public class ViewUnionAll
extends UnionAll

A UnionAll produced by view resolution, as opposed to user-written subqueries. This type marker allows ViewResolver to distinguish between unions it has already processed (view-produced) and unions from the parser (subqueries) that may still contain unresolved view references.

Constructor Details

ViewUnionAll

public ViewUnionAll(Source source,
 LinkedHashMap<String,LogicalPlan> children,
 List<Attribute> output)

Method Details

replaceChildren

public LogicalPlan replaceChildren(List<LogicalPlan> newChildren)

Overrides:

replaceChildren in class UnionAll

info

protected NodeInfo<? extends LogicalPlan> 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:

info in class UnionAll

replaceSubPlans

public ViewUnionAll replaceSubPlans(List<LogicalPlan> subPlans)

Overrides:

replaceSubPlans in class UnionAll

replaceSubPlansAndOutput

public ViewUnionAll replaceSubPlansAndOutput(List<LogicalPlan> subPlans,
 List<Attribute> output)

Overrides:

replaceSubPlansAndOutput in class UnionAll

namedSubqueries

public Map<String,LogicalPlan> namedSubqueries()

nodeString

public void nodeString(StringBuilder sb,
 Node.NodeStringFormat format)

Description copied from class: Node

Append this Node's string representation to sb. This does not include this node's Node.children().

Overrides:

nodeString in class Node<LogicalPlan>

Parameters:

sb - target for the string

format - configuration for rendering the string representation

hashCode

public int hashCode()

Overrides:

hashCode in class UnionAll

equals

public boolean equals(Object o)

Overrides:

equals in class UnionAll
