Method Detail

getOperatorType

public String getOperatorType()

Specified by:

getOperatorType in interface PhysicalOperator

isExecutable

public boolean isExecutable()

Description copied from interface: PhysicalOperator

Describes whether or not a particular physical operator can actually be executed. Most physical operators can be executed. However, Exchange nodes cannot be executed. In order to be executed, they must be converted into their Exec sub components.

Specified by:

isExecutable in interface PhysicalOperator

Overrides:

isExecutable in class AbstractBase

getNewWithChildren

public PhysicalOperator getNewWithChildren(List<PhysicalOperator> children)
                                    throws ExecutionSetupException

Description copied from interface: PhysicalOperator

Regenerate with this node with a new set of children. This is used in the case of materialization or optimization.

Specified by:

getNewWithChildren in interface PhysicalOperator

Throws:

ExecutionSetupException

iterator

public Iterator<PhysicalOperator> iterator()

Specified by:

iterator in interface Iterable<PhysicalOperator>

accept

public <T,X,E extends Throwable> T accept(PhysicalVisitor<T,X,E> physicalVisitor,
                                          X value)
                                   throws E extends Throwable

Description copied from interface: PhysicalOperator

Provides capability to build a set of output based on traversing a query graph tree.

Specified by:

accept in interface PhysicalOperator

Throws:

E extends Throwable

getColumns
