    • isContiguous

      public boolean isContiguous()
      Deprecated.
      Description copied from class: ByteBuf
      Returns true if this ByteBuf implementation is backed by a single memory region. Composite buffer implementations must return false even if they currently hold ≤ 1 components. For buffers that return true, it's guaranteed that a successful call to ByteBuf.discardReadBytes() will increase the value of ByteBuf.maxFastWritableBytes() by the current readerIndex.

      This method will return false by default, and a false return value does not necessarily mean that the implementation is composite or that it is not backed by a single memory region.
