Interface OmvFeatureFilter

The OmvFeatureFilter is designed to work in an OmvVisitor/visitOmv combination (for example, OmvDecoder).

remarks

Returning false from any of the calls terminates processing of that layer or feature.

The OmvFeatureFilter is an "early-opt-out" filter, which cannot filter individual features, because at that point the features are not really decoded. Use the OmvFeatureModifier to filter for individual features.
