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...
