GendL Application - matrix-sequence

Object: matrix-sequence (The :gendl Package)

Mixins: standard-sequence, vanilla-mixin

Description

A matrix sequence quantification is generated as a result of specifying :sequence (:matrix direction-keyword number direction-keyword number)) in an :objects specification. The direction-keywords can be one of :lateral, :longitudinal, and :vertical. The items will be arranged spread out evenly in the directions specified. Centers can also be provided explicitly based on the indices. The indices to a matrix sequence consist of a list of numbers rather than a single number as with a normal sequence.

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.
