List of all members.

Public Member Functions
void	Add (CREFSTRING layer, CREFSTRING className, CREFSTRING id)
	Adds the given feature (represented by its base64 encoded id) to the selection set.
void	AddFeatureIdDouble (MgLayerBase *layer, CREFSTRING className, double identifier)
	Add a single selection to the set where the identity property is a double.
void	AddFeatureIdInt16 (MgLayerBase *layer, CREFSTRING className, INT16 identifier)
	Add a single selection to the set where the identity property is a 16-bit integer.
void	AddFeatureIdInt32 (MgLayerBase *layer, CREFSTRING className, INT32 identifier)
	Add a single selection to the set where the identity property is a 32-bit integer.
void	AddFeatureIdInt64 (MgLayerBase *layer, CREFSTRING className, INT64 identifier)
	Add a single selection to the set where the identity property is a 64-bit integer.
void	AddFeatureIds (MgLayerBase *layer, CREFSTRING className, MgPropertyCollection *identityProperties)
	Add a single selection to the set based on a collection of identity properties.
void	AddFeatureIdString (MgLayerBase *layer, CREFSTRING className, CREFSTRING identifier)
	Add a single selection to the set where the identity property is a string.
void	AddFeatures (MgLayerBase *layer, MgFeatureReader *features, INT32 nFeatures)
	Add nFeatures to selection set from the FeatureReader. Specify nFeatures = 0 for all features in reader. Internal identity mapping for layer dictates the properties used.
bool	Contains (MgLayerBase *layer, CREFSTRING className)
	Does a particular layer and class have selections.
void	FromXml (CREFSTRING xmlSelectionString)
	Read selection from XML document. Previous selection is cleared.
STRING	GenerateFilter (MgLayerBase *layer, CREFSTRING className)
	Generates an Fdo filter text for the selections of the specified layer and class.
MgStringCollection *	GenerateFilters (MgLayerBase *layer, CREFSTRING className, INT32 selectionSize)
	Generates a collection of FDO filter strings for the selections of the specified layer and class.
STRING	GetClass (CREFSTRING layer)
	Returns the class name for the layer.
MgStringCollection *	GetClasses (CREFSTRING layer)
	Returns list of selected classes for a layer.
MgEnvelope *	GetExtents (MgFeatureService *featureService)
	Gets the extents of the selection set.
MgReadOnlyLayerCollection *	GetLayers ()
	Returns list of selected layers.
STRING	GetResourceName (CREFSTRING sessionId, CREFSTRING mapName)
	Builds a resource name based on the map name amd the session id.
virtual MgFeatureReader *	GetSelectedFeatures (MgLayerBase *layer, CREFSTRING className, bool mappedOnly)
	Returns the selected feature data for the specified feature class.
virtual MgFeatureReader *	GetSelectedFeatures (MgLayerBase *layer, CREFSTRING className, MgStringCollection *propertyNames)
INT32	GetSelectedFeaturesCount (MgLayerBase *layer, CREFSTRING className)
	Returns the number of selected features.
	MgSelectionBase (MgMapBase *map)
	Initialize selection generation from a map.
	MgSelectionBase (MgMapBase *map, CREFSTRING xmlSelectionString)
	Initialize selection from a map and xml selection.
virtual void	Open (MgResourceService *resourceService, CREFSTRING mapName)
	Loads the map object from a session repository.
virtual void	Save (MgResourceService *resourceService, CREFSTRING mapName)
	Save the map object to a session repository.
STRING	ToXml ()
