AsyncChannelWrapper (Apache Tomcat 9.0.117 API Documentation)
Description: declaration: package: org.apache.tomcat.websocket, interface: AsyncChannelWrapper

# 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.
