Method Details

info

protected NodeInfo<Project> info()

Description copied from class: Node

Normally, you want to use one of the static create methods to implement this.

For QueryPlans, it is very important that the properties contain all of the expressions and references relevant to this node, and that all the properties are used in the provided constructor; otherwise query plan transformations like QueryPlan#transformExpressionsOnly(Function) will not have an effect.

Overrides:

replaceChild

public Project replaceChild(LogicalPlan newChild)

Overrides:

expressionsResolved

public boolean expressionsResolved()

Overrides:
