OmvFeatureFilter interface

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

Signature:

export interface OmvFeatureFilter 

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.
