Interface LayerFeatureConstraints

All Known Implementing Classes:

LayerFeatureConstraints_Impl

public interface LayerFeatureConstraints

The LayerFeatureConstraints element is optional in a NamedLayer and allows the user to specify constraints on what features of what feature types are to be selected by the named-layer reference. It is essentially a filter that allows the selection of fewer features than are present in the named layer.
