Examples of org.geotools.feature.FeatureCollection.accepts()

org.geotools.feature.FeatureCollection.accepts()
Visit the contents of a feature collection.
The order of traversal is dependent on the FeatureCollection implementation; some collections are able to make efficient use of an internal index in order to quickly visit features located in the same region.
@param visitor Closure applied to each feature in turn. @param progress Used to report progress, may be used to interrupt the operation @since 2.5
