// Representation of a condition in the Declarative WebRequest API. A condition
// consists of several attributes. Each of these attributes needs to be
// fulfilled in order for the condition to be fulfilled.
//
// We distinguish between two types of conditions:
// - URL Matcher conditions are conditions that test the URL of a request.
//   These are treated separately because we use a URLMatcher to efficiently
//   test many of these conditions in parallel by using some advanced
//   data structures. The URLMatcher tells us if all URL Matcher conditions
//   are fulfilled for a WebRequestCondition.
// - All other conditions are represented as WebRequestConditionAttributes.
//   These conditions are probed linearly (only if the URL Matcher found a hit).
//
// TODO(battre) Consider making the URLMatcher an owner of the
// URLMatcherConditionSet and only pass a pointer to URLMatcherConditionSet
// in url_matcher_condition_set(). This saves some copying in
// WebRequestConditionSet::GetURLMatcherConditionSets.
