From 146392647e3966c01ff6f4cadf0fb6808c53b161 Mon Sep 17 00:00:00 2001 From: maumar Date: Tue, 8 Jun 2021 16:03:48 -0700 Subject: [PATCH] query part - query apis for temporal operations - query root creator service that can now construct query root expressions in nav expansion tests for now are simply converted exisiting tests - used the original model & data - map entities to temporal in the model configuration - modify the data (remove or change values), - manually change the history table to make history deterministic (rather than based on current date), - added visitor to inject temporal operation to every query, which "time travels" to before the modifications above were made, so we should still get the same results as non-temporal & not modified data ---
