# OSGeo::FDO::Commands::SpatialContext

## Classes
interface | OSGeo::FDO::Commands::SpatialContext::IActivateSpatialContext
| The IActivateSpatialContext interface defines the ActivateSpatialContext command, which activates a specified spatial context. Input to the command is the name of the context to activate. More...
class | OSGeo::FDO::Commands::SpatialContext::IActivateSpatialContextImp
| The IActivateSpatialContextImp class is a concrete implementation of IActivateSpatialContext. The IActivateSpatialContext interface defines the ActivateSpatialContext command, which activates a specified spatial context. Input to the command is the name of the context to activate. More...
interface | OSGeo::FDO::Commands::SpatialContext::ICreateSpatialContext
| The ICreateSpatialContext 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. More...
class | OSGeo::FDO::Commands::SpatialContext::ICreateSpatialContextImp
| The ICreateSpatialContextImp class is a concrete implementation of ICreateSpatialContext. The ICreateSpatialContext 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. More...
interface | OSGeo::FDO::Commands::SpatialContext::IDestroySpatialContext
| The IDestroySpatialContext interface defines the DestroySpatialContext command, which destroys an existing spatial context. Input to the command is the name of the context to destroy. Destroying a spatial context destroys all data stored in that context. More...
class | OSGeo::FDO::Commands::SpatialContext::IDestroySpatialContextImp
| The IDestroySpatialContextImp class is a concrete implementation of IDestroySpatialContext. The IDestroySpatialContext interface defines the DestroySpatialContext command, which destroys an existing spatial context. Input to the command is the name of the context to destroy. Destroying a spatial context destroys all data stored in that context. More...
interface | OSGeo::FDO::Commands::SpatialContext::IGetSpatialContexts
| IGetSpatialContexts interface defines the GetSpatialContexts command, which enumerates the existing spatial contexts. More...
class | OSGeo::FDO::Commands::SpatialContext::IGetSpatialContextsImp
| The IGetSpatialContextsImp class is a concrete implementation of IGetSpatialContexts. The IGetSpatialContexts interface defines the GetSpatialContexts command, which enumerates the existing spatial contexts. More...
interface | OSGeo::FDO::Commands::SpatialContext::ISpatialContextReader
| ISpatialContextReader interface provides forward-only, read-only functionality for enumerating spatial contexts. A reference to an ISpatialContextReader is returned from the GetSpatialContexts command. The initial position of the ISpatialContextReader interface is prior to the first item. Thus, you must call ReadNext to begin accessing any data. More...

## Enumerations
enum | SpatialContextExtentType { SpatialContextExtentType_Static = FdoSpatialContextExtentType_Static, SpatialContextExtentType_Dynamic = FdoSpatialContextExtentType_Dynamic }
| The SpatialContextExtentType enumeration defines how the extent of a context should be handled by the provider. More...
