Batch get chunking adapter

Method Summary

Modifier and Type	Method	Description
void	addChunkIntoContainer(java.nio.ByteBuffer byteBuffer, int chunkIndex, byte[] valueChunk)	Used to incrementally add a {@param valueChunk} into the {@param CHUNKS_CONTAINER} container.
java.nio.ByteBuffer	constructChunksContainer(ChunkedValueManifest chunkedValueManifest)	Used to construct the right kind of {@param CHUNKS_CONTAINER} container (according to the query code) to hold a large value which needs to be incrementally re-assembled from many smaller chunks.
MultiGetResponseRecordV1	constructValue(int schemaId, byte[] fullBytes)	This function can be implemented by the adapters which need fewer parameters.
MultiGetResponseRecordV1	constructValue(int schemaId, java.nio.ByteBuffer byteBuffer)	This function can be implemented by the adapters which need fewer parameters.
static MultiGetResponseRecordV1	get(AbstractStorageEngine store, int partition, java.nio.ByteBuffer key, boolean isChunked, ReadResponseStats response)
