Class CImageEncodeConstruct

class CImageEncodeConstruct : public CBase;

Description

Provides functions related to constructing encoders.

Objects of this class are loaded by ECOM, and it is this class which is responsible for instantiating the encoder plugins. Plugin writers must derive their own plugin specific variants. The derived class is responsible for defining its own factory function to create instances of itself.

Derivation

• CBase - Base class for all classes to be instantiated on the heap.

• CImageEncodeConstruct - Provides functions related to constructing encoders.

IMPORT_C ~CImageEncodeConstruct();

Description

Destructor

protected: IMPORT_C CImageEncodeConstruct();

Description

Default constructor

protected: IMPORT_C void ConstructL();

Description

Second stage constructor. This should be called during construction of the derived class.

IMPORT_C TUid ImplementationUid() const;

Description

Retrieve the encoder implementation UID.

Return value

TUid The implementation UID.

IMPORT_C virtual CImageEncoder* NewEncoderL() const;

Description

Default version creates a basic CImageEncoder.

Return value

CImageEncoder * Pointer to a fully constructed CImageEncoder object.

virtual CImageEncoderPlugin* NewPluginL() const=0;

Description

Creates new concrete CImageEncoderPlugin object.

This is a virtual function that each derived class must implement.

Return value

CImageEncoderPlugin * A pointer to fully constructed CImageEncoderPlugin.

IMPORT_C virtual TBool RequestThread() const;

Description

Requests a threaded encode.

Note: The default version of this virtual function returns EFalse and does not request a threaded encode.

Return value

TBool
