Enclosing class:

BufferPoolAllocator

public static class BufferPoolAllocator.Wrapped
extends io.netty.buffer.UnpooledUnsafeDirectByteBuf

A simple extension to UnpooledUnsafeDirectByteBuf that returns buffers to BufferPool on deallocate, and permits extracting the buffer from it to take ownership and use directly.
