virtual FDO_API const double FdoISpatialContextReader::GetXYTolerance | ( |  | ) | `[pure virtual]`
Gets the tolerance value for XY ordinates of the spatial context currently being read. Tolerances are used in some geometric tests, mostly for equality between coordinates. This occurs frequently in spatial queries, especially with "on boundary" or "just touching" conditions. It is also an objective amount that can be used when formulating step distances for parametric curve interpolation. Returns: Returns the tolerance Implemented in FdoXmlSpatialContextReader.
