An internal method to add a selection criteria choice to the current set of criteria.
An internal method to add a selection criteria choice to the current set of criteria.
| Parameters | |
|---|---|
| aField | is a position quality metric, eg. horizontal accuracy |
| aOrder | is the priority for the given quality metric. |
| IMPORT_C void | ClearSelectionOrder | ( | ) |
Clear all values including defaults. This is useful if the application wishes to specify its own priorities.
Not generally called by client applications. It retrieves a particular selection parameter.
| Parameters | |
|---|---|
| aIndex | the index of a selection parameter |
| aField | is set, upon successful completion, to the field ID at index aIndex. |
| aOrder | is set, upon successful completion, to the priority of the field at index aIndex. |
| IMPORT_C TUint | NumSelectionItems | ( | ) | const |
Not generally called by client applications. It retrieves the number of selection parameters.
| IMPORT_C void | ResetSelectionOrder | ( | ) |
Used to restore the default selection ordering.
