public class ProcessFilter
extends ResourceFilter

This filter process a normal entity body through any process.

Although, you would probably include the filtered resource inside a NegotiatedResource to make sure the target browser accepts this content-encoding.

Method Detail

getCommand

public java.lang.String[] getCommand()

Get the command we should process the reply stream through.

outgoingFilter

public ReplyInterface outgoingFilter(RequestInterface req,
                                     ReplyInterface rep)
                              throws ProtocolException

Process the request output through the provided process filter.

Overrides:

outgoingFilter in class ResourceFilter

Parameters:

req - The original request.
