Detailed Description

A generic class containing fields of names and values.

A Gst::Structure is a collection of key/value pairs. The keys are expressed as GQuarks and the values can be of any GType.

In addition to the key/value pairs, a Gst::Structure also has a name. The name starts with a letter and can be folled by letters, numbers and any of "/-_.:".

Gst::Structure is used by various GStreamer subsystems to store information in a flexible and extensible way. A Gst::Structure does not have a refcount because it usually is part of a higher level object such as Gst::Caps. It provides a means to enforce mutability using the refcount of the parent.
