35/* an intro to the data structure:
36 *
37 * vector keymap[] is grouped.
38 *
39 * inside each group, elements are sorted by the criteria given by compare_priority().
40 * the lookup of keysym is done in two steps:
41 * 1) locate the group corresponds to the keysym;
42 * 2) do a linear search inside the group.
43 *
44 * array hash[] effectively defines a map from a keysym to a group in keymap[].
45 *
46 * each group has its address(the index of first group element in keymap[]),
47 * which is computed and stored in hash[].
48 * hash[] stores the addresses in the form of:
49 * index: 0 I1 I2 I3 In
50 * value: 0...0, A1...A1, A2...A2, A3...A3, ..., An...An
51 * where
52 * A1 = 0;
53 * Ai+1 = N1 + N2 + ... + Ni.
54 * it is computed from hash_budget_size[]:
55 * index: 0 I1 I2 I3 In
56 * value: 0...0, N1, 0...0, N2, 0...0, N3, ..., Nn, 0...0
57 * 0...0, 0.......0, N1.....N1, N1+N2...N1+N2, ... (the compution of hash[])
58 * or we can say
59 * hash_budget_size[Ii] = Ni; hash_budget_size[elsewhere] = 0,
60 * where
61 * set {I1, I2, ..., In} = { hashkey of keymap[0]->keysym, ..., keymap[keymap.size-1]->keysym }
62 * where hashkey of keymap[i]->keysym = keymap[i]->keysym & KEYSYM_HASH_MASK
63 * n(the number of groups) = the number of non-zero member of hash_budget_size[];
64 * Ni(the size of group i) = hash_budget_size[Ii].
