Uses of SelectableColumn in org.apache.druid.segment.column

Subinterfaces of SelectableColumn in org.apache.druid.segment.column

Modifier and Type	Interface	Description
interface	BaseColumn
interface	ComplexColumn	This interface represents a complex column and can be implemented by druid extension writer of a custom column with arbitrary serialization instead of a custom column that serializes rows of objects serialized using GenericIndexed class which is default implementation of "writeToXXX" methods in ComplexColumnSerializer.
interface	DictionaryEncodedColumn<ActualType extends Comparable<? super ActualType>>
interface	NumericColumn

Modifier and Type	Class	Description
class	DoublesColumn
class	FloatsColumn
class	GenericIndexedBasedComplexColumn	Implementation of ComplexColumn to be used when complex column serialization is done by using GenericIndexed by using default implementations of "writeToXXX" methods in ComplexColumnSerializer
class	LongsColumn
class	StringUtf8DictionaryEncodedColumn	DictionaryEncodedColumn<String> for a column which has a ByteBuffer based UTF-8 dictionary.
class	UnknownTypeComplexColumn
