Constructor Details

Rename

public Rename(Source source,
 LogicalPlan child,
 List<Alias> renamings)

Method Details

writeTo

public void writeTo(StreamOutput out)

Specified by:

writeTo in interface Writeable

getWriteableName

public String getWriteableName()

Specified by:

getWriteableName in interface NamedWriteable

renamings

public List<Alias> renamings()

output

public List<Attribute> output()

Description copied from class: QueryPlan

The ordered list of attributes (i.e. columns) this plan produces when executed. Must be called only on resolved plans, otherwise may throw an exception or return wrong results.

Overrides:

output in class UnaryPlan

expressionsResolved

public boolean expressionsResolved()

Specified by:

expressionsResolved in class LogicalPlan

replaceChild

public UnaryPlan replaceChild(LogicalPlan newChild)

Specified by:

replaceChild in class UnaryPlan

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.

Specified by:

info in class Node<LogicalPlan>

hashCode

public int hashCode()

Overrides:

hashCode in class UnaryPlan

equals

public boolean equals(Object obj)

Overrides:

equals in class UnaryPlan
