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

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>

nullable

public Nullability nullable()

Specified by:

nullable in class Expression

qualifier

public UnresolvedAttribute qualifier()

innerHashCode

protected int innerHashCode(boolean ignoreIds)

Overrides:

innerHashCode in class NamedExpression

innerEquals

protected boolean innerEquals(Object o,
 boolean ignoreIds)

Description copied from class: NamedExpression

The actual equality check, after shortcutting this == o and class checks.

Overrides:

innerEquals in class NamedExpression

unresolvedMessage

public String unresolvedMessage()

Description copied from interface: Unresolvable

NOTE: Any non-null return value from this method indicates that the item in question could not be resolved.

nodeString

public String nodeString()

Overrides:

nodeString in class NamedExpression

toString

public String toString()

Overrides:

toString in class NamedExpression
