Spincast Routing plugin
default
Overview
The Spincast Routing plugin contains the Spincast router, which is an implementation
of the IRouter interface and one
of the most important component of a Spincast application.
It also provides a set of classes to help creating routes and manipulating them.
Finally, it provides an IRoutingRequestContextAddon
implementation, which is
a request context add-on giving your route handlers access to information about the current
routing process.
Installation
If you use the spincast-default artifact, this plugin is already installed so
you have nothing more to do!
If you start from scratch using the spincast-core artifact, you can use the
plugin by adding this Maven artifact to your project:
<dependency>
<groupId>org.spincast</groupId>
<artifactId>spincast-plugins-routing</artifactId>
<version>{{spincastCurrrentVersion}}</version>
</dependency>
You then install the plugin's Guice module, by passing it to the Guice.createInjector(...) method:
Injector guice = Guice.createInjector(
new SpincastCoreGuiceModule(args),
new SpincastRoutingPluginGuiceModule(IAppRequestContext.class)
// other modules...
);
... or by using the install(...) method from your custom Guice module:
public class AppModule extends SpincastCoreGuiceModule {
@Override
protected void configure() {
super.configure();
install(new SpincastRoutingPluginGuiceModule(getRequestContextType()));
// other modules...
}
// ...
}

The IRouteBuilder interface
When you start the creation of a route, for example using
router.GET("/"), a IRouteBuilder
instance is returned. You use this builder object to complete
the creation of your route.
Methods:
-
IRouteBuilder<R> id(String id)
An id that can be used to identify the route.
Must be unique.
-
IRouteBuilder<R> path(String path)
The path of the route.
-
IRouteBuilder<R> pos(int position)
The position of the handler. If "0", the handler is considered
as the *main* handler. Only one main handler per request
is run (the first one found)! The main handler is usually where
the body of the response is created.
A route with a position less than "0" is considered as a "before" filter and
will be run before the main handler. A route with a position greater than
"0" is considered as an "after" filter and will be run after the
main handler. All the matching before and after filters are run,
from the lower position to the higher. If two filters have the
same position, they will be run in order they have been added to
the router.
More than one position is allowed.
If not specified, "0" is used.
-
IRouteBuilder<R> found()
This route will be considered during a Found routing process.

The request context add-on
The plugin provides a IRoutingRequestContextAddon request context add-on. This add-on is
mounted as .routing() on the default Spincast request context.
Quick example :
public void myHandler(IAppRequestContext context) {
// Get information about the matches returned by
// the router.
IRoutingResult<IAppRequestContext> routingResult = context.routing().getRoutingResult();
}
Add-on methods :
-
boolean isNotFoundRoute()
Are we currently on a "Not Found" routing type?
-
boolean isExceptionRoute()
Are we currently on an "Exception" routing type?
-
boolean isForwarded()
Is the current route forwarded?
-
IRouteHandlerMatch<R> getCurrentRouteHandlerMatch()

as returned by the router.
-
int getPosition()
The current route handler position.
If < 0 : is a "before" handler.
If == 0 : is the main handler.
If > 0 : is an "after" handler.
