Method Details

writeTo

public void writeTo(StreamOutput out)
             throws IOException

Throws:

IOException

getWriteableName

public String getWriteableName()

info

protected NodeInfo<UnresolvedStar> info()

Description copied from class: Node

Return the information about this 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 of 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>

nullable

public Nullability nullable()

Specified by:

nullable in class Expression

qualifier

public UnresolvedAttribute qualifier()

hashCode

public int hashCode()

Overrides:

hashCode in class NamedExpression

innerEquals

protected boolean innerEquals(Object o)

Overrides:

innerEquals in class NamedExpression

unresolvedMessage

public String unresolvedMessage()

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 NamedExpression

Parameters:

sb - target for the string

format - configuration for rendering the string representation

toString

public String toString()

Overrides:

toString in class NamedExpression
