| 52 /* This is the internal header file which contains important declarations for |
| 53 * the collation framework. |
| 54 * Ready to use collators are stored as binary images. Both UCA and tailorings |
| 55 * share the same binary format. Individual files (currently only UCA) have a |
| 56 * udata header in front of the image and should be opened using udata_open. |
| 57 * Tailoring images are currently stored inside resource bundles and are intiali
zed |
| 58 * through ucol_open API. |
| 59 * |
| 60 * The following describes the formats for collation binaries |
| 61 * (UCA & tailorings) and for the inverse UCA table. |
| 62 * Substructures are described in the collation design document at |
| 63 * http://source.icu-project.org/repos/icu/icuhtml/trunk/design/collation/ICU_co
llation_design.htm |
| 64 * |
| 65 * ------------------------------------------------------------- |
| 66 * |
| 67 * Here is the format of binary collation image. |
| 68 * |
| 69 * Physical order of structures: |
| 70 * - header (UCATableHeader) |
| 71 * - options (UColOptionSet) |
| 72 * - expansions (CE[]) |
| 73 * - contractions (UChar[contractionSize] + CE[contractionSize]) |
| 74 * - serialized UTrie with mappings of code points to CEs |
| 75 * - max expansion tables (CE[endExpansionCECount] + uint8_t[endExpansionCECount
]) |
| 76 * - two bit sets for backward processing in strcoll (identical prefixes) |
| 77 * and for backward CE iteration (each set is uint8_t[UCOL_UNSAFECP_TABLE_SIZE
]) |
| 78 * - UCA constants (UCAConstants) |
| 79 * - UCA contractions (UChar[contractionUCACombosSize][contractionUCACombosWidth
]) |
| 80 * |
| 81 * UCATableHeader fields: |
| 82 * |
| 83 * int32_t size; - image size in bytes |
| 84 * |
| 85 * Offsets to interesting data. All offsets are in bytes. |
| 86 * to get the address add to the header address and cast properly. |
| 87 * Some offsets are zero if the corresponding structures are empty. |
| 88 * |
| 89 * Tailoring binaries that only set options and contain no mappings etc. |
| 90 * will have all offsets 0 except for the options and expansion offsets, |
| 91 * which give the position and length of the options array. |
| 92 * |
| 93 * uint32_t options; - offset to default collator options (UColOptionSet *), |
| 94 * a set of 32-bit values. See declaration of UColOptionSet
for more details |
| 95 * |
| 96 * uint32_t UCAConsts; - only used (!=0) in UCA image - structure which holds va
lues for indirect positioning and implicit ranges |
| 97 * See declaration of UCAConstants structure. This is a se
t of unsigned 32-bit values used to store |
| 98 * important constant values that are defined in the UCA a
nd used for building and runtime. |
| 99 * |
| 100 * uint32_t contractionUCACombos; - only used (!=0) in UCA image - list of UCA c
ontractions. This is a zero terminated array of UChar[contractionUCACombosWidth]
, |
| 101 * containing contractions from the UCA. These
are needed in the build process to copy UCA contractions |
| 102 * in case the base contraction symbol is tailo
red. |
| 103 * |
| 104 * uint32_t magic; - must contain UCOL_HEADER_MAGIC (formatVersion 2.3) |
| 105 * |
| 106 * uint32_t mappingPosition; - offset to UTrie (const uint8_t *mappingPosition)
. This is a serialized UTrie and should be treated as such. |
| 107 * Used as a primary lookup table for collation ele
ments. |
| 108 * |
| 109 * uint32_t expansion; - offset to expansion table (uint32_t *expansion). This
is an array of expansion CEs. Never 0. |
| 110 * |
| 111 * uint32_t contractionIndex; - offset to contraction table (UChar *contractionI
ndex). Used to look up contraction sequences. Contents |
| 112 * are aligned with the contents of contractionCEs
table. 0 if no contractions. |
| 113 * |
| 114 * uint32_t contractionCEs; - offset to resulting contraction CEs (uint32_t *co
ntractionCEs). When a contraction is resolved in the |
| 115 * in the contractionIndex table, the resulting inde
x is used to look up corresponding CE in this table. |
| 116 * 0 if no contractions. |
| 117 * uint32_t contractionSize; - size of contraction table in elements (both Index
and CEs). |
| 118 * |
| 119 * Tables described below are used for Boyer-Moore searching algorithm - they de
fine the size of longest expansion |
| 120 * and last CEs in expansions. |
| 121 * uint32_t endExpansionCE; - offset to array of last collation element in expan
sion (uint32_t *). |
| 122 * Never 0. |
| 123 * uint32_t expansionCESize; - array of maximum expansion sizes (uint8_t *) |
| 124 * int32_t endExpansionCECount; - size of endExpansionCE. See UCOL_GETMAXEXPANS
ION |
| 125 * for the usage model |
| 126 * |
| 127 * These two offsets point to byte tables that are used in the backup heuristics
. |
| 128 * uint32_t unsafeCP; - hash table of unsafe code points (uint8_t *). See ucol_u
nsafeCP function. |
| 129 * uint32_t contrEndCP; - hash table of final code points in contractions (uint8
_t *). See ucol_contractionEndCP. |
| 130 * |
| 131 * int32_t contractionUCACombosSize; - number of UChar[contractionUCACombosWidth
] in contractionUCACombos |
| 132 * (formatVersion 2.3) |
| 133 * UBool jamoSpecial; - Jamo special indicator (uint8_t). If TRUE, Jamos are spe
cial, so we cannot use simple Hangul decomposition. |
| 134 * UBool isBigEndian; - endianness of this collation binary (formatVersion 2.3) |
| 135 * uint8_t charSetFamily; - charset family of this collation binary (formatVersi
on 2.3) |
| 136 * uint8_t contractionUCACombosWidth; - number of UChars per UCA contraction in
contractionUCACombos (formatVersion 2.3) |
| 137 * |
| 138 * Various version fields |
| 139 * UVersionInfo version; - version 4 uint8_t |
| 140 * UVersionInfo UCAVersion; - version 4 uint8_t |
| 141 * UVersionInfo UCDVersion; - version 4 uint8_t |
| 142 * UVersionInfo formatVersion; - version of the format of the collation binary |
| 143 * same formatVersion as in ucadata.icu's UDataInf
o header |
| 144 * (formatVersion 2.3) |
| 145 * |
| 146 * uint32_t offset to the reordering code to lead CE byte remapping table |
| 147 * uint32_t offset to the lead CE byte to reordering code mapping table |
| 148 * |
| 149 * uint8_t reserved[76]; - currently unused |
| 150 * |
| 151 * ------------------------------------------------------------- |
| 152 * |
| 153 * Inverse UCA is used for constructing collators from rules. It is always an in
dividual file |
| 154 * and always has a UDataInfo header. |
| 155 * here is the structure: |
| 156 * |
| 157 * uint32_t byteSize; - size of inverse UCA image in bytes |
| 158 * uint32_t tableSize; - length of inverse table (number of uint32_t[3] rows) |
| 159 * uint32_t contsSize; - size of continuation table (number of UChars in table) |
| 160 * |
| 161 * uint32_t table; - offset to inverse table (uint32_t *) |
| 162 * Inverse table contains of rows of 3 uint32_t values. First
two values are CE and a possible continuation |
| 163 * the third value is either a code unit (if there is only one
code unit for element) or an index to continuation |
| 164 * (number of code units combined with an index). |
| 165 * table. If more than one codepoint have the same CE, continu
ation table contains code units separated by FFFF and final |
| 166 * code unit sequence for a CE is terminated by FFFE. |
| 167 * uint32_t conts; - offset to continuation table (uint16_t *). Contains code un
its that transform to a same CE. |
| 168 * |
| 169 * UVersionInfo UCAVersion; - version of the UCA, read from file 4 uint8_t |
| 170 * uint8_t padding[8]; - padding 8 uint8_t |
| 171 * Header is followed by the table and continuation table. |
