* File resbund.cpp
|
|
*
|
|
* Modification History:
|
|
*
|
|
* Date Name Description
|
|
* 02/05/97 aliu Fixed bug in chopLocale. Added scanForLocaleInFile
|
|
* based on code taken from scanForLocale. Added
|
|
* constructor which attempts to read resource bundle
|
|
* from a specific file, without searching other files.
|
|
* 02/11/97 aliu Added UErrorCode return values to constructors. Fixed
|
|
* infinite loops in scanForFile and scanForLocale.
|
|
* Modified getRawResourceData to not delete storage in
|
|
* localeData and resourceData which it doesn't own.
|
|
* Added Mac compatibility #ifdefs for tellp() and
|
|
* ios::nocreate.
|
|
* 03/04/97 aliu Modified to use ExpandingDataSink objects instead of
|
|
* the highly inefficient ostrstream objects.
|
|
* 03/13/97 aliu Rewrote to load in entire resource bundle and store
|
|
* it as a Hashtable of ResourceBundleData objects.
|
|
* Added state table to govern parsing of files.
|
|
* Modified to load locale index out of new file distinct
|
|
* from default.txt.
|
|
* 03/25/97 aliu Modified to support 2-d arrays, needed for timezone data.
|
|
* Added support for custom file suffixes. Again, needed to
|
|
* support timezone data. Improved error handling to detect
|
|
* duplicate tags and subtags.
|
|
* 04/07/97 aliu Fixed bug in getHashtableForLocale(). Fixed handling of
|
|
* failing UErrorCode values on entry to API methods.
|
|
* Fixed bugs in getArrayItem() for negative indices.
|
|
* 04/29/97 aliu Update to use new Hashtable deletion protocol.
|
|
* 05/06/97 aliu Flattened kTransitionTable for HP compiler. Fixed usage of
|
|
* CharString.
|
|
* 06/11/99 stephen Removed parsing of .txt files.
|
|
* Reworked to use new binary format.
|
|
* Cleaned up.
|
|
* 06/14/99 stephen Removed methods taking a filename suffix.
|
|
* 06/22/99 stephen Added missing T_FileStream_close in parse()
|
|
* 11/09/99 weiv Added getLocale(), rewritten constructForLocale()

|
* Implementation Notes
|
|
*
|
|
* Resource bundles are read in once, and thereafter cached.
|
|
* ResourceBundle statically keeps track of which files have been
|
|
* read, so we are guaranteed that each file is read at most once.
|
|
* Resource bundles can be loaded from different data directories and
|
|
* will be treated as distinct, even if they are for the same locale.
|
|
*
|
|
* Resource bundles are lightweight objects, which have pointers to
|
|
* one or more shared Hashtable objects containing all the data.
|
|
* Copying would be cheap, but there is no copy constructor, since
|
|
* there wasn't one in the original API.
|
|
*
|
|
* The ResourceBundle parsing mechanism is implemented as a transition
|
|
* network, for easy maintenance and modification. The network is
|
|
* implemented as a matrix (instead of in code) to make this even
|
|
* easier. The matrix contains Transition objects. Each Transition
|
|
* object describes a destination node and an action to take before
|
|
* moving to the destination node. The source node is encoded by the
|
|
* index of the object in the array that contains it. The pieces
|
|
* needed to understand the transition network are the enums for node
|
|
* IDs and actions, the parse() method, which walks through the
|
|
* network and implements the actions, and the network itself. The
|
|
* network guarantees certain conditions, for example, that a new
|
|
* resource will not be closed until one has been opened first; or
|
|
* that data will not be stored into a TaggedList until a TaggedList
|
|
* has been created. Nonetheless, the code in parse() does some
|
|
* consistency checks as it runs the network, and fails with an
|
|
* U_INTERNAL_PROGRAM_ERROR if one of these checks fails. If the input
|
|
* data has a bad format, an U_INVALID_FORMAT_ERROR is returned. If you
|
|
* see an U_INTERNAL_PROGRAM_ERROR the transition matrix has a bug in
|
|
* it.
|
|
*
|
|
* Old functionality of multiple locales in a single file is still
|
|
* supported. For this reason, LOCALE names override FILE names. If
|
|
* data for en_US is located in the en.txt file, once it is loaded,
|
|
* the code will not care where it came from (other than remembering
|
|
* which directory it came from). However, if there is an en_US
|
|
* resource in en_US.txt, that will take precedence. There is no
|
|
* limit to the number or type of resources that can be stored in a
|
|
* file, however, files are only searched in a specific way. If
|
|
* en_US_CA is requested, then first en_US_CA.txt is searched, then
|
|
* en_US.txt, then en.txt, then default.txt. So it only makes sense
|
|
* to put certain locales in certain files. In this example, it would
|
|
* be logical to put en_US_CA, en_US, and en into the en.txt file,
|
|
* since they would be found there if asked for. The extreme example
|
|
* is to place all locale resources into default.txt, which should
|
|
* also work.
|
|
*
|
|
* Inheritance is implemented. For example, xx_YY_zz inherits as
|
|
* follows: xx_YY_zz, xx_YY, xx, default. Inheritance is implemented
|
|
* as an array of hashtables. There will be from 1 to 4 hashtables in
|
|
* the array.
|
|
*
|
|
* Fallback files are implemented. The fallback pattern is Language
|
|
* Country Variant (LCV) -> LC -> L. Fallback is first done for the
|
|
* requested locale. Then it is done for the default locale, as
|
|
* returned by Locale::getDefault(). Then the special file
|
|
* default.txt is searched for the default locale. The overall FILE
|
|
* fallback path is LCV -> LC -> L -> dLCV -> dLC -> dL -> default.
|
|
*
|
|
* Note that although file name searching includes the default locale,
|
|
* once a ResourceBundle object is constructed, the inheritance path
|
|
* no longer includes the default locale. The path is LCV -> LC -> L
|
|
* -> default.
|
|
*
|
|
* File parsing is lazy. Nothing is parsed unless it is called for by
|
|
* someone. So when a ResourceBundle for xx_YY_zz is constructed,
|
|
* only that locale is parsed (along with anything else in the same
|
|
* file). Later, if the FooBar tag is asked for, and if it isn't
|
|
* found in xx_YY_zz, then xx_YY.txt will be parsed and checked, and
|
|
* so forth, until the chain is exhausted or the tag is found.
|
|
*
|
|
* Thread-safety is implemented around caches, both the cache that
|
|
* stores all the resouce data, and the cache that stores flags
|
|
* indicating whether or not a file has been visited. These caches
|
|
* delete their storage at static cleanup time, when the process
|
|
* quits.
|
|
*
|
|
* ResourceBundle supports TableCollation as a special case. This
|
|
* involves having special ResourceBundle objects which DO own their
|
|
* data, since we don't want large collation rule strings in the
|
|
* ResourceBundle cache (these are already cached in the
|
|
* TableCollation cache). TableCollation files (.ctx files) have the
|
|
* same format as normal resource data files, with a different
|
|
* interpretation, from the standpoint of ResourceBundle. .ctx files
|
|
* are loaded into otherwise ordinary ResourceBundle objects. They
|
|
* don't inherit (that's implemented by TableCollation) and they own
|
|
* their data (as mentioned above). However, they still support
|
|
* possible multiple locales in a single .ctx file. (This is in
|
|
* practice a bad idea, since you only want the one locale you're
|
|
* looking for, and only one tag will be present
|
|
* ("CollationElements"), so you don't need an inheritance chain of
|
|
* multiple locales.) Up to 4 locale resources will be loaded from a
|
|
* .ctx file; everything after the first 4 is ignored (parsed and
|
|
* deleted). (Normal .txt files have no limit.) Instead of being
|
|
* loaded into the cache, and then looked up as needed, the locale
|
|
* resources are read straight into the ResourceBundle object.
|
|
*
|
|
* The Index, which used to reside in default.txt, has been moved to a
|
|
* new file, index.txt. This file contains a slightly modified format
|
|
* with the addition of the "InstalledLocales" tag; it looks like:
|
|
*
|
|
* Index {
|
|
* InstalledLocales {
|
|
* ar
|
|
* ..
|
|
* zh_TW
|
|
* }
|
|
* }
