referencesFeatureData

fun referencesFeatureData(): Boolean

True when this expression (or any sub-expression) reads per-feature data — i.e. its result can differ between two features in the same tile at the same zoom. That means a reference to a feature property (Get / Has), the feature's dynamic state (FeatureState), its geometry type (GeometryType), or its line-progress parameter (LineProgress).
