Method Details

writeTo

public void writeTo(StreamOutput out)
             throws IOException

Throws:

IOException

replaceChild

public SubqueryExec replaceChild(PhysicalPlan newChild)

Specified by:

replaceChild in class UnaryExec

getWriteableName

public String getWriteableName()

info

protected NodeInfo<? extends PhysicalPlan> 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>

equals

public boolean equals(Object o)

Overrides:

equals in class UnaryExec

hashCode

public int hashCode()

Overrides:

hashCode in class UnaryExec
