Detailed Description

Client-side interface to the server-side animation DLL.

This is the client side class matching the server side CAnimDLL class. It provides functions to create, load, close and destroy a server-side CAnimDll object.

Constructor & Destructor Documentation

RAnimDll ( )

IMPORT_CRAnimDll()

Default constructor.

RAnimDll is a lightweight class which can be allocated as a non-pointer member. This constructor is provided to allow such a member to be instantiated while its owner is constructed.

Note that an RAnimDll constructed without a reference to a window server session is invalid.

RAnimDll ( RWsSession & )

IMPORT_CRAnimDll(RWsSession &aWs)

Valid constructor.

To be useable, an animation DLL should always be constructed with a reference to a window server session as argument.

Parameters
aWsWindow server session to use.

~RAnimDll ( )

IMPORT_C~RAnimDll()[virtual]

Empty virtual destructor.

Destroy() should be used to instead of this function to destroy both this object and the server-side CAnimDll object.

See also: Destroy() Close()

Member Function Documentation

Close ( )

IMPORT_C voidClose()[virtual]

Closes an animation DLL.

Use this function to close a polymorphic DLL which was previously loaded on the server. Cleans up and frees all resources belonging to the DLL but does not delete it. Closing is in accordance with the RLibrary mechanism.

Load() and Close() are symmetrical operations. A DLL can be re-loaded after a close has been called on it.

To both close and delete a previously loaded DLL, use Destroy().

Destroy ( )

IMPORT_C voidDestroy()

Closes and deletes a previously loaded polymorphic DLL.

This function is equivalent to calling this->Close() followed by delete this, in accordance with the RLibrary mechanism provided for managing polymorphic DLLs.

Load ( const TDesC & )

IMPORT_C TIntLoad(const TDesC &aFileName)

Instructs the server to load an animation DLL.

Use this function to pass the name of a polymorphic DLL, the animation DLL, for loading on the server side. Loading is in accordance with the RLibrary mechanism. The DLL must conform to the interface defined by the window server, otherwise an error will result. For requirements, see the description of CAnimDll.

Load() and Close() are symmetrical operations. A DLL can be re-loaded after a close has been called on it.

This function always causes a flush of the window server buffer.

Parameters
aFileNameFilename of the DLL to load.
Return Value
KErrNone if successful, otherwise one of the system-wide error codes.
Panic Codes
TW32Panic17 in debug builds if called on an already constructed object.
