Method Detail

visit

public void visit(TezPlanContainerVisitor v)
           throws VisitorException

Description copied from class: Operator

Visit this node with the provided visitor. This should only be called by the visitor class itself, never directly.

Specified by:

visit in class Operator<TezPlanContainerVisitor>

Parameters:

v - Visitor to visit with.

Throws:

VisitorException - if the visitor has a problem.

supportsMultipleInputs

public boolean supportsMultipleInputs()

Description copied from class: Operator

Indicates whether this operator supports multiple inputs.

Specified by:

supportsMultipleInputs in class Operator<TezPlanContainerVisitor>

Returns:

true if it does, otherwise false.

supportsMultipleOutputs

public boolean supportsMultipleOutputs()

Description copied from class: Operator

Indicates whether this operator supports multiple outputs.

Specified by:

supportsMultipleOutputs in class Operator<TezPlanContainerVisitor>

Returns:

true if it does, otherwise false.

public String name()

Specified by:

name in class Operator<TezPlanContainerVisitor>

getTezOperPlan

public TezOperPlan getTezOperPlan()

equals

public boolean equals(Object o)

Description copied from class: Operator

Compares to Operators based on their opKey

Overrides:

equals in class Operator<TezPlanContainerVisitor>

hashCode

public int hashCode()

Description copied from class: Operator

Needed to ensure that the list iterators' outputs are deterministic. Without this we are totally at object id's mercy.

Overrides:

hashCode in class Operator<TezPlanContainerVisitor>
