  15. def getFilterStrategy(filter: Filter, transform: Option[SimpleFeatureType]): Option[FilterStrategy]

    Gets options for a 'simple' filter, where each OR is on a single attribute, e.g.

    Gets options for a 'simple' filter, where each OR is on a single attribute, e.g. (bbox1 OR bbox2) AND dtg bbox AND dtg AND (attr = foo OR attr = bar) not: bbox OR dtg

    Because the input is simple, it can be satisfied with a single query filter.

    filter

    input filter

    transform

    attribute transforms

    returns

    a filter strategy which can satisfy the query, if available
