IMPORT_C void | RemoveImageData(TInt) |
Class to manage lists of frame and image block data.
IMPORT_C | ~CFrameImageData | ( | ) |
Destructor for this class.
If ownership of the image data was transfered, it is now destroyed.
IMPORT_C CFrameImageData * | AllocL | ( | ) | const |
Creates a full copy of the objects data. Ownership is transferred to the caller.
IMPORT_C TInt | AppendFrameData | ( | const TFrameDataBlock * | aEntry | ) |
Adds a pointer to a frame data block to the end of the internally held list.
Parameters | |
---|---|
aEntry | The frame data block pointer to be inserted. |
Stores the supplied image data in a newly allocated entry in the image buffer array.
Parameters | |
---|---|
aImageBuffer | The HBufC8 pointer to take ownership of. |
IMPORT_C TInt | AppendImageData | ( | const TImageDataBlock * | aEntry | ) |
Adds a pointer to an image data block to the end of the internally held list.
Parameters | |
---|---|
aEntry | The image data block pointer to be inserted. |
IMPORT_C TInt | FrameDataCount | ( | ) | const |
Returns the number of frame data blocks in the internally held list.
IMPORT_C const TFrameDataBlock * | GetFrameData | ( | TInt | aIndex | ) | const |
Const version.
Returns the frame data block at the given position from the internally held list.
Parameters | |
---|---|
aIndex | The position of the frame data block to retrieve. Must be in the range 0 to FrameDataCount(). |
IMPORT_C TFrameDataBlock * | GetFrameData | ( | TInt | aIndex | ) |
Non const version.
Returns the frame data block at the given position from the internally held list.
Parameters | |
---|---|
aIndex | The position of the frame data block to retrieve. Must be in the range 0 to FrameDataCount(). |
IMPORT_C const TImageDataBlock * | GetImageData | ( | TInt | aIndex | ) | const |
Returns the image data block at the given position from the internally held list.
Parameters | |
---|---|
aIndex | The position of the image data block to retrieve. Must be in the range 0 to ImageDataCount(). |
IMPORT_C TImageDataBlock * | GetImageData | ( | TInt | aIndex | ) |
Returns the image data block at the given position from the internally held list.
Parameters | |
---|---|
aIndex | The position of the image data block to retrieve. Must be in the range 0 to ImageDataCount(). |
IMPORT_C TInt | ImageDataCount | ( | ) | const |
Returns the number of image data blocks in the internally held list.
IMPORT_C TInt | InsertFrameData | ( | const TFrameDataBlock * | aEntry, |
TInt | aPos | |||
) |
Inserts a pointer to a frame data block into the internally held list in front of the item at position aPos.
See also: CFrameImageData::FrameDataCount()
Parameters | |
---|---|
aEntry | The frame data block pointer to be inserted. |
aPos | The position at which to insert the pointer into the internal list. Must not be less than 0 or greater than the value returned by CFrameImageData::FrameDataCount(). |
IMPORT_C TInt | InsertImageData | ( | const TImageDataBlock * | aEntry, |
TInt | aPos | |||
) |
See also: CFrameImageData::ImageDataCount().
Inserts a pointer to an image data block into the internally held list in front of the item at position aPos.
Parameters | |
---|---|
aEntry | The image data block pointer to be inserted. |
aPos | The position at which to insert the pointer into the internal list. Must not be less than 0 or greater than the value returned by CFrameImageData::ImageDataCount(). |
IMPORT_C CFrameImageData * | NewL | ( | ) | [static] |
Static factory function for creating instances of CFrameImageData. The managed list of image data is created/destroyed internally.
IMPORT_C CFrameImageData * | NewL | ( | CImageDataArray & | aImageData, |
TBool | aImageDataOwner = EFalse | |||
) | [static] |
Static factory function for creating instances of CFrameImageData.
The managed list of image data is created internally. If a data owner is specified then the responsibility for destroying the managed list is that of the owner. If no owner is specified the managed list is destroyed internally.
Parameters | |
---|---|
aImageData | A reference to an externally created CImageDataArray. |
aImageDataOwner | If set to true, responsibility for deleting CImageDataArray is passed to the CFrameImageData object. |
IMPORT_C void | RemoveFrameData | ( | TInt | aIndex | ) |
Removes a pointer to a frame data block at position aIndex from the internally held list.
See also: CFrameImageData::FrameDataCount().
Parameters | |
---|---|
aIndex | Position of the pointer to delete. Must not be less than 0 or greater than the value returned by CFrameImageData::ImageDataCount(). |
IMPORT_C void | RemoveImageData | ( | TInt | aIndex | ) |
Removes a pointer to an image data block at position aIndex from the internally held list.
See also: CFrameImageData::ImageDataCount().
Parameters | |
---|---|
aIndex | The index into the list. Must not be less than 0 or greater than the value returned by CFrameImageData::ImageDataCount(). |
