@ManagedObject("Handler of multiple handlers")
public class HandlerCollection
extends AbstractHandlerContainer

A collection of handlers.

The default implementations calls all handlers in list order, regardless of the response status or exceptions. Derived implementation may alter the order or the conditions of calling the contained handlers.

Method Detail

getHandlers

@ManagedAttribute(value="Wrapped handlers",
                  readonly=true)
public Handler[] getHandlers()

Returns:

Returns the handlers.

setHandlers

public void setHandlers(Handler[] handlers)

Parameters:

handlers - The handlers to set.

handle

public void handle(String target,
                   Request baseRequest,
                   HttpServletRequest request,
                   HttpServletResponse response)
            throws IOException,
                   ServletException

Description copied from interface: Handler

Handle a request.

Specified by:

Parameters:

target - The target of the request - either a URI or a name.

baseRequest - The original unwrapped request object.

request - The request either as the Request object or a wrapper of that request. The HttpConnection.getCurrentConnection().getHttpChannel().getRequest() method can be used access the Request object if required.

response - The response as the Response object or a wrapper of that request. The HttpConnection.getCurrentConnection().getHttpChannel().getResponse() method can be used access the Response object if required.

Throws:

IOException - if unable to handle the request or response processing

ServletException - if unable to handle the request or response due to underlying servlet issue
