Enclosing interface:

DefaultChunkSource<ATTR extends Any>

public static interface DefaultChunkSource.SupportsContiguousGet<ATTR extends Any>
extends DefaultChunkSource<ATTR>

An alternative set of defaults which may typically be used by ChunkSources which support a get method which only works for contiguous ranges. They should just implement getChunk(GetContext, long, long).

Method Summary

Modifier and Type	Method	Description
Chunk<? extends ATTR>	getChunk(@NotNull ChunkSource.GetContext context, long firstKey, long lastKey)	Same as ChunkSource.getChunk(GetContext, RowSequence), except that you pass in the begin and last keys representing the begin and last (inclusive) keys of a single range rather than an RowSequence.
default Chunk<? extends ATTR>	getChunk(@NotNull ChunkSource.GetContext context, @NotNull RowSequence rowSequence)	Returns a chunk of data corresponding to the keys from the given RowSequence.

Method Details

getChunk

default Chunk<? extends ATTR> getChunk(@NotNull
 @NotNull ChunkSource.GetContext context,
 @NotNull
 @NotNull RowSequence rowSequence)

Description copied from interface: ChunkSource

Returns a chunk of data corresponding to the keys from the given RowSequence.

Specified by:

getChunk in interface ChunkSource<ATTR extends Any>

Specified by:

getChunk in interface DefaultChunkSource<ATTR extends Any>

Parameters:

context - A context containing all mutable/state related data used in retrieving the Chunk. In particular, the Context may be used to provide a Chunk data pool

rowSequence - An RowSequence representing the keys to be fetched

Returns:

A chunk of data corresponding to the keys from the given RowSequence

getChunk

Chunk<? extends ATTR> getChunk(@NotNull
 @NotNull ChunkSource.GetContext context,
 long firstKey,
 long lastKey)

Description copied from interface: ChunkSource

Same as ChunkSource.getChunk(GetContext, RowSequence), except that you pass in the begin and last keys representing the begin and last (inclusive) keys of a single range rather than an RowSequence. Typically you want to call this only if you don't have an RowSequence, such as during an RowSequence.forAllRowKeyRanges(LongRangeConsumer) call. In this case, it allows you to avoid creating an intermediary RowSequence object.

Specified by:

getChunk in interface ChunkSource<ATTR extends Any>

Specified by:

getChunk in interface DefaultChunkSource<ATTR extends Any>

Parameters:

context - A context containing all mutable/state related data used in retrieving the Chunk. In particular, the Context may be used to provide a Chunk data pool

firstKey - The beginning key (inclusive) of the range to fetch in the chunk

lastKey - The last key (inclusive) of the range to fetch in the chunk
