Detailed Description

Compile time data owned by the UDR writer.

When attached to a UDRInvocationInfo object, keeps context between compiler interface calls for this object. This class can also be attached to a UDRPlanInfo object, to keep state between plan alternatives for a UDR invocation. The info is NOT passed to the run time methods, use UDRPlanInfo::addPlanData() for that.
