## org.apache.catalina.connector
Class ResponseBase

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

All Implemented Interfaces:
  Response, javax.servlet.ServletResponse

Direct Known Subclasses:
  HttpResponseBase

public abstract class ResponseBase
extends java.lang.Object
implements Response, javax.servlet.ServletResponse

Convenience base implementation of the Response interface, which can be used for the Response implementation required by most Connectors. Only the connector-specific methods need to be implemented.
