Nested Classes

Modifier and Type	Class and Description
static class	AnnotationConfiguration.ClassInheritanceMap
class	AnnotationConfiguration.ContainerClassNameResolver ContainerClassNameResolver Checks to see if a classname belongs to a hidden or visible package when scanning for annotations and thus whether it should be excluded from consideration or not.
class	AnnotationConfiguration.ParserTask ParserTask Task to executing scanning of a resource for annotations.
class	AnnotationConfiguration.ServletContainerInitializerComparator ServletContainerInitializerComparator Comparator impl that orders a set of ServletContainerInitializers according to the list of classnames (optionally containing a "*" wildcard character) established in a ServletContainerInitializerOrdering.
class	AnnotationConfiguration.ServletContainerInitializerOrdering ServletContainerInitializerOrdering A list of classnames of ServletContainerInitializers in the order in which they are to be called back.
class	AnnotationConfiguration.TimeStatistic TimeStatistic Simple class to capture elapsed time of an operation.
class	AnnotationConfiguration.WebAppClassNameResolver WebAppClassNameResolver Checks to see if a classname belongs to hidden or visible packages when scanning, and whether a classname that is a duplicate should override a previously scanned classname.
