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 NAMESPACE_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. | |
| __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 (NAMESPACE_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. | |
Variables | |
| BEGIN_NAMESPACE_OSGEO_FDO_COMMANDS_SPATIALCONTEXT public __gc __interface | ICreateSpatialContext |
| The FdoICreateSpatialContext interface defines the CreateSpatialContext command, which creates a new spatial context. Input to the command includes the name, description, coordinate system, extent type, and extent for the new context. Command execution will fail if the context already exists, or if the coordinate system or extent type is not supported by the provider. | |
