Interface PhysicalPlanConsumer

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface PhysicalPlanConsumer

Callback that receives one query's planned PhysicalNode, without executing it.

Used by QueryExecutor.plan(com.darkcollective.relix.semantic.SemanticModel, java.util.List<com.darkcollective.relix.ast.RelNode>, com.darkcollective.relix.events.QueryEventListener, com.darkcollective.relix.processor.internal.PhysicalPlanConsumer) to hand each query statement's physical plan object to the caller — unlike PlanConsumer, which renders the plan to text. A caller that needs the structured plan (e.g. to serialize it to JSON for the query bundle) uses this; a caller that only wants a human-readable rendering uses PlanConsumer.

Method Summary

Modifier and Type	Method	Description
void	accept(String label, PhysicalNode plan, PlanEstimates estimates)	Consumes one query's physical plan and the cardinality estimates that go with it.

Method Details

accept

void accept(String label,
 PhysicalNode plan,
 PlanEstimates estimates)

Consumes one query's physical plan and the cardinality estimates that go with it.

The estimates arrive separately because they are a side table, not a component of the nodes — see PlanEstimates.

Parameters:

label - the query's display label (relation name or "<expression N>")

plan - the planned physical tree

estimates - the per-node estimated row counts; never null, possibly empty
