Member Functions Documentation
ForceBufferFilledL(const TSensrvChannelId)
Forces SSY to call BufferFilled() regardless of how many data items have been written to buffer. Even if no data items have yet been written, BufferFilled() must be called.
Parameters
| const TSensrvChannelId aChannelId | Channel Id to be linked to this force buffer filled message |
GetChannelDataProviderInterfaceL(TUid, TAny *&)
| void | GetChannelDataProviderInterfaceL | ( | TUid | aInterfaceUid, |
| | TAny *& | aInterface |
| | ) | [pure virtual] |
Returns a pointer to a specified interface - to allow future extension of this class without breaking binary compatibility
Parameters
| TUid aInterfaceUid | Identifier of the interface to be retrieved |
| TAny *& aInterface | A reference to a pointer that retrieves the specified interface. |
StartChannelDataL(const TSensrvChannelId, TUint8 *, TInt)
Starts asynchronous data listening. Multiple OpenChannel()-requests can be active for different channels at the same time.
Parameters
| const TSensrvChannelId aChannelId | Channel Id to be linked to this start channel data message |
| TUint8 * aBuffer | Pointer to a data buffer |
| TInt aCount | Indicates data buffer size as a count of the data objects. |
StopChannelDataL(const TSensrvChannelId)
Stops asynchronous data listening. The data buffer is not valid after call of this function.
Parameters
| const TSensrvChannelId aChannelId | Channel Id to be linked to this stop channel data message |
