Class CachedAnnotationScanner

  • public class CachedAnnotationScanner
extends java.lang.Object
    This classes provides a list of static methods delegating annotation scanning to AnnotationScanner and caching its results. A cache entry for each combination of packagePrefix and ClassLoader will be created. Calling this class for non-bounded sets of combinations will cause memory issues. Please be therefore aware of what you're doing when using this class
