+ (Object) reduce_batch(edges, attr_hash)

Compute all AttrEdge edges given that { AttrKey => value } contains attribute values. Return new { AttrKey => value } hash with computed results, remove computed edges.

Instance Method Details

- (Object) reduce_batch(attr_hash)

Compute all internal AttrEdge edges given that { AttrKey => value } contains attribute values. Return new { AttrKey => value } hash with computed results, remove computed internal edges.
