Collection objects serve as merely a wrapper for a cell-array of LTPDA User Objects. The point of this is to provide a way to put together user objects of different classes in to a collection which can be saved/loaded/submitted/retrieved, etc.
You can create a collection object like:
>> c = collection ---- collection 1 ---- name: none num objs: 0 description: UUID: a339a156-956b-4657-96ef-9ea4feef8101 ----------------------
>> c.addObjects(ao(1)) M: running ao/ao M: constructing from values M: running collection/addObjects M: running ao/char ---- collection 1 ---- name: none num objs: 1 01: ao | None/cdata(Ndata=[1x1]) description: UUID: c1f0200f-ad98-4fd6-beae-2dcdabb33515 ----------------------
>> c.addObjects(pzmodel(1, 10, 100), mfir()) M: running collection/addObjects M: running ao/char ---- collection 1 ---- name: none num objs: 3 01: ao | None/cdata(Ndata=[1x1]) 02: pzmodel | pzmodel(None) 03: mfir | none(fs=, ntaps=0.00, a=[]) description: UUID: e7f02380-5650-4788-b819-f7fa7ee50a7d ----------------------
You can then extract objects from the collection using getObjectAtIndex or get an array of all objects of a particular class using getObjectsOfClass. Objects can be removed from the collection using removeObjectAtIndex.
Since a collection object is an LTPDA User Object, it has history tracking capabilities. That means that everytime you
add or remove an object to/from the collection, a history step is added. For example, the history of our collection above looks like:
