public interface Filter<T>
extends com.google.common.base.Predicate<T>, FlyweightPrototype<Filter<T>>

A filter is a strategy to decide whether to accept a given object or not. Typically T will be either a URI, an HttpResponse or a URIResponse. Technically it is identical to the Google Guava Predicate interface, but there are some conventions listed below that apply only to filters.

By contract, every filter that is an instance of a non-anonymous filter class is supposed to have a static method with the following signature

public static Filter<T> valueOf(String x)

that returns a filter (typically, a filter of its own kind) from a string. Moreover, it is required, for every filter class F and for every instance f, that toString() returns

classname(spec)

where

f.equals(F.valueOf(spec))

Note that classname can omit the package name if it is FILTER_PACKAGE_NAME.
