ParserAnnotation

ParserAnnotation is a parser class owned by Parser.java. It is primarily responsible for parsing Annotations (for classes, methods or fields).

ParserAnnotation can parse the different types of Annotation Attributes: Runtime(In)Visible Annotations (JDK 6+) Default Annotations (JDK 6+) Runtime(In)VisibleParameter Annotations (JDK 7+) Runtime(In)VisibleType Annotations (JSR308, JDK8+)
