Class InputStreamView

java.lang.Object

org.mojavemvc.views.InputStreamView

All Implemented Interfaces:

View

public class InputStreamView
extends Object
implements View

An instance of this class obtains the servlet's OutputStream, and copies the contents of the supplied InputStream to that stream. It sets the content type and content length (if available) before writing the content to the stream. It copies the contents using a buffer. This class is suitable for returning larger entities, such as files.

Description copied from interface: View

This method is invoked last in the sequence of steps involved in processing a request sent to the FrontController. The servlet request can be used to set any attributes, then to obtain a RequestDispatcher for forwarding or including, or the servlet response may be used to send a redirect, for example.

Users should note that any exceptions thrown from this method are not guaranteed to be caught in the FrontController. They may escape to the requestor. Users should handle any exceptions inside the implementation of this method if different behaviour is desired.

Specified by:

render in interface View

Parameters:

request - the servlet request

response - the servlet response

Throws:

javax.servlet.ServletException

IOException
