Method Details

writeTo

public void writeTo(StreamOutput out)
             throws IOException

Throws:

IOException

getWriteableName

public String getWriteableName()

info

protected NodeInfo<? extends ChangePointExec> 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 ChangePointExec replaceChild(PhysicalPlan newChild)

Specified by:

replaceChild in class UnaryExec

computeReferences

protected AttributeSet computeReferences()

Description copied from class: QueryPlan

This very likely needs to be overridden for QueryPlan.references() to be correct when inheriting. This can be called on unresolved plans and therefore must not rely on calls to QueryPlan.output().

Overrides:

computeReferences in class QueryPlan<PhysicalPlan>

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

value

public Attribute value()

key

public Attribute key()

targetType

public Attribute targetType()

targetPvalue

public Attribute targetPvalue()

hashCode

public int hashCode()

Overrides:

hashCode in class UnaryExec

equals

public boolean equals(Object other)

Overrides:

equals in class UnaryExec
