getTable

public TableHandle getTable()

getOutputSymbols

public List<Symbol> getOutputSymbols()

Specified by:

getOutputSymbols in class PlanNode

getAssignments

public Map<Symbol,ColumnHandle> getAssignments()

getEnforcedConstraint

public TupleDomain<ColumnHandle> getEnforcedConstraint()

A TupleDomain that represents a predicate that has been successfully pushed into this TableScan node. In other words, predicates that were removed from filters above the TableScan node because the TableScan node can guarantee it.

This field is used to make sure that predicates which were previously pushed down do not get lost in subsequent refinements of the table layout.

isUpdateTarget

public boolean isUpdateTarget()

getUseConnectorNodePartitioning

public Optional<Boolean> getUseConnectorNodePartitioning()

isUseConnectorNodePartitioning

public boolean isUseConnectorNodePartitioning()

getSources

public List<PlanNode> getSources()

Specified by:

getSources in class PlanNode

accept

public <R,C> R accept(PlanVisitor<R,C> visitor,
                            C context)

Overrides:

accept in class PlanNode

toString

public String toString()

Overrides:

toString in class Object

replaceChildren

public PlanNode replaceChildren(List<PlanNode> newChildren)

Specified by:

replaceChildren in class PlanNode

withUseConnectorNodePartitioning
