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.
|
| 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, MgStringCollection *propertyNames) |
| virtual MgFeatureReader * | GetSelectedFeatures (MgLayerBase *layer, CREFSTRING className, bool mappedOnly) |
| | Returns the selected feature data for the specified feature class.
|
| INT32 | GetSelectedFeaturesCount (MgLayerBase *layer, CREFSTRING className) |
| | Returns the number of selected features.
|
| | MgSelectionBase (MgMapBase *map, CREFSTRING xmlSelectionString) |
| | Initialize selection from a map and xml selection.
|
| | MgSelectionBase (MgMapBase *map) |
| | Initialize selection generation from a map.
|
| 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 () |
| | Write selection as XML document. This document will typically be passed back to a viewer to select the desired features.
