java.lang.Object
rife.engine.AbstractResponse
All Implemented Interfaces:
Response
Direct Known Subclasses:
HttpResponse, MockResponse
public abstract class AbstractResponse extends Object implements Response
This abstract class implements parts of the Response interface to provide behaviour that is specific to RIFE2.

Additional abstract methods have been provided to integrate with the concrete back-end classes that extend AbstractResponse.

      protected AbstractResponse(Request request)
      Constructor that needs to be called by all the constructors of the extending classes.
      Parameters:
      request - the Request that is associated with this response
      Since:
      1.0

  • Method Details

    • _setContentType

      protected abstract void _setContentType(String contentType)
      This method needs to be implemented by the extending back-end class and will be called by AbstractResponse during the RIFE2-specific additional behaviour. It behaves exactly like its counter-part in the Response interface.

      1.0
