);


        for (WeavableClass<?> weavableClass : scanResult.getClasses().with(TestAnnotation.class)) {
            if (wovenClasses.add(weavableClass.getTarget())) {
                result = true;
            }
        }
        for (WeavableMethod<?> weavableMethod : scanResult.getMethods().with(TestAnnotation.class)) {
            if (wovenMethods.add(weavableMethod.getTarget())) {
                result = true;
            }
        }
        for (WeavableClass<?> weavableClass : scanResult.getClassesAssignableTo(TestBeanInterface.class)) {
            if (implementors.add(weavableClass.getTarget())) {
                result = true;
            }
        }
        for (WeavableClass<?> weavableClass : scanResult.getClassesAssignableTo(AbstractTestBean.class)) {
            if (subclasses.add(weavableClass.getTarget())) {
                result = true;
            }
        }
