Enclosing interface:

DefaultChunkSource<ATTR extends Attributes.Any>

public static interface DefaultChunkSource.SupportsContiguousGet<ATTR extends Attributes.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(ChunkSource.GetContext context, long firstKey, long lastKey)	Same as ChunkSource.getChunk(GetContext, OrderedKeys), except that you pass in the begin and last keys representing the begin and last (inclusive) keys of a single range rather than an OrderedKeys.
default Chunk<? extends ATTR>	getChunk(ChunkSource.GetContext context, OrderedKeys orderedKeys)	Returns a chunk of data corresponding to the keys from the given OrderedKeys.

Method Details

getChunk

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

Description copied from interface: ChunkSource

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

Specified by:

getChunk in interface ChunkSource<ATTR extends Attributes.Any>

Specified by:

getChunk in interface DefaultChunkSource<ATTR extends Attributes.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

orderedKeys - An OrderedKeys representing the keys to be fetched

Returns:

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

getChunk

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

Description copied from interface: ChunkSource

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

Specified by:

getChunk in interface ChunkSource<ATTR extends Attributes.Any>

Specified by:

getChunk in interface DefaultChunkSource<ATTR extends Attributes.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

Returns:

A chunk of data corresponding to the keys from the given range.
