FeatureTable Class | ArcGIS Maps SDK for Qt

A table of features that typically represents real-world objects such as fire hydrants, roads, and forests. More...

Destructor.

Adds a feature to the table.

• feature - The feature.

Adding a feature that contains a Geometry causes the geometry to become simplified. This may change a single part geometry to a multipart geometry, or round off X, Y, Z, and M coordinate values that are above the resolution set by the SpatialReference.

Adding a feature to a GeodatabaseFeatureTable in a stand-alone mobile geodatabase created with ArcGIS Pro is not supported when the table participates in a controller dataset, such as a utility network or parcel fabric. Use canAdd to determine if this operation is allowed.

This method returns a QFuture for the asynchronous operation. Use future.then() to continue processing when the operation completes. Use future.onFailed() to handle exceptions of type ErrorException.

See Working with QFuture for further details.

This function was introduced in Esri::ArcGISRuntime 200.2.

See also FeatureServiceSessionType.

Adds a collection of features to the table.

• features - A QList of Feature. Contents of the QList are copied.

This method returns a QFuture for the asynchronous operation. Use future.then() to continue processing when the operation completes. Use future.onFailed() to handle exceptions of type ErrorException.

Returns true if you can add new features to the table.

The result of this method accounts for the table's attachment and geometry capabilites, and ownership-based access control.

Although this method may state that the table allows new features to be added, the application may not be licensed to permit this. For example, a user cannot add features to a secured feature table if the application is licensed at the Lite level (LicenseLevel::Lite).

Returns true if the provided feature can be deleted from the table.

• feature - The feature.

The result of this method accounts for the table's attachment and geometry capabilites, and ownership-based access control.

Although this method may state that the table allows the feature to be deleted, the application may not be licensed to permit this. For example, a user cannot delete features from a secured feature table if the application is licensed at the Lite level (LicenseLevel::Lite).

Returns true if the feature table allows editing a feature's geometry.

The result of this method accounts for the table's ownership-based access control.

Although this method may state that the table allows geometry fields to be edited, the application may not be licensed to permit this. For example, a user cannot update geometry in a secured feature table if the application is licensed at the Lite level (LicenseLevel::Lite).

Returns true if the provided feature can be updated in the table.

• feature - The feature.

The result of this method accounts for the table's attachment and geometry capabilites, and ownership-based access control.

Reimplements: Loadable::cancelLoad().

Cancels loading the metadata for the object.

Creates and returns a new, empty feature with an optional parent.

The new feature is only available in memory at this point. Execute addFeatureAsync(Esri::ArcGISRuntime::Feature*) to commit the new Feature to the table.

Returns a new feature with the provided attribute values and, optionally, geometry.

• attributes - The attributes.
• geometry - The geometry.
• parent - The parent object.

The new feature is only available in memory at this point. Execute addFeatureAsync(Esri::ArcGISRuntime::Feature*) to commit the new Feature to the table.

Note: The keys of the attributes dictionary will be treated as case-insensitive.

See Internal data structures with case-insensitive string keys for further details.

Deletes a feature from the table.

• feature - The feature.

Deleting a feature from a GeodatabaseFeatureTable in a stand-alone mobile geodatabase created with ArcGIS Pro is not supported when the table participates in a controller dataset, such as a utility network or parcel fabric. Use canDelete(Esri::ArcGISRuntime::Feature*) to determine if this operation is allowed.

This method returns a QFuture for the asynchronous operation. Use future.then() to continue processing when the operation completes. Use future.onFailed() to handle exceptions of type ErrorException.

Returns a user-friendly name that can be displayed in the UI (for example, in a Table of Contents).

If the table is displayed with a FeatureLayer, the FeatureTable::displayName is used as the FeatureLayer::name.

The default value is tableName.

This function was introduced in Esri::ArcGISRuntime 100.3.

See also setDisplayName().

Signal emitted when this object is done loading.

• loadError - Details about any error that may have occurred.

Note: If there is a load error it will also be emitted on the errorOccurred signal.

See also Loadable and Object.

Returns the geographic extent of features within the table.

This is calculated differently for specific types and modes of feature tables:

• ServiceFeatureTable. If the feature request mode is FeatureRequestMode::ManualCache the service feature table will return the extent of the features which have been cached. All other modes will return the extent of the layer/table defined by the service (from ArcGISFeatureLayerInfo::extent). This can be used to determine the extent within which data can be edited.

• GeodatabaseFeatureTable. This returns the extent of the features which have been cached. This extent can grow as features are added or edited, but not shrink.

Returns the type of feature table.

Returns a Field object describing the field corresponding to the provided fieldName.

Returns a list of Field objects representing the fields of the feature table.

Returns the type of geometry of the features stored in this table.

If hasGeometry is false, then the geometry type is GeometryType::Unknown.

Returns true if the dataset contains a geometry field.

If true, the dataset contains geographic features. If false, the dataset contains non-spatial records, similar to a database table.

Returns true if the feature table supports geometries with M values, false otherwise.

This function was introduced in Esri::ArcGISRuntime 100.2.

Returns true if the feature table supports geometries with Z values, false otherwise.

This function was introduced in Esri::ArcGISRuntime 100.2.

Returns true if this feature table is editable, false otherwise.

Underlying file permissions (for subclasses such as ShapefileFeatureTable and GeodatabaseFeatureTable) can be changed while the feature table is open. In these cases the value of this property may not be accurate.

See also ArcGISFeatureTable.

Reimplements: PopupSource::isPopupEnabled() const.

Returns a flag indicating whether the PopupDefinition defined on the PopupSource is enable / disable.

This function was introduced in Esri::ArcGISRuntime 100.1.

Returns the layer that displays this table, if any.

The Layer type depends on how the feature table is created. For example, a Layer will be an AnnotationLayer if the FeatureTable is created from a table that supports annotation. See Layer for more information about the supported layer types.

The layer will be nullptr if the feature table does not contain spatial features (where hasGeometry is false).

This function was introduced in Esri::ArcGISRuntime 100.7.

Reimplements: Loadable::load().

Loads the metadata for the object asynchronously.

Reimplements: Loadable::loadError() const.

Returns the load error.

See also Error.

Reimplements: Loadable::loadStatus() const.

Returns the load status.

See also LoadStatus.

Signal emitted when the load status changes for this object.

• loadStatus - The LoadStatus.

See also Loadable.

Returns the number of features in the table.

If all the features are stored in the local table, for example with a GeodatabaseFeatureTable or a ShapefileFeatureTable, then the numberOfFeatures will return the full number of features.

If the table is created from a service, for example, ServiceFeatureTable or WfsFeatureTable, the numberOfFeatures will only return the number of features in the local table cache. You need to populate the local table cache to return a value for numberOfFeatures. Do this by rendering the features in a Map or Scene with a FeatureLayer, or by querying the feature table. Consider the feature table's FeatureRequestMode in both cases. See ServiceFeatureTable or WfsFeatureTable for more information. If you want to return the full number of features in the service, execute queryFeatureCountAsync(const Esri::ArcGISRuntime::QueryParameters&) and pass "1=1" to the QueryParameters::whereClause.

Reimplements: PopupSource::popupDefinition() const.

Returns the pop-up definition.

The PopupDefinition associated with the popup source. A nullptr if an error occurs or if the popup source is not associated with a pop-up definition.

This function was introduced in Esri::ArcGISRuntime 100.1.

See also setPopupDefinition() and PopupSource.

Returns the popup definition for the given feature in the feature table.

• feature - The feature to retrieve the popup definition for.
