All Implemented Interfaces:

Comparable<AnnotationType>

public class AnnotationType
extends Object
implements Comparable<AnnotationType>

An AnnotationType describes a certain type of annotations; they are generally distinguished by a name, an id, and an optional data type.

If an AnnotationType has a DataType, this means that Annotations of that type are allowed to have a FieldValue of the given DataType as an optional payload.
