@interface PSPDFInstantCommentMarkerAnnotation : PSPDFNoteAnnotation


class InstantCommentMarkerAnnotation : NoteAnnotation

The root annotation of a freely placed thread of Instant Comments.

In contrast to regular note annotation, comment markers do not have contents of their own. Instead they serve as the anchor for freely placing a comment thread on a page. The actual contents are then represented as an array of comments — objects that have no geometric or appearance-defining properties of their own.

Another difference from regular note annotations is that Instant does not support the author state model defined in the PDF standard. As a result, comment markers will always report an “unspecified” author state and ignore any corresponding updates.
