All Implemented Interfaces:

Annotations

public final class AnnotationMap
extends Object
implements Annotations

Simple helper class used to keep track of collection of Jackson Annotations associated with annotatable things (methods, constructors, classes). Note that only Jackson-owned annotations are tracked (for now?).
