AddHandler()

TdjHandlerWrapper::AddHandler ( const IHandler Handler )

inherited

Add a handler to the container.

This implementation of AddHandler calls SetHandler with the passed handler. If this HandlerWrapper had a previous wrapped handler, then it is passed to a call to AddHandler on the passed handler.

Parameters

Handler

the handler to be added

Implements IHandlerContainer.

CheckStarted()

TdjLifeCycle::CheckStarted ( )

protectedinherited

Raises an exception if the lifecycle is in "started" state.

References TdjLifeCycle().

CheckStopped()

TdjLifeCycle::CheckStopped ( )

protectedinherited

Raises an exception if the lifecycle is in "stopped" state.

References TdjLifeCycle(), and Started.

ContextMatches()

Boolean TdjContextHandler::ContextMatches ( const string ConnectorName, const string Target )

protected

Check if the Document matches this context.

Parameters

ConnectorName	the connector name (like 'host:port'
Target	the target URL document

Returns

True if the context matches the connector name and target URL document

DoStart()

Handle()

TdjContextHandler::Handle ( const string Target, TdjServerContext Context, TdjRequest Request, TdjResponse Response )

protected

Handles an HTTP request.

Target	Target path or resource identifier
Context	Server context for this request
Request	HTTP request object
Response	HTTP response object to populate
