Constructor Details

Subquery

public Subquery(Source source,
 LogicalPlan child,
 Literal range,
 Literal resolution,
 Evaluation evaluation)

Method Details

range

public Literal range()

resolution

public Literal resolution()

evaluation

public Evaluation evaluation()

expressionsResolved

public boolean expressionsResolved()

Specified by:

expressionsResolved in class LogicalPlan

info

protected NodeInfo<Subquery> 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>

replaceChild

public Subquery replaceChild(LogicalPlan newChild)

Specified by:

replaceChild in class UnaryPlan

equals

public boolean equals(Object o)

Overrides:

equals in class UnaryPlan

hashCode

public int hashCode()

Overrides:

hashCode in class UnaryPlan

getWriteableName

public String getWriteableName()

Specified by:

getWriteableName in interface NamedWriteable

writeTo

public void writeTo(StreamOutput out)
             throws IOException

Specified by:

writeTo in interface Writeable

Throws:

IOException

returnType

public PromqlDataType returnType()

Description copied from interface: PromqlPlan

The PromQL return type of this plan node.

Specified by:

returnType in interface PromqlPlan
