Edit that contains list of Edits lined up in the list chronologically as they were executed.

A base interface for various edits (annotations, bookmarks, etc.). It's managed by the com.pspdfkit.undo.UndoManager, providing a mechanism for undoing/redoing these edits.

Common base class for undo edits that might require a page navigation and therefore need to store a pageIndex. Currently used for com.pspdfkit.undo.edit.annotations.AnnotationEdit and com.pspdfkit.undo.edit.contentediting.ContentEditingEdit
