 // 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.
