IMLDSPlugin (Compact 7)

3/12/2014

This interface is implemented by the data source plug-in and is used by the plug-in manager to initialize and control the data source plug-in modules.

Methods

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

• IMLDSPlugin::Init
  Initializes the data source plug-in.

• IMLDSPlugin::GetDataSources
  Implemented by the data source plug-in to return the number of attached data sources connected to the Media Library.

• IMLDSPlugin::GetPluginCaps
  Returns a DWORD that is composed of multiple MLDataSourceFlags values to indicate what type of operations the data source supports.

• IMLDSPlugin::UpdateWatchList
  Adds or removes a location to the list of monitored locations for the data source plug-in.

• IMLDSPlugin::GetWatchListCount
  Returns the number of locations currently monitored by the data source plug-in.

• IMLDSPlugin::GetWatchList
  Returns the list of locations currently monitored by the data source plug-in.

• IMLDSPlugin::GetFileList
  Calls the IMLDSItemSink::ProcessFile method back for each file.

Remarks

The plug-in manager creates and owns the data source plug-in objects. The plug-in manager calls the methods on this interface directly to retrieve the file list, manage the push queue information, and describe the data sources.

You must register your data source plug-in with the Media Library for the plug-in manager to create the plug-in. For more information on registering your plug-in, see Media Library Registry Settings.

When to Implement

Implement this interface if you have a data source type that is not supported by the Media Library. For more information on the data source types, see the MLDataSourceId enumeration.
