Detailed Description

This interface is used to create and manage Library Bosses. It also is used to obtain interfaces to Library utilities.

Member Function Documentation

virtual ILibrary* ILibraryService::CreateLibrary ( )

pure virtual

Create a new library object and return a pointer to it. The library service keeps a reference to the library, so the caller must call ReleaseLibrary when finished with it to cause the Library Service to release it.

Returns

interface pointer to library created

virtual int32 ILibraryService::NumLibraries ( ) const

pure virtual

Get the number of library objects currently in use.

Returns

the number of libraries

virtual ILibraryCmdUtils* ILibraryService::QueryLibraryCmdUtils ( ) const

pure virtual

Get the Library Command Utilities interface.

Returns

interface pointer to ILibraryCmdUtils

virtual ILibraryDragDropUtils* ILibraryService::QueryLibraryDDUtils ( ) const

pure virtual

Get the Library Drag&Drop Utilities interface.

Returns

interface pointer to ILibraryDragDropUtils

virtual ILibrary* ILibraryService::QueryNthLibrary ( int32  n ) const

pure virtual

Get the Nth library.

Parameters

n	IN library index

Returns

interface pointer to nth library

virtual void ILibraryService::ReleaseLibrary ( ILibrary *  library )

pure virtual

Call when finished with using a library object. The library will most likely be destructed during this call.

Parameters

library

IN the library to release
