Docs For Class ASF

Description

This class represents a file in Advanced Systems Format (ASF) as described in

The Advanced Systems Format (ASF) Specification. It is a file format that can contain various types of information ranging from audio and video to script commands and developer defined custom streams.

The ASF file consists of code blocks that are called content objects. Each of these objects have a format of their own. They may contain other objects or other specific data. Each supported object has been implemented as their own classes to ease the correct use of the information.
