Constructor Detail

DictState

public DictState(org.apache.drill.exec.physical.resultSet.impl.LoaderInternals events,
                 ResultVectorCache vectorCache,
                 ProjectionFilter projectionSet)

Method Detail

bindColumnState

public void bindColumnState(ColumnState colState)

Overrides:

bindColumnState in class ContainerState

isVersioned

protected boolean isVersioned()

Description copied from class: TupleState.MapState

A map is within a union if the map vector has been materialized. Top-level maps are built at harvest time. But, due to the complexity of unions, maps within unions are materialized. This method ensures that maps are materialized regardless of nesting depth within a union.

Overrides:

isVersioned in class TupleState.MapState

Returns:

true if versioned

dump

public void dump(HierarchicalFormatter format)

Overrides:

dump in class TupleState.MapState
