@ManagedObject("Context Handler Collection")
public class ContextHandlerCollection
extends HandlerCollection

This HandlerCollection is creates a Map of contexts to it's contained handlers based on the context path and virtual hosts of any contained ContextHandlers. The contexts do not need to be directly contained, only children of the contained handlers. Multiple contexts may have the same context path and they are called in order until one handles the request.

ContextHandlerCollection

public ContextHandlerCollection(ContextHandler... contexts)

Method Details

mapContexts

@ManagedOperation("Update the mapping of context path to context")
public void mapContexts()

Remap the contexts. Normally this is not required as context mapping is maintained as a side effect of HandlerCollection.setHandlers(Handler[]) However, if configuration changes in the deep handler structure (eg contextpath is changed), then this call will trigger a remapping. This method is mutually excluded from deployHandler(Handler, Callback) and undeployHandler(Handler, Callback)

newHandlers

protected HandlerCollection.Handlers newHandlers(Handler[] handlers)

Overrides:

newHandlers in class HandlerCollection

handle

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

Description copied from interface: Handler

Handle a request.

Specified by:

handle in interface Handler

Overrides:

handle in class HandlerCollection

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

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

deployHandler

public void deployHandler(Handler handler,
 Callback callback)

Thread safe deploy of a Handler.

This method is the equivalent of HandlerCollection.addHandler(Handler), but its execution is non-block and mutually excluded from all other calls to deployHandler(Handler, Callback) and undeployHandler(Handler, Callback). The handler may be added after this call returns.

Parameters:

handler - the handler to deploy

callback - Called after handler has been added

undeployHandler

public void undeployHandler(Handler handler,
 Callback callback)

Thread safe undeploy of a Handler.

This method is the equivalent of HandlerCollection.removeHandler(Handler), but its execution is non-block and mutually excluded from all other calls to deployHandler(Handler, Callback) and undeployHandler(Handler, Callback). The handler may be removed after this call returns.

Parameters:

handler - The handler to undeploy

callback - Called after handler has been removed
