Inheritance diagram for OSGeo::FDO::Commands::SpatialContext::ICreateSpatialContextImp:
()
Note: The geographic extent of a coordinate system should generally be defined as an envelope (or bounding box). However, any geometry type that falls into the surface geometric types can be used (e.g., polygons). If a non-rectangular area is passed in and the provider supports only a rectangular extent, the provider will compute the minimum box that encloses the given geometry and use that for the extent value.

Public Member Functions | |
System::Void | Execute () |
Executes the CreateSpatialContext command. An exception is thrown if the spatial context already exists, or if the coordinate system or extent type is not supported by the provider. | |
__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::String * | get_Name () |
Gets the name of the context to create as a string. | |
__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. | |
__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 create 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. 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. |
