Method Detail

getResource

protected abstract URL getResource(String className)

loadClass

protected abstract Class<?> loadClass(String fixedName)
                               throws ClassNotFoundException

Throws:

ClassNotFoundException

getAnnotatedClassNames

public List<String> getAnnotatedClassNames()

Specified by:

getAnnotatedClassNames in interface IAnnotationFinder

link

public AbstractFinder link()
                    throws IOException

The link() method must be called to successfully use the findSubclasses and findImplementations methods

Returns:

Throws:

IOException

isAnnotationPresent

public boolean isAnnotationPresent(Class<? extends Annotation> annotation)

Specified by:

isAnnotationPresent in interface IAnnotationFinder

getClassesNotLoaded

public List<String> getClassesNotLoaded()

Returns a list of classes that could not be loaded in last invoked findAnnotated* method.

The list will only contain entries of classes whose byte code matched the requirements of last invoked find* method, but were unable to be loaded and included in the results.

The list returned is unmodifiable. Once obtained, the returned list will be a live view of the results from the last findAnnotated* method call.

This method is not thread safe.

Specified by:

getClassesNotLoaded in interface IAnnotationFinder

Returns:

an unmodifiable live view of classes that could not be loaded in previous findAnnotated* call.

findAnnotatedPackages

public List<Package> findAnnotatedPackages(Class<? extends Annotation> annotation)

Specified by:

findAnnotatedPackages in interface IAnnotationFinder

findAnnotatedClasses

public List<Class<?>> findAnnotatedClasses(Class<? extends Annotation> annotation)

Specified by:

findAnnotatedClasses in interface IAnnotationFinder

findMetaAnnotatedClasses

public List<Annotated<Class<?>>> findMetaAnnotatedClasses(Class<? extends Annotation> annotation)

Specified by:

findMetaAnnotatedClasses in interface IAnnotationFinder

findInheritedAnnotatedClasses

public List<Class<?>> findInheritedAnnotatedClasses(Class<? extends Annotation> annotation)

Naive implementation - works extremelly slow O(n^3)

Specified by:

findInheritedAnnotatedClasses in interface IAnnotationFinder

Parameters:

annotation -

Returns:

list of directly or indirectly (inherited) annotated classes

findAnnotatedMethods

public List<Method> findAnnotatedMethods(Class<? extends Annotation> annotation)

Specified by:
