Member Function Documentation

detailLevelScales()

virtual void luciad::FeaturePainterMetadata::detailLevelScales ( std::vector< MapScale >  detailLevelScales )

pure virtual

Sets a vector of map scales that determine when this painter should switch from one level-of-detail to the next.

This can be used to advertise that this painter supports multiple level-of-details for a given object. The current level-of-detail that is used is determined by the map and is passed back to the IFeaturePainter via the FeaturePainterContext::getDetailLevel() method. When this method is not called, level-of-detail is not supported.

All scales smaller than the smallest scale will correspond to detail level '0' (least detailed). All scales larger than the largest scale will correspond to detail level 'detailLevelScales.size()' (most detailed).

Parameters

detailLevelScales

the switch scales for each level of detail

painterDependsOnFeature()

virtual void luciad::FeaturePainterMetadata::painterDependsOnFeature ( bool  depends )

pure virtual

Indicates whether a feature's style depends on the feature itself.

For example, the feature's color may depend on a certain data property. This value is true by default.

Parameters

depends

When true, a feature needs to be repainted by the painter when it changes.

painterDependsOnFeatureState()

virtual void luciad::FeaturePainterMetadata::painterDependsOnFeatureState ( const FeatureState &  featureState, bool  active  )

pure virtual

Indicates that a feature's style depends on the given state.

For example, the feature's color may change when it is selected. The luciad::FeatureState::selected() is active by default.

Parameters

featureState	The feature state on which the painter depends. When a feature's state changes to this state, it needs to be repainted by the painter.
active	The desired state of the given featureState.
