Method Detail

rewriteWith

public static <C> PlanNode rewriteWith(ConnectorPlanRewriter<C> rewriter,
                                       PlanNode node)

rewriteWith

public static <C> PlanNode rewriteWith(ConnectorPlanRewriter<C> rewriter,
                                       PlanNode node,
                                       C context)

Parameters:

rewriter - Rewriter logic used to rewrite plans

node - Plan to be rewritten

Returns:

Rewritten plan node by using `rewriter`. Rewrites only need to specify implementation of nodes that are directly changed as of rewrite. All parents of rewritten nodes are automatically rewritten.

visitPlan

public PlanNode visitPlan(PlanNode node,
                          ConnectorPlanRewriter.RewriteContext<C> context)

Description copied from class: PlanVisitor

The default behavior to perform when visiting a PlanNode
