All Implemented Interfaces:

NamedWriteable, Writeable, Resolvable

public class InSubquery
extends Expression

Unresolved expression for field IN (subquery) where the subquery is a full ES|QL query.

This node will be resolved by InSubqueryResolver into a concrete logical plan. InSubquery serves as the clean boundary between parsing and pre analysis, LogicalPlanBuilder creates an expression, InSubqueryResolver transforms it into a logical plan.

If any InSubquery expressions remain after InSubqueryResolver runs (i.e. they were used outside a WHERE clause), InSubqueryResolver raises a VerificationException.

InSubquery

public InSubquery(Source source,
 Expression value,
 LogicalPlan subquery)

Method Details

value

public Expression value()

subquery

public LogicalPlan subquery()

dataType

public DataType dataType()

Description copied from class: Expression

The DataType returned by executing the tree rooted at this expression. If Expression.typeResolved() returns an error then the behavior of this method is undefined. It may return a valid type. Or it may throw an exception. Or it may return a totally nonsensical type.

Specified by:

dataType in class Expression

nullable

public Nullability nullable()

Specified by:

nullable in class Expression

getWriteableName

public String getWriteableName()

writeTo

public void writeTo(StreamOutput out)

info

protected NodeInfo<InSubquery> 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<Expression>

replaceChildren

public Expression replaceChildren(List<Expression> newChildren)

Specified by:

replaceChildren in class Node<Expression>

hashCode

public int hashCode()

Overrides:

hashCode in class Node<Expression>

equals

public boolean equals(Object obj)

Overrides:

equals in class Node<Expression>
