Interface Summary

Interface	Description
ChunkedBackingStoreExposedWritableSource	Writable sources that use simple arrays to back contiguous regions may implement this interface, allowing callers to reach directly into their storage in order to fill them without the need for additional array copies.
ContextualizedObjectColumnSource<DATA_TYPE>	Interface for Object ColumnSources that offer an alternative get method that takes a context.
DeferredGroupingColumnSource<DATA_TYPE>	A column source that optionally makes available a provider for grouping metadata.
FillUnordered
InMemoryColumnSource	This is a marker interface for a column source that is entirely within memory; therefore select operations should not try to copy it into memory a second time.
PossiblyImmutableColumnSource	An interface for ColumnSources that can be marked immutable by the creator rather than as a fundamental property of their implementation.
ReverseLookupColumnSource<DATA_TYPE,EXTRA_VALUE_TYPE>	Common interface for column sources that provide a reverse-lookup function (value to int key).
SizedColumnSource<DATA_TYPE>	Interface for ColumnSources that know their size.
SizedContextualizedObjectColumnSource<DATA_TYPE>	Interface for ColumnSource implementations that are both SizedColumnSources and ContextualizedObjectColumnSources.
UngroupableColumnSource	Column sources that provide an array.

Class Summary

Class	Description
