Package sunlabs.brazil.filter Description

Filters are a type of handler, used by the filterHandler that can modify content after it has been obtained by another handler.

A filter is a special type of handler that has two additional methods, filter and shouldFilter. Normally, once a handler generates the content for a request, the content is delivered to the client, and the request is finished. Although this allows for a choice in the manner in which the content is obtained, nothing can be done to modify that content before it is transmitted to the client.

The filterHandler arranges for the content generated by another handler (or handlers) to be captured, allowing it to be filtered before it is sent to the client.
