LeafPlan

All child nodes of this plan node

Return child expressions associated to this LogicalPlan node

Collect from all input expressions and report matching expressions

List all input expressions to the plan

Iterate through LogicalPlans and apply matching rules for transformation. The transformation will be applied to the current node as well.

Transform only child expressions

Transform child node only once

Apply transformOnce for all child nodes.

Recursively transform all nested expressions

Traverse the tree until finding the nodes matching the pattern. All nodes found from the root will be transformed, and no further recursive match will occur from the transformed nodes.

If you want to continue the transformation for the child nodes, use transformChildren or transformChildrenOnce inside the rule.

Depth-first transformation of expression

Recursively traverse plan nodes and apply the given function to LogicalPlan nodes

Recursively traverse the child plan nodes and apply the given function to LogicalPlan nodes

Recursively traverse the child plan nodes until the rule matches.

Recursively traverse the plan nodes until the rule matches.
