TOC Collections
This is a machine generated list of the collection objects defined by SketchUp classes. The links in this document are machine generated, so some may not exist.

The criteria is that a class has .each defined as a public method. Note that
.each is an Array method and is not a method of Enumerable.
The classes can be divided into two groups:
'Live' read-only collections of objects, with factory methods to add new members. All include Enumerable, and all suport indexed retrieval, although order/position may vary from call to call.
'Hash' like collections where items cannot be added or removed. An example would be RenderingOptions.
Typically 'Live' collections have a .length property that is more of a method
or a numeric object (as opposed to a value). The following code shows a change
in the length of entities as the two faces are added.
am_ents = Sketchup.active_model.entities
s = 300
f1 = [ 0, 0, 0 ] , [ 0, s, 0 ] , [ s, s, 0 ] , [ s, 0, 0 ]
f2 = [ 0, 0, s ] , [ 0, s, s ] , [ s, s, s ] , [ s, 0, s ]
puts "am_ents.length = #{am_ents.length}"
am_ents.add_face( f1 )
puts "am_ents.length = #{am_ents.length}"
am_ents.add_face( f2 )
puts "am_ents.length = #{am_ents.length}"
What this means is that it will often be faster to make a copy of the collection
using .to_a if you are looping thru the whole collection. .grep() will do the
same thing if you only need a subset. You may find .to_a.grep() to be faster.
