1.  trait PolygonalSummaryHandler[G <: Geometry, D, T] extends Serializable

   This trait provides the scaffolding necessary to generate aggregations which depend on Polygon and MultiPolygon instances.

   This trait provides the scaffolding necessary to generate aggregations which depend on Polygon and MultiPolygon instances.

   G

   the Geometry type against which containment and intersection checks are carried out to determine the flow of aggregation logic

   D

   the type of any data expected to be associated with G in Feature instances

   T

   the type being aggregated to through summary mergeOp calls

   Note

   This trait specifies the type of operation to be carried out but *NOT* the "zero element" which determines the beginning value for a chain of operations (like the starting element in a fold) and *NOT* the Polygon or MultiPolygon to be used during a summary. Instead, those are specified in a call to mergeOp which returns the function used in an actual summarization.
