Detailed Description

The vtStructureArray class contains a list of Built Structures (vtStructure objects). It can be loaded and saved to VTST files with the ReadXML and WriteXML methods.

Member Function Documentation

int vtStructureArray::DeleteSelected (   )

Delete any structures which are selected. Returns: the number that were deleted.

bool vtStructureArray::FindClosestBuilding (  const DPoint2 &  point, double  epsilon, int &  structure, double &  closest )

Find the building which is closest to the given point, if it is within 'epsilon' distance. The structure index and distance are returned by reference. Returns: True if a building was found.

bool vtStructureArray::FindClosestBuildingCenter (  const DPoint2 &  point, double  epsilon, int &  building, double &  closest )

Find the building center closest to the given point, if it is within 'epsilon' distance. The building index, and distance from the given point are returned by reference. Returns: True if a building was found.

bool vtStructureArray::FindClosestBuildingCorner (  const DPoint2 &  point, double  epsilon, int &  building, int &  corner, double &  closest )

Find the building corner closest to the given point, if it is within 'epsilon' distance. The building index, corner index, and distance from the given point are all returned by reference. Returns: True if a building was found.

bool vtStructureArray::FindClosestStructure (  const DPoint2 &  point, double  epsilon, int &  structure, double &  closest, float  fMaxInstRadius = 1E9f, float  fLinearWidthBuffer = 0.0f )

Find the structure which is closest to the given point, if it is within 'epsilon' distance. The structure index and distance are returned by reference. Returns: True if a building was found.

int vtStructureArray::GetFirstSelected (   )

Return the index of the first selected structure, or -1 if no structure is selected.

bool vtStructureArray::ReadSHP (  const char *  pathname, StructImportOptions &  opt, bool   progress_callback(int) = NULL )

Import structure information from a Shapefile. Parameters: pathname  A resolvable filename of a Shapefile (.shp) opt  Options which specify how to import structures from the file. progress_callback  If supplied, this function will be called back with a value of 0 to 100 as the operation progresses. Returns: True if successful.
