The
OmvFeatureModifiercan be used to filter individual features.It gets passed in the
Envof the feature, which contains all the values that can be searched for in a style. If a filter function returns false, the feature is ignored, and no geometry is being created.In addition to pure filtering, the
OmvFeatureModifiercan also modify the Env of the feature, or even add new properties to the feature, for example, traffic states. TheOmvFeatureModifieris executed before the styles are selected, so the geometry is created with the modified feature properties.
