| class CMMFDataBuffer : public CMMFBuffer |
This class is an abstract class for databuffers that can be presented in the form of a descriptor. A constructor is provided which instantiates a CMMFDescriptorBuffer buffer by default.

| CMMFDataBuffer | ( | TUid | aType | ) | [protected, inline] |
Protected constructor.
| TUid aType |
| TUint | BufferSize | ( | ) | const [pure virtual] |
Returns the buffer size, in bytes.
This is a virtual function that each derived class must implement.
The buffer size in bytes.
| TDes8 & | Data | ( | ) | [pure virtual] |
Returns a reference to the data contained in the buffer (non const version).
This is a virtual function that each derived class must implement.
A reference to the buffer.
| const TDesC8 & | Data | ( | ) | const [pure virtual] |
Returns a reference to the data contained in the buffer (const version).
This is a virtual function that each derived class must implement.
A reference to the buffer.
| void | SetRequestSizeL | ( | TInt | aSize | ) | [pure virtual] |
Sets the request size.
Used where a component, such as a data source, may not be able to write to the entire maximum length of the buffer (variable bit rate codecs for example).
This is a virtual function that each derived class must implement.
| TInt aSize | The requested size, in bytes. |
