Detailed 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.

Member Function Documentation

ConstructL ( )

IMPORT_C void

ConstructL

(

)

[protected]

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

ImplementationUid ( )

IMPORT_C TUid

ImplementationUid

(

)

const

Retrieve the encoder implementation UID.

Return Value: The implementation UID.

NewEncoderL ( )

IMPORT_C CImageEncoder *

NewEncoderL

(

)

const [virtual]

Default version creates a basic CImageEncoder.

Return Value: Pointer to a fully constructed CImageEncoder object.

NewPluginL ( )

CImageEncoderPlugin *

NewPluginL

(

)

const [pure virtual]

Creates new concrete CImageEncoderPlugin object.

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

Return Value: A pointer to fully constructed CImageEncoderPlugin.

RequestThread ( )

IMPORT_C TBool

RequestThread

(

)

const [virtual]

Requests a threaded encode.

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