Method Detail

matches

public boolean matches(java.lang.String protocol)

Specified by:

Parameters:

protocol -

true if the protocol is "http", false otherwise.

createRequest

public InboundHTTPRequest createRequest(IChannel channel)
                                 throws java.io.IOException

Description copied from interface: IMessageFactory

Create a new servlet request based on the channel. To faciliate low-level filtering, this method may return null, in which case the channel will be immediately forwarded to createResponse for generation of an error response.

Specified by:

createRequest in interface IMessageFactory

Parameters:

channel -

Returns:

a new InboundHTTPRequest.

Throws:

java.io.IOException

createResponse

public OutboundHTTPResponse createResponse(IChannel channel,
                                           InboundHTTPRequest request)
                                    throws java.io.IOException

Description copied from interface: IMessageFactory

Create a servlet response based on the given channel and request. If the request is null, assume that there is an error condition and create an appropriate http error response. The error response will be returned directly to the client without being dispatched to any user servlet. If null is returned, the channel will be closed immediately with no response at all returned to the client.

This is an internal GLUE api, and is subject to change without notice across minor revisions.

Specified by:

createResponse in interface IMessageFactory

Parameters:

channel -

request -

Returns:

a new OutboundHTTPResponse

Throws:

java.io.IOException
