FDO_API void FdoXmlSpatialContextWriter::SetXYTolerance const double  value  ) 
 

Sets the tolerance value to use for X/Y ordinates. 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.

Parameters:
value Input the tolerance
Returns:
Returns nothing
