FdoXmlSpatialContextWriter Class Reference

FdoXmlSpatialContextWriter writes Spatial Contexts to an XML document. This is done by calling the various setter functions to set the spatial context attributes and then calling WriteSpatialContext() to write the spatial context using the current attributes. More...

Public Member Functions

FDO_API FdoStringGetCoordinateSystem ()
 Gets the name of the coordinate system of the context to create.
FDO_API FdoStringGetCoordinateSystemWkt ()
 Gets the coordinate system of the context to create as a string in OpenGIS SRS WKT format.
FDO_API FdoStringGetDescription ()
 Gets the description of the context to create as a string.
FDO_API FdoByteArrayGetExtent ()
 Gets the extent of the context to create as a byte array in FGF format. If the extent type is dynamic, any value specified via this function is ignored.
FDO_API FdoSpatialContextExtentType GetExtentType ()
 Gets the desired extent type of the context to create, either static or dynamic.
FDO_API FdoStringGetName ()
 Gets the name of the context to create as a string.
FDO_API const double GetXYTolerance ()
 Gets 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.
FDO_API const double GetZTolerance ()
 Gets the tolerance value to use for Z 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.
FDO_API void SetCoordinateSystem (FdoString *value)
 Gets the name of the coordinate system of the context to create.
FDO_API void SetCoordinateSystemWkt (FdoString *value)
 Sets the coordinate system of the context to create as a string in OpenGIS SRS WKT format.
FDO_API void SetDescription (FdoString *value)
 Sets the description of the context to create as a string.
FDO_API void SetExtent (FdoByteArray *value)
 Sets the extent of the context to create as a byte array in FGF format. If the extent type is dynamic this is optional and any value specified is ignored.
FDO_API void SetExtentType (FdoSpatialContextExtentType value)
 Sets the desired extent type of the context to create, either static or dynamic.
FDO_API void SetName (FdoString *value)
 Sets the name of the context to create as a string.
FDO_API void 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.
FDO_API void SetZTolerance (const double value)
 Sets the tolerance value to use for Z 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.
FDO_API void WriteSpatialContext ()
 Writes the current Spatial Context to the XML document.
