class ProjectResolver extends TreeNodeResolver[Project, LogicalPlan]

Resolves initially unresolved Project operator to either a resolved Project or Aggregate node, based on whether there are aggregate expressions in the project list. When LateralColumnAlias resolution is enabled, replaces the output operator with an appropriate operator structure using information from the scope. Detailed explanation can be found in buildProjectWithResolvedLCAs method.

    * Project introduces a new scope to resolve its subtree and project list expressions.

    * Project introduces a new scope to resolve its subtree and project list expressions. * During the resolution we determine whether the output operator will be Aggregate or * Project (based on the hasAggregateExpressions flag).

    If the output operator is Project and if lateral column alias resolution is enabled, we construct a multi-level Project, created from all lateral column aliases and their dependencies. Finally, we place the original resolved project on top of this multi-level one.

    After the subtree and project-list expressions are resolved in the child scope we overwrite current scope with resolved operators output to expose new names to the parent operators.
