The algorithm has three inputs錛堢畻娉曟湁涓変釜杈撳叆錛?
-
The outcome, that is, the value of an action attribute or the string resulting from the invocation of a method reference. action灞炴х殑鍊兼垨鑰呭紩鐢ㄦ柟娉曠殑榪斿洖緇撴灉錛堝瓧絎︿覆綾誨瀷錛?/p>
-
The view ID of the current view銆傚綋鍓嶈鍥?/p>
-
The action, that is, the literal value of the action attribute in the component that triggered the navigation.鐢ㄤ互瑙﹀彂瀵艱埅鐨勭粍浠跺睘鎬с?/p>
The first of two phases is to find the matching navigation-rule, following these steps錛堢浜岄樁孌電殑絎竴姝ュ氨鏄鎵劇鍚堢殑瀵艱埅瑙勫垯錛?
- If the outcome is null, return immediately and redisplay the current page.錛堝鏋渙utcome鏄┖錛屽垯绔嬪埢榪斿洖閲嶆柊鏄劇ず褰撳墠欏甸潰錛?
- Merge all navigation rules with the same from-view-id value.錛堝悎騫剁浉鍚宖rom-view-id鐨勫鑸鍒欙級
- Try to find a navigation rule whose from-view-id value matches the view ID exactly. If such a rule exists, take it.
- Consider all navigation rules whose from-view-id values end with a wildcard suffix, such as secure. For each such rule, check whether the prefix (after removing the *) is identical to the corresponding prefix of the view ID. If there are matching rules, take the one with the longest matching prefix.
- If there is a rule without a from-view-id, take it.錛堝鏋滄湁娌℃湁from-view-id鐨勮鍒欙紝浣跨敤錛?
- If there is no match at all, redisplay the current page.錛堝鏋滈兘娌℃湁絎﹀悎錛岄噸鏂版樉紺哄綋鍓嶉〉闈級
The second of two phases is to consider all navigation-case elements in the matching navigation rule (which may consist of several merged navigation-rule elements with matching from-view-id.values).
Follow these steps to find the matching case.
- If a case has both matching from-outcome and from-action, take it.
- Otherwise, if a case has matching from-outcome and no from-action, take it.
- Otherwise, if a case has matching from-action and no from-outcome, take it.
- Otherwise, if there is a case with neither from-outcome or from-action, take it.
- If there is no match at all, redisplay the current page.
Naturally, we recommend that you do not create tricky navigation rules in your own programs. As long as you stay away from wildcards and from-action elements, you won't need to know about the gory details of the navigation algorithm.
