All Known Implementing Classes:

TLcdWFSFilteredModelFactory

public interface ILcdWFSFilteredModelFactory

A factory that creates filtered models. The factory takes an existing model as input, and returns a new model whose elements() method will return a subset of the original model's elements. The filtering criteria to be applied are provided as a TLcdWFSGetFeatureConstraints, and can include, among others, a filter encoded according to the OGC Filter specification. Note that if a request involves multiple feature types, the filtered model factory will be invoked once per feature type.
