/* This is the internal header file which contains important declarations for
* the collation framework.
* Ready to use collators are stored as binary images. Both UCA and tailorings
* share the same binary format. Individual files (currently only UCA) have a
* udata header in front of the image and should be opened using udata_open.
* Tailoring images are currently stored inside resource bundles and are intialized
* through ucol_open API.
*
* The following describes the formats for collation binaries
* (UCA & tailorings) and for the inverse UCA table.
* Substructures are described in the collation design document at
* http://source.icu-project.org/repos/icu/icuhtml/trunk/design/collation/ICU_collation_design.htm
*
* -------------------------------------------------------------
*
* Here is the format of binary collation image.
*
* Physical order of structures:
* - header (UCATableHeader)
* - options (UColOptionSet)
* - expansions (CE[])
* - contractions (UChar[contractionSize] + CE[contractionSize])
* - serialized UTrie with mappings of code points to CEs
* - max expansion tables (CE[endExpansionCECount] + uint8_t[endExpansionCECount])
* - two bit sets for backward processing in strcoll (identical prefixes)
* and for backward CE iteration (each set is uint8_t[UCOL_UNSAFECP_TABLE_SIZE])
* - UCA constants (UCAConstants)
* - UCA contractions (UChar[contractionUCACombosSize][contractionUCACombosWidth])
*
* UCATableHeader fields:
*
* int32_t size; - image size in bytes
*
* Offsets to interesting data. All offsets are in bytes.
* to get the address add to the header address and cast properly.
* Some offsets are zero if the corresponding structures are empty.
*
* Tailoring binaries that only set options and contain no mappings etc.
* will have all offsets 0 except for the options and expansion offsets,
* which give the position and length of the options array.
*
* uint32_t options; - offset to default collator options (UColOptionSet *),
* a set of 32-bit values. See declaration of UColOptionSet for more details
*
* uint32_t UCAConsts; - only used (!=0) in UCA image - structure which holds values for indirect positioning and implicit ranges
* See declaration of UCAConstants structure. This is a set of unsigned 32-bit values used to store
* important constant values that are defined in the UCA and used for building and runtime.
*
* uint32_t contractionUCACombos; - only used (!=0) in UCA image - list of UCA contractions. This is a zero terminated array of UChar[contractionUCACombosWidth],
* containing contractions from the UCA. These are needed in the build process to copy UCA contractions
* in case the base contraction symbol is tailored.
*
* uint32_t magic; - must contain UCOL_HEADER_MAGIC (formatVersion 2.3)
*
* uint32_t mappingPosition; - offset to UTrie (const uint8_t *mappingPosition). This is a serialized UTrie and should be treated as such.
* Used as a primary lookup table for collation elements.
*
* uint32_t expansion; - offset to expansion table (uint32_t *expansion). This is an array of expansion CEs. Never 0.
*
* uint32_t contractionIndex; - offset to contraction table (UChar *contractionIndex). Used to look up contraction sequences. Contents
* are aligned with the contents of contractionCEs table. 0 if no contractions.
*
* uint32_t contractionCEs; - offset to resulting contraction CEs (uint32_t *contractionCEs). When a contraction is resolved in the
* in the contractionIndex table, the resulting index is used to look up corresponding CE in this table.
* 0 if no contractions.
* uint32_t contractionSize; - size of contraction table in elements (both Index and CEs).
*
* Tables described below are used for Boyer-Moore searching algorithm - they define the size of longest expansion
* and last CEs in expansions.
* uint32_t endExpansionCE; - offset to array of last collation element in expansion (uint32_t *).
* Never 0.
* uint32_t expansionCESize; - array of maximum expansion sizes (uint8_t *)
* int32_t endExpansionCECount; - size of endExpansionCE. See UCOL_GETMAXEXPANSION
* for the usage model
*
* These two offsets point to byte tables that are used in the backup heuristics.
* uint32_t unsafeCP; - hash table of unsafe code points (uint8_t *). See ucol_unsafeCP function.
* uint32_t contrEndCP; - hash table of final code points in contractions (uint8_t *). See ucol_contractionEndCP.
*
* int32_t contractionUCACombosSize; - number of UChar[contractionUCACombosWidth] in contractionUCACombos
* (formatVersion 2.3)
* UBool jamoSpecial; - Jamo special indicator (uint8_t). If TRUE, Jamos are special, so we cannot use simple Hangul decomposition.
* UBool isBigEndian; - endianness of this collation binary (formatVersion 2.3)
* uint8_t charSetFamily; - charset family of this collation binary (formatVersion 2.3)
* uint8_t contractionUCACombosWidth; - number of UChars per UCA contraction in contractionUCACombos (formatVersion 2.3)
*
* Various version fields
* UVersionInfo version; - version 4 uint8_t
* UVersionInfo UCAVersion; - version 4 uint8_t
* UVersionInfo UCDVersion; - version 4 uint8_t
* UVersionInfo formatVersion; - version of the format of the collation binary
* same formatVersion as in ucadata.icu's UDataInfo header
* (formatVersion 2.3)
*
* uint8_t reserved[84]; - currently unused
*
* -------------------------------------------------------------
*
* Inverse UCA is used for constructing collators from rules. It is always an individual file
* and always has a UDataInfo header.
* here is the structure:
*
* uint32_t byteSize; - size of inverse UCA image in bytes
* uint32_t tableSize; - length of inverse table (number of uint32_t[3] rows)
* uint32_t contsSize; - size of continuation table (number of UChars in table)
*
* uint32_t table; - offset to inverse table (uint32_t *)
* Inverse table contains of rows of 3 uint32_t values. First two values are CE and a possible continuation
* the third value is either a code unit (if there is only one code unit for element) or an index to continuation
* (number of code units combined with an index).
* table. If more than one codepoint have the same CE, continuation table contains code units separated by FFFF and final
* code unit sequence for a CE is terminated by FFFE.
* uint32_t conts; - offset to continuation table (uint16_t *). Contains code units that transform to a same CE.
*
* UVersionInfo UCAVersion; - version of the UCA, read from file 4 uint8_t
* uint8_t padding[8]; - padding 8 uint8_t
* Header is followed by the table and continuation table.
