Functions |
| System::Void | Execute () |
| | Executes the GetSpatialContexts command returning an ISpatialContextReader.
|
| __property System::String * | get_CoordinateSystem () |
| | Gets the coordinate system of the context to create as a string in OpenGIS SRS WKT format.
|
| __property System::String * | get_CoordinateSystemWkt () |
| | Gets the coordinate system definition in OGC SRS WKT format for the spatial context currently being created. If the result is an empty string, the coordinate system WKT description has not been set.
|
| __property System::String * | get_Description () |
| | Gets the description of the context to create as a string.
|
| __property System::Byte | get_Extent ()[] |
| | 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.
|
| __property OSGeo::FDO::Commands::SpatialContext::SpatialContextExtentType | get_ExtentType () |
| | Gets the desired extent type of the context to create, either static or dynamic.
|
| __property System::Boolean | get_UpdateExisting () |
| | Gets a Boolean flag that indicates how the CreateSpatialContext command should behave if the spatial context already exists. If update existing is true and a spatial context with the specified name already exists then it will be updated. If update existing is false and a spatial context with the specified name already exists, command execution will fail.
|
| __property System::Double | get_XYTolerance () |
| | 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.
|
| __property System::Double | get_ZTolerance () |
| | 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.
|
| System::String * | GetCoordinateSystem () |
| | Gets the name of the coordinate system of the spatial context currently being read. If the result is a null or empty string, the coordinate system is unknown to the spatial context.
|
| System::String * | GetCoordinateSystemWkt () |
| | Gets the name of the coordinate system in OpenGIS SRS WKT format of the spatial context currently being read. If the result is an empty string, the coordinate system WKT description is not available.
|
| System::String * | GetDescription () |
| | Gets the description of the spatial context currently being read.
|
| System::Byte | GetExtent ()[] |
| | Gets the extent of the spatial context currently being read as a byte array in FGF format.
|
| OSGeo::FDO::Commands::SpatialContext::SpatialContextExtentType | GetExtentType () |
| | Gets the extent type of the spatial context currently being read.
|
| System::Double | GetXYTolerance () |
| | 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.
|
| System::Double | GetZTolerance () |
| | Gets the tolerance value for Z ordinates of the spatial context currently being read. Tolerances are used in some geometric tests, mostly for equality between coordinates. This occurs a 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.
|
| System::Boolean | IsActive () |
| | Returns true if the spatial context currently being read is the active spatial context.
|
| System::Boolean | ReadNext () |
| | Advances the reader to the next item. The default position of the reader is prior to the first item. Thus, you must call ReadNext to begin accessing any data.
|
| __property System::Void | set_ActiveOnly (System::Boolean value) |
| | Sets a Boolean flag that indicates if the GetSpatialContexts command will return only the active spatial context or all spatial contexts. The default value of this flag is false, return all spatial contexts.
|
| __property System::Void | set_CoordinateSystem (System::String *value) |
| | Sets the coordinate system of the context to create as a string in OpenGIS SRS WKT format.
|
| __property System::Void | set_CoordinateSystemWkt (System::String *value) |
| | Sets the coordinate system definition in OGC SRS WKT format for the spatial context currently being created.
|
| __property System::Void | set_Description (System::String *value) |
| | Sets the description of the context to create as a string.
|
| __property System::Void | set_Extent (System::Byte buffer[]) |
| | 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.
|
| __property System::Void | set_ExtentType (OSGeo::FDO::Commands::SpatialContext::SpatialContextExtentType value) |
| | Sets the desired extent type of the context to create, either static or dynamic.
|
| __property System::Void | set_Name (System::String *value) |
| | Sets the name of the context to destroy as a string.
|
| __property System::Void | set_UpdateExisting (System::Boolean value) |
| | Sets a Boolean flag that indicates how the CreateSpatialContext command should behave if the spatial context already exists. If update existing is true and a spatial context with the specified name already exists then it will be updated. If update existing is false and a spatial context with the specified name already exists, command execution will fail.
|
| __property System::Void | set_XYTolerance (System::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.
|
| __property System::Void | set_ZTolerance (System::Double value) |
| | Sets the tolerance value to use for Z ordinates. Tolerances are used in some geometric tests, mostly for equality between coordinates.
