All Implemented Interfaces:

RelDataTypeSystem

Enclosing class:

SqlOperatorTest

public static class SqlOperatorTest.CustomTimeFrameTypeSystem
extends DelegatingTypeSystem

Type system whose constructor reads from a thread-local. You must invoke the constructor in the same thread, but once constructed you can use from other threads.

It's a bit strange, but the best we can do to pass objects via Avatica's plugin system until [CALCITE-5295] Read the values of plugins (such as connect string properties) from ThreadLocal fields is fixed.
