Detailed Description
A map database that holds map objects in memory. This class is used to hold highlighted objects and other temporary objects like pushpins, or any other map objects not stored in the main database.
Constructor & Destructor Documentation
| CT_EXPORT CMemoryMapDataBase::CMemoryMapDataBase | ( | ) |
Create an empty memory-resident map database.
Member Function Documentation
Append a new layer with no attributes to a memory-resident map database, specifying the layer by name. Add an attribute called Type, or RoadType if the layer name is 'road'.
| CT_EXPORT TResult CMemoryMapDataBase::AppendLineObject | ( | int32 | aLayerIndex, |
| const MPath & | aPath, | ||
| const MString * | aLabel, | ||
| uint32 | aId, | ||
| const TMapAttribute * | aAttribute = NULL, |
||
| int32 | aAttributes = 0 |
||
| ) |
Append a line object to a memory-resident map database,
| CT_EXPORT TResult CMemoryMapDataBase::AppendObject | ( | int32 | aLayerIndex, |
| const CMapObject & | aObject, | ||
| int32 | aCircleRadius | ||
| ) |
Append an arbitrary map object to a memory-resident map database. If the object is a point, and aCircleRadius is greater than zero, convert it to a circle of the specified radius.
| CT_EXPORT TResult CMemoryMapDataBase::AppendPointObject | ( | int32 | aLayerIndex, |
| const TPoint & | aPoint, | ||
| const MString * | aLabel, | ||
| uint32 | aId, | ||
| const TMapAttribute * | aAttribute = NULL, |
||
| int32 | aAttributes = 0 |
||
| ) |
Append a point object to a memory-resident map database,
| CT_EXPORT TResult CMemoryMapDataBase::AppendPolygonObject | ( | int32 | aLayerIndex, |
| const MPath & | aPath, | ||
| const MString * | aLabel, | ||
| uint32 | aId, | ||
| const TMapAttribute * | aAttribute = NULL, |
||
| int32 | aAttributes = 0 |
||
| ) |
Append a polygon object to a memory-resident map database,
| CT_EXPORT void CMemoryMapDataBase::Clear | ( | ) |
Delete all the map objects in the database and set the extent to nothing. Do not delete or change the layers or any other data.
| CT_EXPORT int32 CMemoryMapDataBase::Delete | ( | uint32 | aStartId, |
| uint32 | aEndId | ||
| ) |
Delete all map objects with IDs in the range aStartId and aEndId inclusive. Return the number of objects deleted.
| CT_EXPORT int32 CMemoryMapDataBase::DeleteAllObjectsInLayer | ( | const MString & | aLayerName | ) |
Delete all map objects in the specified layer.
| const CBasicMapObject& CartoType::CMemoryMapDataBase::MapObject | ( | int | aIndex | ) | const [inline] |
Return a const reference to a map object in the database, selecting it by index.
| CBasicMapObject& CartoType::CMemoryMapDataBase::MapObject | ( | int | aIndex | ) | [inline] |
Return a non-const reference to a map object in the database, selecting it by index.
| int32 CartoType::CMemoryMapDataBase::MapObjects | ( | ) | const [inline] |
Return the number of map objects in the database.
| CT_EXPORT void CMemoryMapDataBase::RecalculateExtent | ( | ) |
Recalculate the extent: the bounding rectangle of all the objects in the database. For use if objects in the database have been modified directly.
