Like an array, a collection associates a set of objects or values as a logical group and provides access to them by index. However, most collection objects are read-only. You do not assign objects to them yourself—their contents update automatically as objects are created or deleted.
The index numbering of a collection starts with 1, not 0.
- ItemCollection object All of the items (imported files, folders, solids, and so on) found in the Project panel.
- LayerCollection object All of the layers in a composition.
- OMCollection object All of the Output Module items in the project.
- RQItemCollection object All of the render-queue items in the project.
