An object of this type describes the location of an
actual field in an actual record (unlike a
ibp-field-def, which talks about field
positions within an arbitrary tail). It has three
Position of the first character in the field, as an emacs position type.
Position just past the last character in the field. If the field is incomplete, this is the position just after the completed part.
For fields whose default content is spaces, this is
nil; otherwise it is the default
content from the appropriate
Here's the definition:
;; - - - - - c l a s s i b p - f i e l d - o b j e c t (defun ibp-field-object (beg end filler) "Constructor for a field object, representing the location of a field. [ if (beg is the position of the start of a field) and (end is the position of the end of a field, which may be beyond the end of its line) and (filler is the default contents of the field, or nil if the default is blank) -> return an ibp-field-object representing those values ] " (vector beg end filler))
These accessor functions extract the components of the object:
(defun ibp-field-beg (ibp-field-object) (elt ibp-field-object 0)) (defun ibp-field-end (ibp-field-object) (elt ibp-field-object 1)) (defun ibp-field-filler (ibp-field-object) (elt ibp-field-object 2))
