Interface Summary

Interface	Description
BasicTableDataListener	Common base interface for table data listeners.
ColumnLocation	Per-TableLocation, per-column key and state object.
DeephavenFormatColumnLocation	ColumnLocation sub-interface for column locations stored in Deephaven's proprietary binary file format.

DeferredTableLocation.TableLocationCreator
FileAccessor	Interface to abstract-away local or remote file access.
GroupingProvider	Implementations of this interface are able to compute groupings.
KeyRangeGroupingProvider	Interface for GroupingProviders that operate on metadata derived from a ColumnLocation for a given Index key range.
ParquetFormatColumnLocation<ATTR extends Attributes.Any>	ColumnLocation sub-interface for column locations stored in the Apache Parquet columnar format.
ParquetFormatTableLocation	TableLocation sub-interface for table locations stored in the Apache Parquet columnar format.
TableKey	Interface that specifies key fields for any table-keyed object (i.e.
TableLocation	===================================================================================================================== Building block for Iris DB file-based tables, with helper methods for discovering locations and their sizes.
TableLocation.Listener	Listener interface for anything that wants to know about changes to a location.
TableLocationKey	Interface that specifies key fields for any TableLocation.
TableLocationProvider	Discovery utility for table locations for a given table.

Class Summary

Class	Description
AbstractColumnLocation<TLT extends TableLocation>	Partial ColumnLocation implementation for use by TableDataService implementations.
AbstractTableLocation<TKT extends TableKey,CLT extends ColumnLocation>	Partial TableLocation implementation for use by TableDataService implementations.
AbstractTableLocationProvider	Partial TableLocationProvider implementation for use by TableDataService implementations.
DeferredTableLocation
DeferredTableLocation.DataDriven	DeferredTableLocation that needs to initialize its inner location for all non-key methods.
DeferredTableLocation.SnapshotDriven	DeferredTableLocation that implements metadata getters by delegating to a snapshot.
FileDataBufferStore	Ordered buffer tracking system for a file, used to represent the data region of a column file.
FileDataBufferStore.StoredBufferMessage	Message implementation to wrap a stored buffer and associated boundaries.
FullTableLocationKey	Immutable class holding the information necessary to fully identify a table location (TableKey + TableLocationKey)
FullTableLocationKey.AggregateTableLocationKey	FullTableLocationKey representing all internal partition values.
FunctionConsistencyMonitor
FunctionConsistencyMonitor.ConsistentSupplier<T>	A supplier that uses a FunctionConsistencyMonitor to ensure that multiple invocations to the same function always return the same value, even if underlying conditions (like the date) change.
LazyFileAccessor	Lazily-initialized FileAccessor implementation.
OffsetFileAccessor<UFAT extends FileAccessor>	Wrap an underlying FileAccessor, providing an offset view into the underlying accessor's data.
RandomGroupingBuilder<DATA_TYPE>	Builder for constructing groupings from one or more <value, key range> pairs, with no requirement that key ranges be sequential.
SimpleTableLocationKey	Table location key for simple (i.e.
SingleTableLocationProvider	A TableLocationProvider that provides access to exactly one, previously-known TableLocation.
StandaloneTableKey	Table location key for simple standalone tables.
SubscriptionAggregator<LISTENER_TYPE extends BasicTableDataListener>	Implement optional subscription support suitable for multiple TableDataService components.

TableLocationLookupKey<TYPE extends CharSequence>	A simple implementation of TableLocationKey for use in hash lookups.
TableLocationLookupKey.Immutable
TableLocationLookupKey.Reusable
TableLocationProvider.Null	This is a fully functional TableLocationProvider that will not provide any locations.
TableLocationStateHolder	Tool for generic multi-field "atomic" get/set of state values for a table location.
TableLocationSubscriptionBuffer	Intermediates between push-based subscription to a TableLocationProvider and polling on LiveTable refresh.
TableLocationUpdateSubscriptionBuffer	Intermediates between push-based subscription to a TableLocation and polling on LiveTable refresh.
TableLookupKey<NAME_TYPE extends CharSequence>	A simple implementation of TableKey for use in hash lookups, or as a parent class for complex sub-classes.
TableLookupKey.Immutable	An immutable TableLookupKey
TableLookupKey.Reusable
WatchServiceTrial	This is simply a test / proof-of-concept of WatchServices.
