TrellisData

Overview

The "TrellisData" object represents one part of data set in the query results, when the data set is trellised. If there was no use of the "trellis" drop zones, this will return only one element in the collection representing all the data in the query. It is an essential entity in determining the context for the APIs and therefore how to render each visual instance.
