The QCComposition class represents a Quartz Composer composition that either:
- comes from the system-wide composition repository (/Library/Compositions and ~/Library/Compositions) where it can be accessed by any application through the methods of the QCCompositionRepository class
- is created from an arbitrary source (typically a file on disk) using one of its methods
This class cannot be subclassed.
A QCComposition object has the following information associated with it and that you can obtain by using the appropriate method of the QCComposition class:
- Attributes include the name and description of the composition, copyright information, and whether or not its provided by OS X (built-in).
- The protocols that the composition conforms to. A composition protocol defines a set of required and optional input parameters and output results.
Many methods of the QCRenderer, QCCompositionLayer, and QCView classes take a QCComposition object as a parameter.
This is an abstract class. You can't create an instance, but you can get one from various plugin functions.
