11 | /* an intro to the data structure: |
|
|
12 | * |
|
|
13 | * vector keymap[] is grouped. |
|
|
14 | * |
|
|
15 | * inside each group, elements are sorted by the criteria given by compare_priority(). |
|
|
16 | * the lookup of keysym is done in two steps: |
|
|
17 | * 1) locate the group corresponds to the keysym; |
|
|
18 | * 2) do a linear search inside the group. |
|
|
19 | * |
|
|
20 | * array hash[] effectively defines a map from a keysym to a group in keymap[]. |
|
|
21 | * |
|
|
22 | * each group has its address(the index of first group element in keymap[]), |
|
|
23 | * which is computed and stored in hash[]. |
|
|
24 | * hash[] stores the addresses in the form of: |
|
|
25 | * index: 0 I1 I2 I3 In |
|
|
26 | * value: 0...0, A1...A1, A2...A2, A3...A3, ..., An...An |
|
|
27 | * where |
|
|
28 | * A1 = 0; |
|
|
29 | * Ai+1 = N1 + N2 + ... + Ni. |
|
|
30 | * it is computed from hash_budget_size[]: |
|
|
31 | * index: 0 I1 I2 I3 In |
|
|
32 | * value: 0...0, N1, 0...0, N2, 0...0, N3, ..., Nn, 0...0 |
|
|
33 | * 0...0, 0.......0, N1.....N1, N1+N2...N1+N2, ... (the compution of hash[]) |
|
|
34 | * or we can say |
|
|
35 | * hash_budget_size[Ii] = Ni; hash_budget_size[elsewhere] = 0, |
|
|
36 | * where |
|
|
37 | * set {I1, I2, ..., In} = { hashkey of keymap[0]->keysym, ..., keymap[keymap.size-1]->keysym } |
|
|
38 | * where hashkey of keymap[i]->keysym = keymap[i]->keysym & KEYSYM_HASH_MASK |
|
|
39 | * n(the number of groups) = the number of non-zero member of hash_budget_size[]; |
|
|
40 | * Ni(the size of group i) = hash_budget_size[Ii]. |
