## org.apache.catalina.connector
Class ResponseWrapper

    java.lang.Object
      |
      +--org.apache.catalina.connector.ResponseWrapper

All Implemented Interfaces:
  Response

Direct Known Subclasses:
  HttpResponseWrapper

public abstract class ResponseWrapper
extends java.lang.Object
implements Response

Abstract convenience class that wraps a Catalina-internal Response object. By default, all methods are delegated to the wrapped response, but subclasses can override individual methods as required to provide the functionality that they require.
