Member Function Documentation

ExtendedInterface ( TUid )

void *

ExtendedInterface

(

TUid

aInterfaceId

)

[virtual]

For future expansion. Any overriders must base-call if aInterface is unrecognized.

WARNING: Function for internal use ONLY. Compatibility is not guaranteed in future releases.

Parameter	Description
aInterfaceId	The ID of the interface to return.

Returns: A pointer to the extension interface.

NewL ( TUid )

CShaperFactory *

NewL

(

TUid

aInterfaceImplUid

)

[static, inline]

Uses ECOM plug-in framework to instantiate the shaper factory interface implementation given its implementation UID.

Parameter	Description
aInterfaceImplUid	The UID of the interface implementation required

Returns: CShaperFactory* A pointer to a CShaperFactory object.

NewShaperL ( CBitmapFont , TInt, TInt, RHeap )

CShaper *	NewShaperL	(	CBitmapFont *	aFont,
			TInt	aScript,
			TInt	aLanguage,
			RHeap *	iHeap
		)	[pure virtual]

Create a shaper if possible, for typeface aFaceIndex within file aFileName.

Parameter	Description
aFont	The font to be shaped.
iHeap	The heap to use for constructing the shaper.

Returns: 0 If the font is not understood or inappropriate for any shaper that might be constructed by this class, otherwise returns the newly-constructed shaper on iHeap.
