Class BufferPoolAllocator.Wrapped

  • All Implemented Interfaces:
    io.netty.buffer.ByteBufConvertible, io.netty.util.ReferenceCounted, java.lang.Comparable<io.netty.buffer.ByteBuf>
    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.
