TLbsLocRequestQuality Class Reference
| class TLbsLocRequestQuality : public TLbsLocClassTypeBase |
Specifies the desired quality of a location request The TLbsLocRequestQuality is used by the location source observer to specify the desired quality of a location request. An instance of the class is passed to CLbsLocationSourceGpsBase::RequestLocationUpdate().
The parameters in TLbsLocRequestQuality include the desired minimum horizontal and vertical accuracy for the requested location update. It also enables a maximum time to be specified. This is a time limit indicating the maximum time the data source should take to calculate the location.
It is possible to combine both the desired minimum accuracy and the maximum time. In this situation the data source module will respond either when the desired accuracy has been reached or when the time limit has expired. CLbsLocationSourceBase::RequestLocationUpdate() MLbsLocationSourceObserver
Constructor & Destructor Documentation
TLbsLocRequestQuality()
| IMPORT_C | TLbsLocRequestQuality | ( | ) | |
Member Functions Documentation
AssistedClientRequestPresent()
| IMPORT_C TBool | AssistedClientRequestPresent | ( | ) | const |
Is the request, at least in part, coming from the client API? And is the client asking that assistance data should be retrieved?
MaxFixTime()
Maximum time a data source should spend calculating the current location.
SetMaxFixTime
MinHorizontalAccuracy()
| IMPORT_C TReal32 | MinHorizontalAccuracy | ( | ) | const |
Desired minimum horizontal accuracy for a location update. SetMaxFixTime
MinVerticalAccuracy()
| IMPORT_C TReal32 | MinVerticalAccuracy | ( | ) | const |
Desired minimum vertical accuracy for a location update. SetMaxFixTime
SetAssistedClientRequestPresent(TBool)
| IMPORT_C void | SetAssistedClientRequestPresent | ( | TBool | aAssistedClientRequestPresent | ) | |
Sets the flag to true if there is an outstanding request from the client API that is part of the current request and if this request (coming from the client) is an assisted request (non-autonomous)
Parameters
| TBool aAssistedClientRequestPresent | |
SetMaxFixTime(TTimeIntervalMicroSeconds)
Maximum time a data source should spend calculating the current location.
When used in conjunction with SetMinHorizontalAccuracy and/or SetMinVerticalAccuracy the data source will produce an update either when the desired accuracy has be met or when the time limit is reached.
SetMaxFixTime
Parameters
| TTimeIntervalMicroSeconds aTime | specifies the maximum time that the data source should spend calculating the current location. |
SetMinHorizontalAccuracy(TReal32)
| IMPORT_C void | SetMinHorizontalAccuracy | ( | TReal32 | aAccuracy | ) | |
Desired minimum horizontal accuracy for a location update.
When used in conjunction with SetMaxFixTime the data source will produce an update either when the desired accuracy is met or when the time limit is reached. SetMaxFixTime
Parameters
| TReal32 aAccuracy | specifies the desired minimum horizontal accuracy (in metres) for a location update produced by the data source. |
SetMinVerticalAccuracy(TReal32)
| IMPORT_C void | SetMinVerticalAccuracy | ( | TReal32 | aAccuracy | ) | |
Desired minimum vertical accuracy for a location update. When used in conjunction with SetMaxFixTime the data source will produce an update either when the desired accuracy is met or when the time limit is reached. SetMaxFixTime
Parameters
| TReal32 aAccuracy | specifies the desired minimum vertical accuracy (in metres) for a location update produced by the data source. |
