Examples of org.mule.util.scan.ClasspathScanner

org.mule.util.scan.ClasspathScanner
This class can be used to scan the classpath for classtypes (or interfaces they implement) or for annotations on the classpath. The type of scanner used depends on the class type passed in. There are currently 3 types of scanner;
- {@link InterfaceClassScanner} - will search for all class that are assignableto the interface provided
- {@link ImplementationClassScanner} - will search for all classes that extend abase type
- {@link AnnotationsScanner} - will search for classes with specificannotations, this can also seach for meta annotations
This scanner uses ASM to search class byte code rather than the classes themselves making orders of magnitude better performance and uses a lot less memory. ASM seems to be the fasted of the byte code manipulation libraries i.e. JavaAssist or BCEL Note that the scanner will not scan inner or anonymous classes.

        String[] paths = convertPackagesToPaths(basepackages);
        if(logger.isInfoEnabled())
        {
            logger.info("Scanning for annotations using the following paths: " + StringMessageUtils.toString(paths));
        }
        return new ClasspathScanner(classLoader, paths);
    }
