Detailed Description

Runtime implementation of an AifMapChartDataSource

Constructor & Destructor Documentation

AifMapChartDataSource::AifMapChartDataSource ( bool  UseDefaultCache = true)

Create a new AifMapChartDataSource.

Parameters
UseDefaultCachewhether to use the default caching system. See AIFMapChartLayerCache for more information

Member Function Documentation

void AifMapChartDataSource::AddOverlay ( const std::string &  overlay,
double  resolution 
)

Add an overlay layer to the list of layers to display.

Parameters
overlayThe name of the overlay layer to display. Must correspond to an overlay defined in the AIF file.
resolutionThe resolution of the overlay to display. Must correspond to a resolution of an overlay defined in the AIF file.
double AifMapChartDataSource::GetTargetCellLoadRate ( ) 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 AifMapChartDataSource::InsertOverlay ( int  index,
const std::string &  overlay,
double  resolution 
)

Insert an overlay layer to the list of layers to display at the given position.

Parameters
indexThe index to insert the overlay at, if -1 or greater than the length of the overlay list then inserts at end.
overlayThe name of the overlay layer to display. Must correspond to an overlay defined in the AIF file.
resolutionThe resolution of the overlay to display. Must correspond to a resolution of an overlay defined in the AIF file.
void AifMapChartDataSource::InstallViewManager ( AIFViewManager &  mgr)

Install the view manager. The view manager (after being initialized by the user) will set this class up to add/remove overlays automatically based on the view height

Parameters
mgrManager to install
void AifMapChartDataSource::LoadAifFile ( std::string  filename)

Load an AIF File with the given file name.

Parameters
filenameThe name of the AIF file to load. Can be absolute or relative to the executing directory.
void AifMapChartDataSource::PreCache ( const GeoRect area)

Precache based on geo-rect area. This uses the AIFMapChartCache as the mechanism to precache images

Parameters
areaGeometric rect area to pre-cache
void AifMapChartDataSource::PreCache ( const double  resolution)

Precache based on resolution

Parameters
resolutionResolution to precache at.
void AifMapChartDataSource::RemoveOverlay ( const std::string &  overlay,
double  resolution 
)

Remove an overlay layer from the list of layers to display.

Parameters
overlayThe name of the overlay layer to remove. Must correspond to an overlay defined in the AIF file.
resolutionThe resolution of the overlay to remove. Must correspond to a resolution of an overlay defined in the AIF file.
void AifMapChartDataSource::RemoveOverlay ( const std::string &  overlay)

Remove all overlay layers with the given overlay name.

Parameters
overlayThe name of the set of overlay layers to remove.
void AifMapChartDataSource::RemoveOverlay ( double  resolution)

Remove all overlay layers with the given resolution.

Parameters
resolutionThe resolution of the set of overlay layers to remove.
void AifMapChartDataSource::SetCache ( AIFMapChartLayerCache cache)
virtual

If using custom cache, set it here. Caller responsible for its deallocation if necessary

Parameters
cacheCustom cache to use
void AifMapChartDataSource::SetCacheSize ( const float  memSize)
Parameters
memSizeSet the cached size (megabytes) of images
void AifMapChartDataSource::SetTargetCellLoadRate ( const double  targetCellLoadRate)

Set the target rate in hz at which cells will be loaded

Parameters
targetCellLoadRatetarget rate in hz else 0.0 for no target rate ( i.e. load as quickly as possible )
