info

protected NodeInfo<LocalRelation> 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.

Specified by:

info in class Node<LogicalPlan>

supplier

public LocalSupplier supplier()

hasEmptySupplier

public boolean hasEmptySupplier()

expressionsResolved

public boolean expressionsResolved()

Specified by:

expressionsResolved in class LogicalPlan

output

public List<Attribute> output()

Description copied from class: QueryPlan

The ordered list of attributes (i.e. columns) this plan produces when executed. Must be called only on resolved plans, otherwise may throw an exception or return wrong results.

Specified by:

output in class QueryPlan<LogicalPlan>

hashCode

public int hashCode()

Specified by:

hashCode in class LogicalPlan

equals

public boolean equals(Object obj)

Specified by:

equals in class LogicalPlan
