Interface RandomFeatureAccess

  • All Superinterfaces:
    FeatureCollection<SimpleFeatureType,​SimpleFeature>, SimpleFeatureCollection
    All Known Implementing Classes:
    MemoryFeatureCollection, SubFeatureList

    public interface RandomFeatureAccess
    extends SimpleFeatureCollection
    Access Feature content using Feature "Id".

    Many SimpleFeatureCollection classes will make use of this API to avoid unnecessary caching of content. Supporting this interface will allow SubCollections to occur based on FeatureIds, with a suitable improvement in memory consumption.

    For an addition improvement in memory comsumption SubCollections may use of a sparse reprsentation where only (beginId,endId] ranges are kept in memory.
