 * ClassGraph scans the classpath or module path using [carefully optimized multithreaded code](https://github.com/classgraph/classgraph/wiki/How-fast-is-ClassGraph) for the shortest possible scan times, and it runs as close as possible to I/O bandwidth limits, even on a fast SSD.
 * ClassGraph handles more [classpath specification mechanisms](https://github.com/classgraph/classgraph/wiki/Classpath-specification-mechanisms) found in the wild than any other classpath scanner, making code that depends upon ClassGraph maximally portable.
 * ClassGraph can scan the classpath and module path either at runtime or [at build time](https://github.com/classgraph/classgraph/wiki/Build-Time-Scanning) (e.g. to implement annotation processing for Android).
+* ClassGraph parses most of the useful metadata in a classfile, including methods, fields, annotations, outer/inner class containment relationships, and even [type annotations](https://docs.oracle.com/javase/tutorial/java/annotations/type_annotations.html).
 * ClassGraph can [find classes that are duplicated or defined more than once in the classpath or module path](https://github.com/classgraph/classgraph/wiki/Code-examples#find-all-duplicate-class-definitions-in-the-classpath-or-module-path), which can help find the cause of strange class resolution behaviors.
 * ClassGraph can [create GraphViz visualizations of the class graph structure](https://github.com/classgraph/classgraph/wiki/ClassInfo-API#generating-a-graphviz-dot-file-for-class-graph-visualization), which can help with code understanding: (click to enlarge | [see graph legend here](https://github.com/classgraph/classgraph/blob/master/src/test/java/com/xyz/classgraph-fig-legend.png))
