Type Topic Plugin Version macOS Windows Linux Console & Web iOS
class Quartz Composer MBS CocoaControls Plugin 15.1 Yes No No Yes, macOS only No
Function: The composition class.
Notes:
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.
