Method Details

writeTo

public void writeTo(StreamOutput out)
             throws IOException

Throws:

IOException

getWriteableName

public String getWriteableName()

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 UnaryExec

isIntermediateAgg

public boolean isIntermediateAgg()

info

protected NodeInfo<? extends ExchangeSinkExec> 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<PhysicalPlan>

replaceChild

public ExchangeSinkExec replaceChild(PhysicalPlan newChild)

Specified by:

replaceChild in class UnaryExec

equals

public boolean equals(Object o)

Overrides:

equals in class UnaryExec

hashCode

public int hashCode()

Overrides:

hashCode in class UnaryExec
