Interface Summary

Interface	Description
NestedCommonFormatColumn	Base implementation for columns created with AutoTypeColumnSchema and handled with NestedCommonFormatColumnHandler to allow ease of merge via AutoTypeColumnMerger by providing a common implementation.
NestedPathPart

Class Summary

Class	Description
CompressedNestedDataComplexColumn<TStringDictionary extends Indexed<ByteBuffer>>	Implementation of NestedDataComplexColumn which uses a CompressedVariableSizedBlobColumn for the 'raw' StructuredData values and provides selectors for nested field columns specified by ordered lists of NestedPathPart.
DictionaryIdLookup	Value to dictionary id lookup, backed with memory mapped dictionaries populated lazily by the supplied
FieldTypeInfo	Binary serialization for nested field type info, translated into this compact format for storage in segments.
FieldTypeInfo.MutableTypeSet
FieldTypeInfo.TypeSet
FieldTypeInfo.Writer
GlobalDictionaryEncodedFieldColumnWriter<T>	Base class for writer of global dictionary encoded nested field columns for NestedDataColumnSerializer.
LocalDimensionDictionary
NestedCommonFormatColumn.Format
NestedCommonFormatColumnSerializer	Basic serializer implementation for the NestedCommonFormatColumn family of columns.
NestedDataColumnMetadata
NestedDataColumnSerializer	Serializer for NestedCommonFormatColumn which can store nested data.
NestedDataColumnSerializerV4
NestedDataColumnSupplier
NestedDataColumnSupplierV4
NestedDataColumnV3<TStringDictionary extends Indexed<ByteBuffer>>
NestedDataColumnV4<TStringDictionary extends Indexed<ByteBuffer>>
NestedDataColumnV5<TStringDictionary extends Indexed<ByteBuffer>>	Nested data column with optimized support for simple arrays.
NestedDataComplexColumn	Describes the basic shape for any 'nested data' (StructuredData) ComplexColumn implementation along with basic facilities for caching any columns created and methods for retrieving selectors for nested field columns.
NestedDataComplexTypeSerde
NestedDataComplexTypeSerde.NestedColumnFormatV4
NestedFieldColumnIndexSupplier<TStringDictionary extends Indexed<ByteBuffer>>	Supplies indexes for nested field columns NestedFieldDictionaryEncodedColumn of NestedDataComplexColumn.
NestedFieldDictionaryEncodedColumn<TStringDictionary extends Indexed<ByteBuffer>>

NestedPathField
NestedPathFinder
ScalarDoubleColumn	NestedCommonFormatColumn for ColumnType.DOUBLE
ScalarDoubleColumnAndIndexSupplier
ScalarDoubleColumnSerializer	Serializer for a ScalarDoubleColumn
ScalarDoubleFieldColumnWriter	Nested field writer for double type columns of NestedDataColumnSerializer.
ScalarLongColumn	NestedCommonFormatColumn for ColumnType.LONG
ScalarLongColumnAndIndexSupplier
ScalarLongColumnSerializer	Serializer for a ScalarLongColumn
ScalarLongFieldColumnWriter	Nested field writer for long type columns of NestedDataColumnSerializer.
ScalarNestedCommonFormatColumnSerializer<T>
ScalarStringColumnAndIndexSupplier
ScalarStringColumnSerializer	Serializer for a string NestedCommonFormatColumn that can be read with StringUtf8DictionaryEncodedColumn.
ScalarStringFieldColumnWriter	Nested field writer for string type columns of NestedDataColumnSerializer
SortedValueDictionary	Container to collect a set of sorted Indexed representing the global value dictionaries of some NestedDataComplexColumn, to later use with DictionaryMergingIterator to merge into a new global dictionary
StructuredData
StructuredDataJsonSerializer
StructuredDataProcessor
StructuredDataProcessor.ProcessedValue<T>
StructuredDataProcessor.ProcessResults	Accumulates the list of literal field paths and a rough size estimation for StructuredDataProcessor
ValueDictionary	Used by AutoTypeColumnIndexer to build the value dictionary, which can be converted into a SortedValueDictionary to sort and write out the values to a segment with ValueDictionary.getSortedCollector().
VariantArrayFieldColumnWriter	Nested field writer for array type columns of NestedDataColumnSerializer.
VariantColumn<TStringDictionary extends Indexed<ByteBuffer>>	NestedCommonFormatColumn for single type array columns, and mixed type columns.
VariantColumn.VariantVectorObjectSelector	Make a VectorObjectSelector for a dictionary encoded column that coerces mixed types to a common type
VariantColumnAndIndexSupplier
VariantColumnSerializer	Serializer for a NestedCommonFormatColumn for single type arrays and mixed type columns, but not columns with nested data.
VariantFieldColumnWriter	Nested field writer for mixed type scalar or array columns of NestedDataColumnSerializer.
