IWMSClassObject Interface

The server sends your plug-in a pointer to an IWMSClassObject interface when it calls the IWMSBasicPlugin::InitializePlugin method. You can use this pointer to create the following objects for internal use by your custom plug-in:

• The IWMSCommandContextIWMSCommandContext Interface contains methods that enable your plug-in to retrieve and specify name-value pairs that describe client requests and server responses. For more information, see Command Context.

• The IWMSContentDescriptionList interface contains methods that enable your plug-in to manage a Content Description Context for each item in a playlist.

• The IWMSContextIWMSContext Interface contains methods that enable your plug-in to retrieve and specify general context values. For more information, see Contexts.

• The IWMSDataContainerVersionIWMSDataContainerVersion Interface contains methods that enable your plug-in to specify and retrieve information about cached content and to compare the content to that stored on an origin server.

• The IWMSPacketIWMSPacket Interface contains methods that enable you to manage the buffers, attributes, and headers of a data packet.

• The IWMSPacketListIWMSPacketList Interface contains methods that enable you to manage a data packet list. Typically, this is used by data source plug-ins.

• The IWMSStreamHeaderIWMSStreamHeader Interface contains methods that enable your plug-in to specify and retrieve header information about a Windows Media stream.

• The IWMSStreamHeaderListIWMSStreamHeaderList Interface contains a collection of IWMSStreamHeader interfaces.

In addition to the methods inherited from IUnknown, the IWMSClassObject interface exposes the following methods.
