Filter

SerdSink *serd_filter_new(const SerdSink *target, const SerdNode *subject, const SerdNode *predicate, const SerdNode *object, const SerdNode *graph, bool inclusive)

Return a sink that filters out statements that do not match a pattern.

The returned sink acts like target in all respects, except that some statements may be dropped. If inclusive is true, then only statements that match the pattern are passed through. Otherwise, only statements that do not match the pattern are passed through.
