Interface StyleRuleMatcher

All Known Implementing Classes:

SimpleStyleRuleMatcher

public interface StyleRuleMatcher

A (possibly stateful) style matcher. This class is responsible for checking which style rule applies to the given document.

It is guaranteed, that the matcher receives the elements in the order in which they appear in the document.

Although the style rule matcher does not receive explicit element-opened and element-closed events, these events can be derived from the layout element and its relation to the parent (and possibly previously received element and its parent).
