## Interface AsyncChannelWrapper

- All Known Implementing Classes:
    AsyncChannelWrapperNonSecure, AsyncChannelWrapperSecure

      public interface AsyncChannelWrapper

  This is a wrapper for a `AsynchronousSocketChannel` that limits the methods available thereby simplifying the process of implementing SSL/TLS support since there are fewer methods to intercept.
