Description

ChunkBuffer is a useful abstraction over ByteBuffer to hide whether it's backed by a single ByteBuffer or multiple ones (IncrementalChunkBuffer). However, IncrementalChunkBuffer allocates its own ByteBuffer instances and only works with uniform buffer sizes. The goal of this task is to allow wrapping an existing List<ByteBuffer> in ChunkBuffer.
