/**
|
|
* An object implementing |nsIStyleRule| (henceforth, a rule) represents
|
|
* immutable stylistic information that either applies or does not apply
|
|
* to a given element. It belongs to an object or group of objects that
|
|
* implement |nsIStyleSheet| and |nsIStyleRuleProcessor| (henceforth, a
|
|
* sheet).
|
|
*
|
|
* A rule becomes relevant to the computation of style data when
|
|
* |nsIStyleRuleProcessor::RulesMatching| creates a rule node that
|
|
* points to the rule. (A rule node, |nsRuleNode|, is a node in the
|
|
* rule tree, which is a lexicographic tree indexed by rules. The path
|
|
* from the root of the rule tree to the |nsRuleNode| for a given
|
|
* |nsStyleContext| contains exactly the rules that match the element
|
|
* that the style context is for, in priority (weight, origin,
|
|
* specificity) order.)
|
|
*
|
|
* The computation of style data uses the rule tree, which calls
|
|
* |nsIStyleRule::MapRuleInfoInto| below.
|
|
*
|
|
* It is worth emphasizing that the data represented by a rule
|
|
* implementation are immutable. When the data need to be changed, a
|
|
* new rule object must be created. Failing to do this will lead to
|
|
* bugs in the handling of dynamic style changes, since the rule tree
|
|
* caches the results of |MapRuleInfoInto|.
|
|
*
|
|
* |nsIStyleRule| objects are owned by |nsRuleNode| objects (in addition
|
|
* to typically being owned by their sheet), which are in turn garbage
|
|
* collected (with the garbage collection roots being style contexts).
