GendL Application - STANDARD-SEQUENCE

Object: STANDARD-SEQUENCE (The :GENDL Package)

Description

A standard sequence quantification is generated as a result of specifying :sequence (:size [number-expression])) in an :objects specification. Unlike a variable-sequence quantification (specified with :sequence (:indices ...))), elements cannot be surgically inserted or deleted from a standard sequence. If a value upon which the [number-expression] depends becomes modified, each member of the sequence will be reinstantiated as it is demanded.

Input Slots (optional)

HIDDEN? [from VANILLA-MIXIN] boolean*
Indicates whether the object should effectively be a hidden-object even if specified in :objects. Default is nil.

ROOT [from VANILLA-MIXIN] gdl instance*
The root-level node in this object's ``tree'' (instance hierarchy).

SAFE-CHILDREN [from VANILLA-MIXIN] list of gdl instances*
All objects from the :objects specification, including elements of sequences as flat lists. Any children which throw errors come back as a plist with error information

STRINGS-FOR-DISPLAY [from VANILLA-MIXIN] string or list of strings*
Determines how the name of objects of this type will be printed in most places. This defaults to the name-for-display (generally the part's name as specified in its parent), followed by an index number if the part is an element of a sequence.

VISIBLE-CHILDREN [from VANILLA-MIXIN] list of gdl instances*
Additional objects to display in Tatu tree. Typically this would be a subset of hidden-children. Defaults to NIL.

Computed Slots

FIRST [from QUANTIFICATION] gdl object
Returns the first element of the aggregate.

LAST [from QUANTIFICATION] gdl object
Returns the last element of the aggregate.
