The FairCom Server configuration file (or settings file or command line) can specify a server default for each type of extended segment definition supported. Each such default definition starts with a XTDKSEG_SEG_TYPE entry. For an ICU Unicode default, the entries begin with
XTDKSEG_SEG_TYPE UNICODE_ICU
This initial entry is then followed by the specifics of the default such as locale and other collation options. For example, the following configuration entries would define a default for the server with the same characteristics as the application default used in the above API example.
XTDKSEG_SEG_TYPE UNICODE_ICU
ICU_LOCALE "ar"
XTDKSEG_SRC_SIZE 12
XTDKSEG_SRC_TYPE UTF8
ICU_OPTION STRENGTH_TERTIARY
ICU_OPTION NORM_DEFAULT
The complete list of keywords and arguments is shown in the following table.
Configuration Keyword |
Arguments |
|---|---|
XTDKSEG_SEG_TYPE |
UNICODE_ICU |
XTDKSEG_SRC_TYPE |
PROVIDED UTF-8 UTF-16 |
XTDKSEG_SRC_SIZE |
PROVIDED COMPUTED <numeric value> |
XTDKSEG_FAILED_DEFAULT_OK |
YES [server can still begin if server default encounters an error] NO [server cannot continue on error, which is the default behavior] |
ICU_LOCALE |
<locale string in ICU form: xx_YY_Variant> * |
ICU_OPTION |
STRENGTH_PRIMARY STRENGTH_SECONDARY STRENGTH_TERTIARY STRENGTH_QUATERNARY STRENGTH_IDENTICAL STRENGTH_DEFAULT NORM_NONE NORM_CAN_DECMP NORM_CMP_DECMP NORM_CAN_DECMP_CMP NORM_CMP_DECMP_CAN NORM_DEFAULT LOCALE_SYSDEFAULT_NOTOK LOCALE_FALLBACK_NOTOK ATTR_FRENCH_ON ATTR_FRENCH_OFF ATTR_CASE_ON ATTR_CASE_OFF ATTR_DECOMP_ON ATTR_DECOMP_OFF ATTR_SHIFTED ATTR_NONIGNR ATTR_LOWER ATTR_UPPER ATTR_HANGUL |
* Where “xx” is the language as specified by ISO-639 (e.g., “fr” for French); ‘Y’ is a country as specified by ISO-3166 (e.g., “fr_CA” for French language in Canada); and the “Variant” portion represents system dependent options.
For all but ICU_OPTION, only one of the listed arguments can be specified for each keyword. For instance, it does not make sense to have both of these entries in the configuration file for one extended key segment default definition:
XTDKSEG_SRC_TYPE UTF16
XTDKSEG_SRC_TYPE UTF8
There may be many ICU_OPTION entries in a configuration file. Some combinations of entries do not make sense, and the behavior is not guaranteed if they are combined. For instance, using both of these entries is inappropriate:
ICU_OPTION ATTR_LOWER
ICU_OPTION ATTR_UPPER
