## org.apache.catalina.connector
Class RequestBase

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

All Implemented Interfaces:
  Request, javax.servlet.ServletRequest

Direct Known Subclasses:
  HttpRequestBase

public abstract class RequestBase
extends java.lang.Object
implements javax.servlet.ServletRequest, Request

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