69 | |
70 | These Xrm routines allow very fast lookup of resources in the resource |
71 | database. Several usage patterns are exploited: |
72 | |
73 | (1) Widgets get a lot of resources at one time. Rather than look up each from |
74 | scratch, we can precompute the prioritized list of database levels once, then |
75 | search for each resource starting at the beginning of the list. |
76 | |
77 | (2) Many database levels don't contain any leaf resource nodes. There is no |
78 | point in looking for resources on a level that doesn't contain any. This |
79 | information is kept on a per-level basis. |
80 | |
81 | (3) Sometimes the widget instance tree is structured such that you get the same |
82 | class name repeated on the fully qualified widget name. This can result in the |
83 | same database level occuring multiple times on the search list. The code below |
84 | only checks to see if you get two identical search lists in a row, rather than |
85 | look back through all database levels, but in practice this removes all |
86 | duplicates I've ever observed. |

93 | |
94 | The Xrm representation has been completely redesigned to substantially reduce |
95 | memory and hopefully improve performance. |
96 | |
97 | The database is structured into two kinds of tables: LTables that contain |
98 | only values, and NTables that contain only other tables. |
99 | |
100 | Some invariants: |
101 | |
102 | The next pointer of the top-level node table points to the top-level leaf |
103 | table, if any. |
104 | |
105 | Within an LTable, for a given name, the tight value always precedes the |
106 | loose value, and if both are present the loose value is always right after |
107 | the tight value. |
108 | |
109 | Within an NTable, all of the entries for a given name are contiguous, |
110 | in the order tight NTable, loose NTable, tight LTable, loose LTable. |
