Classes in org.apache.drill.exec.vector.accessor.writer that implement WriterPosition

Modifier and Type	Class	Description
class	AbstractArrayWriter	Writer for an array-valued column.
static class	AbstractArrayWriter.BaseArrayWriter
class	AbstractFixedWidthWriter	Base class for writers for fixed-width vectors.
static class	AbstractFixedWidthWriter.BaseFixedWidthWriter
static class	AbstractFixedWidthWriter.BaseIntWriter	Base class for writers that use the Java int type as their native type.
class	AbstractScalarWriterImpl	Column writer implementation that acts as the basis for the generated, vector-specific implementations.
class	AbstractTupleWriter	Implementation for a writer for a tuple (a row or a map.) Provides access to each column using either a name or a numeric index.
class	BaseScalarWriter	Column writer implementation that acts as the basis for the generated, vector-specific implementations.
class	BaseVarWidthWriter	Base class for variable-width (VarChar, VarBinary, etc.) writers.
class	BitColumnWriter	Specialized writer for bit columns.
class	DictEntryWriter	Writer for a Dict entry.
class	EmptyListShim	Internal implementation for a list of (possible) variants when the list has no type associated with it at all.
class	ListWriterImpl	List writer, which is basically an array writer, with the addition that each list element can be null.
class	MapWriter	Writer for a Drill Map type.
protected static class	MapWriter.ArrayMapWriter	Writer for a an array of maps.
protected static class	MapWriter.DummyArrayMapWriter
protected static class	MapWriter.DummyMapWriter
protected static class	MapWriter.SingleMapWriter	Writer for a single (non-array) map.
class	NullableScalarWriter
class	ObjectArrayWriter	Writer for an array of either a map or another array.
class	ObjectDictWriter	The implementation represents the writer as an array writer with special dict entry writer as its element writer.
class	OffsetVectorWriterImpl	Specialized column writer for the (hidden) offset vector used with variable-length or repeated vectors.
class	RepeatedListWriter	Implements a writer for a repeated list.
