replaceChild

public UnaryExec replaceChild(PhysicalPlan newChild)

Specified by:

replaceChild in class UnaryExec

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>

getWriteableName

public String getWriteableName()

Returns the name of the writeable object

probability

public Expression probability()

hashCode

public int hashCode()

Overrides:

hashCode in class UnaryExec

equals

public boolean equals(Object obj)

Overrides:

equals in class UnaryExec
