Method Detail

findAllClassesInClasspathRoot

public static List<Class<?>> findAllClassesInClasspathRoot(URI root,
                                                           Predicate<Class<?>> classTester,
                                                           Predicate<String> classNameFilter)

Find all classes of the supplied root URI that match the specified classTester and classNameFilter predicates.

Parameters:

root - the root URI to start scanning

classTester - the class type filter; never null

classNameFilter - the class name filter; never null

Returns:

the list of all such classes found; neither null nor mutable

findAllClassesInPackage

public static List<Class<?>> findAllClassesInPackage(String basePackageName,
                                                     Predicate<Class<?>> classTester,
                                                     Predicate<String> classNameFilter)

Find all classes of the supplied basePackageName that match the specified classTester and classNameFilter predicates.

Parameters:

basePackageName - the base package name to start scanning

classTester - the class type filter; never null

classNameFilter - the class name filter; never null

Returns:

the list of all such classes found; neither null nor mutable

findMethods

public static List<Method> findMethods(Class<?> clazz,
                                       Predicate<Method> predicate,
                                       HierarchyTraversalMode traversalMode)

Find all methods of the supplied class or interface that match the specified predicate.

If you're are looking for methods annotated with a certain annotation type, consider using AnnotationSupport.findAnnotatedMethods(Class, Class, HierarchyTraversalMode).

Parameters:

clazz - the class or interface in which to find the methods; never null

predicate - the method filter; never null

traversalMode - the hierarchy traversal mode; never null

Returns:

the list of all such methods found; neither null nor mutable
