org.apache.drill.exec.physical.impl.scan.project.VectorSource

Packages that use VectorSource

Package	Description
org.apache.drill.exec.physical.impl.scan.columns	Handles the special "columns" column used by the text reader, and available to similar readers.
org.apache.drill.exec.physical.impl.scan.file	Handles optional file metadata columns: implicit columns and partition columns.
org.apache.drill.exec.physical.impl.scan.project	Provides run-time semantic analysis of the projection list for the scan operator.

Uses of VectorSource in org.apache.drill.exec.physical.impl.scan.file

Classes in org.apache.drill.exec.physical.impl.scan.file that implement VectorSource

Modifier and Type	Class and Description
class	ImplicitColumnManager Manages the insertion of file metadata (AKA "implicit" and partition) columns.

Methods in org.apache.drill.exec.physical.impl.scan.file with parameters of type VectorSource

Modifier and Type	Method and Description
MetadataColumn	FileMetadataColumn.resolve(FileMetadata fileInfo, VectorSource source, int sourceIndex)
abstract MetadataColumn	MetadataColumn.resolve(FileMetadata fileInfo, VectorSource source, int sourceIndex)
MetadataColumn	PartitionColumn.resolve(FileMetadata fileInfo, VectorSource source, int sourceIndex)

Constructors in org.apache.drill.exec.physical.impl.scan.file with parameters of type VectorSource

Constructor and Description
FileMetadataColumn(String name, FileMetadataColumnDefn defn, FileMetadata fileInfo, VectorSource source, int sourceIndex) Constructor for resolved column.
MetadataColumn(String name, TypeProtos.MajorType type, String value, VectorSource source, int sourceIndex)
PartitionColumn(String name, int partition, FileMetadata fileInfo, VectorSource source, int sourceIndex)

Uses of VectorSource in org.apache.drill.exec.physical.impl.scan.project

Classes in org.apache.drill.exec.physical.impl.scan.project that implement VectorSource

Modifier and Type	Class and Description
class	NullColumnBuilder Manages null columns by creating a null column loader for each set of non-empty null columns.
class	ReaderSchemaOrchestrator Orchestrates projection tasks for a single reader within the set that the scan operator manages.
class	ResolvedTuple Drill rows are made up of a tree of tuples, with the row being the root tuple.
static class	ResolvedTuple.ResolvedDict
static class	ResolvedTuple.ResolvedDictArray
static class	ResolvedTuple.ResolvedMap Represents a map implied by the project list, whether or not the map actually appears in the table schema.
static class	ResolvedTuple.ResolvedMapArray Represents a map tuple (not the map column, rather the value of the map column.) When projecting, we create a new repeated map vector, but share the offsets vector from input to output.
static class	ResolvedTuple.ResolvedRow Represents the top-level tuple which is projected to a vector container.
static class	ResolvedTuple.ResolvedSingleDict
static class	ResolvedTuple.ResolvedSingleMap

Fields in org.apache.drill.exec.physical.impl.scan.project declared as VectorSource
