const char * |
customScaleString, |
|
|
const char * |

|
) |
| |
Uses the currentScaleString value to derive a new map layer from the existing layer identified by currentScaleString.
- Parameters
-
currentScaleString | should be the string of an existing layer e.g. "1:5M". The valid of currentScaleString values are: string - layer name "1:5M" - GNC "1:2M" - JNC "1:1M" - ONC "1:500K" - TPC "1:250K" - JOG "1:100K" - TLM "1:50K" - TLM |
customScaleString | the string to be added to the above list of strings e.g."Custom1:5M". |
customExtension | the two character non-numeric file extension that can be used to find files for this layer. |
void disti::CADRGMapChartDataSource::CalcAvailableCoverage |
( |
| ) |
|
Updates the coverage area that is returned by GetAvailableCoverage. This is called automatically when something causes the coverage area to change. This method is slow, users of the class should not need to call it directly.
bool disti::CADRGMapChartDataSource::GetAvailableCoverage |
( |
GeoRect * |
dest | ) |
|
|
virtual |
Sets a GeoRect to describe the area containing all areas covered by this MapDataSource. This area may change as different databases are loaded. Calling this method may be slow. Pointer to a GeoRect to recieve the coverage.
- Returns
- true on success (dest contains the coverage description) or false if there was an error (dest is undefined)
Implements disti::GlsMapChartDataSource.

( |
GlsMapView * |
view, |
|
|
GlsMapChart * |
chart |
|
) |
| const |
|
virtual |
Returns the cell layer ('zoom level') that best matches the given area
- Parameters
-
- Returns
- The recommended layer to use
- Note
- Data sources that do not support layers should always return 0.
Reimplemented from disti::GlsMapChartDataSource.
unsigned long disti::CADRGMapChartDataSource::GetCADRGLayer |
( |
void |
| ) |
|
|
inline |
Get the currently set layer for CADRG data.
- Returns

) |
| |
|
virtual |
Get the list of the available cells in a given coverage area The caller will AddRef() any of the cells that it will be holding a reference to
- Parameters
-
coverage | GeoRect describing the requested area |
layerID | Which layer to return MapCells from |
viewLogicalHeight | The height of the view in logical units |
viewGeoHeight | The height of the view in geographic units |
viewList | Pointer MapChartCellList to recieve the list of available cells |
Implements disti::GlsMapChartDataSource.
unsigned long disti::CADRGMapChartDataSource::GetCIBLayer |
( |
void |
| ) |
|
|
inline |
Get the currently set layer for CIB data.
- Returns
- The currently set layer for CIB data.
unsigned int disti::CADRGMapChartDataSource::GetLayerCacheCount |
( |
void |
| ) |
const |
Get the count of the layer cache
- Returns
- max number of layers to cache ( 0u if layer caching is disabled )
double disti::CADRGMapChartDataSource::GetTargetCellLoadRate |
( |
void |
| ) |
const |
Get the target rate in hz at which cells will be loaded
- Returns
- target rate in hz else 0.0 for no target rate ( i.e. load as quickly as possible )
void disti::CADRGMapChartDataSource::SetCADRGLayer |
