Class Rule.Handler

java.lang.Object

org.eclipse.jetty.server.Request.Wrapper

org.eclipse.jetty.rewrite.handler.Rule.Handler

All Implemented Interfaces:

Content.Source, Request, Attributes

Direct Known Subclasses:

Rule.HttpURIHandler

Enclosing class:

Rule

public static class Rule.Handler
extends Request.Wrapper

A Request.Wrapper used to chain a sequence of Rules together.

The first Rule.Handler is initialized with the initial Request, then it is passed to a chain of Rules, which in turn chain Rule.Handlers together. At the end of the Rule applications, Rule.Handlers are chained so that so that the first rule produces the innermost Handler and the last rule produces the outermost Handler in this way: RH3(RH2(RH1(Req))).

After the Rule applications, the Rule.Handlers are then called in sequence, starting from the innermost and moving outwards with respect to the wrapping, until finally the Request.Handler.handle(Request, Response, Callback) method of the child Handler of RewriteHandler is invoked.

Method Details

handle

protected boolean handle(Response response,
 Callback callback)
                  throws Exception

Handles this wrapped request together with the passed response and callback.

This method should be overridden only if the rule applies to the response, or the rule completes the callback. By default this method forwards the handling to the next Rule.Handler. If a rule that overrides this method is non-terminating, it should call the super implementation to chain the rules.

Parameters:

response - the Response

callback - the Callback

Throws:

Exception - if there is a failure while handling the rules
