Package org.apache.flink.table.expressions.resolver

Class ExpressionResolver.PostResolverFactory

java.lang.Object
org.apache.flink.table.expressions.resolver.ExpressionResolver.PostResolverFactory
Enclosing class:
ExpressionResolver
@Internal public class ExpressionResolver.PostResolverFactory extends Object
Factory for creating resolved expressions after the actual resolution has happened. This is required when a resolved expression stack needs to be modified in later transformations.

Note: Further resolution or validation will not happen anymore, therefore the created expressions must be valid.
