DynamicEntityLayer Class | ArcGIS Maps SDK for Qt

A Layer that displays dynamic entity observations from real-time services. More...

Member Function Documentation [explicit] DynamicEntityLayer::DynamicEntityLayer(Esri::ArcGISRuntime::DynamicEntityDataSource *dataSource, QObject *parent = nullptr)

Creates a new dynamic entity layer from a DynamicEntityDataSource.

dataSource - A DynamicEntityDataSource data source.
parent - The optional parent QObject.

[explicit, since Esri::ArcGISRuntime 200.6] DynamicEntityLayer::DynamicEntityLayer(Esri::ArcGISRuntime::PortalItem *portalItem, QObject *parent = nullptr)

Creates a new dynamic entity layer object from a stream service portal item.

portalItem - A stream service PortalItem.
parent - The optional parent QObject.

The item's type must be PortalItemType::Feed or PortalItemType::StreamService.

This function was introduced in Esri::ArcGISRuntime 200.6.

See also PortalItem, PortalItem::PortalItem(const QUrl&, QObject*), and Layer::item.

[override virtual noexcept] DynamicEntityLayer::~DynamicEntityLayer()

Destructor.

void DynamicEntityLayer::clearSelection()

Clears all selected dynamic entity observations.

Use this method to clear the list of selected DynamicEntity and DynamicEntityObservation objects and clear the visible selection halos from the map or scene view.

Esri::ArcGISRuntime::DynamicEntityDataSource *DynamicEntityLayer::dataSource() const

Returns the dynamic entity data source.

bool DynamicEntityLayer::isLabelsEnabled() const

Returns true if labels should be displayed, false otherwise.

Dynamic entity layer supports labeling only on the latest observation of a track.

[override virtual] bool DynamicEntityLayer::isPopupEnabled() const

Reimplements: PopupSource::isPopupEnabled() const.

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

Esri::ArcGISRuntime::LabelDefinitionListModel *DynamicEntityLayer::labelDefinitions() const

Returns the collection of LabelDefinition objects for this layer.

Dynamic entity layer supports labeling only on the latest observation of a track.

[override virtual] Esri::ArcGISRuntime::PopupDefinition *DynamicEntityLayer::popupDefinition() const

Reimplements: PopupSource::popupDefinition() const.

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

See also setPopupDefinition().

Esri::ArcGISRuntime::Renderer *DynamicEntityLayer::renderer() const

Returns the Renderer used to display the latest observation of dynamic entities.

See also setRenderer().

Esri::ArcGISRuntime::LayerSceneProperties DynamicEntityLayer::sceneProperties() const

Returns the scene properties for the dynamic entity layer.

See also setSceneProperties().

void DynamicEntityLayer::selectDynamicEntities(const QList<Esri::ArcGISRuntime::DynamicEntity *> &dynamicEntities)

Selects the specified dynamic entities.

dynamicEntities - The dynamic entities to select.

Selecting a DynamicEntity does the following:

adds the dynamic entity to the current list of selected dynamic entities.
adds a visual selection halo around the latest observation of the dynamic entity. The selection halo is always placed on the latest observation of the dynamic entity, so the selection halo moves as new observations are received for the dynamic entity.

void DynamicEntityLayer::selectDynamicEntity(Esri::ArcGISRuntime::DynamicEntity *dynamicEntity)

Selects the given dynamic entity and adds it to the current list of selected dynamic entities.

dynamicEntity - The dynamic entity to select.

Selecting a DynamicEntity does the following:

adds the dynamic entity to the current list of selected dynamic entities.
adds a visual selection halo around the latest observation of the dynamic entity. The selection halo is always placed on the latest observation of the dynamic entity, so the selection halo moves as new observations are received for the dynamic entity.

void DynamicEntityLayer::selectDynamicEntityObservation(Esri::ArcGISRuntime::DynamicEntityObservation *dynamicEntityObservation)

Selects the given dynamic entity observation and adds it to the current list of selected observations.

dynamicEntityObservation - The dynamic entity observation to select.

Selecting a DynamicEntityObservation does the following:

adds the DynamicEntityObservation to the current list of selected dynamic entity observations.
adds a visual selection halo around the static DynamicEntityObservation.

Use selectDynamicEntity(Esri::ArcGISRuntime::DynamicEntity*) to achieve dynamic selection of the latest observation in a track.

void DynamicEntityLayer::selectDynamicEntityObservations(const QList<Esri::ArcGISRuntime::DynamicEntityObservation *> &dynamicEntityObservations)

Selects the given dynamic entity observations and adds them to the current list of selected observations.

dynamicEntityObservations - The dynamic entity observations to select.

Selecting a DynamicEntityObservation does the following:

adds the DynamicEntityObservation to the current list of selected dynamic entity observations.
adds a visual selection halo around the static DynamicEntityObservation.

Use selectDynamicEntity(Esri::ArcGISRuntime::DynamicEntity*) to achieve dynamic selection of the latest observation in a track.

QList<Esri::ArcGISRuntime::DynamicEntity *> DynamicEntityLayer::selectedDynamicEntities() const

Returns all selected dynamic entities.

QList<Esri::ArcGISRuntime::DynamicEntityObservation *> DynamicEntityLayer::selectedDynamicEntityObservations() const

Returns all selected dynamic entity observations.

void DynamicEntityLayer::setLabelsEnabled(bool labelsEnabled)

Sets the labelsEnabled to labelsEnabled.

See also isLabelsEnabled.

[override virtual] void DynamicEntityLayer::setPopupDefinition(Esri::ArcGISRuntime::PopupDefinition *popupDefinition)

Reimplements: PopupSource::setPopupDefinition(Esri::ArcGISRuntime::PopupDefinition *popupDefinition).

Sets the popupDefinition to popupDefinition.

See also popupDefinition.

[override virtual] void DynamicEntityLayer::setPopupEnabled(bool popupEnabled)

Reimplements: PopupSource::setPopupEnabled(bool popupEnabled).

Sets the popupEnabled to popupEnabled.

See also isPopupEnabled.

void DynamicEntityLayer::setRenderer(Esri::ArcGISRuntime::Renderer *renderer)

Sets the renderer to renderer.

See also renderer.

void DynamicEntityLayer::setSceneProperties(const Esri::ArcGISRuntime::LayerSceneProperties &sceneProperties)

Sets the sceneProperties to sceneProperties.

See also sceneProperties.

Esri::ArcGISRuntime::TrackDisplayProperties *DynamicEntityLayer::trackDisplayProperties() const

Returns the track display properties.

TrackDisplayProperties allow you to control the display of previous observations in a track by setting a maximum number of observations to show, displaying a line that connects them (track line), and applying renderers to the observations and/or track line.

void DynamicEntityLayer::unselectDynamicEntities(const QList<Esri::ArcGISRuntime::DynamicEntity *> &dynamicEntities)

Unselects the specified dynamic entities and removes them from the current list of selected dynamic entities.

dynamicEntities - The dynamic entities to remove from the selection.

void DynamicEntityLayer::unselectDynamicEntity(Esri::ArcGISRuntime::DynamicEntity *dynamicEntity)

Unselects the given dynamic entity and removes it from the current list of selected dynamic entities.

dynamicEntity - The dynamic entity to be unselected.

void DynamicEntityLayer::unselectDynamicEntityObservation(Esri::ArcGISRuntime::DynamicEntityObservation *dynamicEntityObservation)

Unselects the given dynamic entity observation and removes it from the current list of selected dynamic entity observations.

dynamicEntityObservation - The dynamic entity observation to be unselected.

void DynamicEntityLayer::unselectDynamicEntityObservations(const QList<Esri::ArcGISRuntime::DynamicEntityObservation *> &dynamicEntityObservations)

Unselects the specified dynamic entity observations and removes them from the current list of selected dynamic entity observations.

dynamicEntityObservations - The dynamic entity observations to remove from the selection.
