class ResolverRunner extends SQLConfHelper
Wrapper class for Resolver and single-pass resolution. This class encapsulates single-pass resolution and post-processing of resolved plan. This post-processing is necessary in order to either fully resolve the plan or stay compatible with the fixed-point analyzer.

- def resolve(plan: LogicalPlan, analyzerBridgeState: Option[AnalyzerBridgeState] = None): LogicalPlan
Entry point for the resolver.
Entry point for the resolver. This method performs following 3 steps:
- Resolves the plan in a bottom-up, single-pass manner.
- Validates the result of single-pass resolution.
- Applies necessary post-processing rules.
