Class Summary

Class	Description
AbstractBinaryRecordBatch<T extends PhysicalOperator>
AbstractRecordBatch<T extends PhysicalOperator>
AbstractSingleRecordBatch<T extends PhysicalOperator>	Implements an AbstractUnaryRecordBatch where the incoming record batch is known at the time of creation
AbstractTableFunctionRecordBatch<T extends PhysicalOperator>	Implements AbstractUnaryRecodBatch for operators that do not have an incoming record batch available at creation time; the input is typically set up a few steps after creation.
AbstractUnaryRecordBatch<T extends PhysicalOperator>	Base class for operators that have a single input.
BatchSchema	Historically BatchSchema is used to represent the schema of a batch.
BatchSchemaBuilder
ColumnConverter.ArrayColumnConverter	Converts and writes array values using ColumnConverter.ArrayColumnConverter.valueConverter into ColumnConverter.ArrayColumnConverter.arrayWriter.
ColumnConverter.DictColumnConverter	Converts and writes dict values using provided key / value converters.
ColumnConverter.DummyColumnConverter	Does nothing, is used when column is not projected to avoid unnecessary column values conversions and writes.
ColumnConverter.MapColumnConverter	Converts and writes all map children using provided ColumnConverter.MapColumnConverter.converters.
ColumnConverter.ScalarColumnConverter	Converts and writes scalar values using provided ColumnConverter.ScalarColumnConverter.valueConverter.

MaterializedField	Meta-data description of a column characterized by a name and a type (including both data type and cardinality AKA mode).
RawFragmentBatch
RecordBatchLoader	Holds record batch loaded from record batch message.
RecordBatchMemoryManager
RecordBatchSizer	Given a record batch or vector container, determines the actual memory consumed by each column, the average row, and the entire record batch.
RecordIterator	RecordIterator iterates over incoming record batches one record at a time.
SchemaBuilder	A reusable builder that supports the creation of BatchSchemas.
SchemalessBatch	Empty batch without schema and data.
SchemaUtil	Utility class for dealing with changing schemas
SimpleRecordBatch	Wrap a VectorContainer into a record batch.

VectorInitializer	Prototype mechanism to allocate vectors based on expected data sizes.
VectorInitializer.AllocationHint
WritableBatch	A specialized version of record batch that can moves out buffers and preps them for writing.
