Interface IParameterizedFeaturePainter

All Superinterfaces:

IFeaturePainter

public interface IParameterizedFeaturePainter
extends IFeaturePainter

A feature painter that can be used to specify how to paint a set of features using style expressions instead of specifying the options for each individual feature.

Note that this interface extends IFeaturePainter, which therefore still allows painting each feature individually. However, it is recommended to use style expressions whenever possible, for performance reasons.
