org.apache.druid.segment.AbstractDimensionSelector

All Implemented Interfaces:

HotLoopCallee, BaseDoubleColumnValueSelector, BaseFloatColumnValueSelector, BaseLongColumnValueSelector, BaseNullableColumnValueSelector, BaseObjectColumnValueSelector<Object>, ColumnValueSelector<Object>, DimensionDictionarySelector, DimensionSelector

Direct Known Subclasses:

PossiblyNullDimensionSelector

public abstract class AbstractDimensionSelector
extends Object
implements DimensionSelector

An abstract class that provides an implementation of getObject(). Don't extend this abstract class if you could provide a more efficient implementation for those methods, implement DimensionSelector directly then.
