Method readElementValues

src/jvm/clojure/asm/ClassReader.java:2742–2769

Reads the element values of a JVMS 'annotation' structure and makes the given visitor visit them. This method can also be used to read the values of the JVMS 'array_value' field of an annotation's 'element_value'. @param annotationVisitor the visitor that must visit the values. @param annotationOff

      final int annotationOffset,
      final boolean named,
      final char[] charBuffer)

   * @return the end offset of the JVMS 'annotation' or 'array_value' structure.
