Detailed Description

Basic definitions for ICU, for both C and C++ APIs.

This file defines basic types, constants, and enumerations directly or indirectly by including other header files, especially utf.h for the basic character and string definitions and umachine.h for consistent integer and other types.

Definition in file utypes.h.


Define Documentation

#define NULL   ((void *)0)

Define NULL if necessary, to 0 for C++ and to ((void *)0) for C.

Stable:
ICU 2.0

Definition at line 288 of file utypes.h.

Referenced by StringPiece::clear(), UnicodeSet::isFrozen(), UnicodeString::remove(), UnicodeString::removeBetween(), and UnicodeString::retainBetween().

#define U_ASCII_FAMILY   0

U_CHARSET_FAMILY is equal to this value when the platform is an ASCII based platform.

Stable:
ICU 2.0

Definition at line 105 of file utypes.h.

#define U_CALLCONV   U_EXPORT2

Similar to U_CDECL_BEGIN/U_CDECL_END, this qualifier is necessary in callback function typedefs to make sure that the calling convention is compatible.

This is only used for non-ICU-API functions. When a function is a public ICU API, you must use the U_CAPI and U_EXPORT2 qualifiers.

Stable:
ICU 2.0

Definition at line 276 of file utypes.h.

#define U_CHARSET_FAMILY   0

These definitions allow to specify the encoding of text in the char data type as defined by the platform and the compiler. It is enough to determine the code point values of "invariant characters", which are the ones shared by all encodings that are in use on a given platform.

Those "invariant characters" should be all the uppercase and lowercase latin letters, the digits, the space, and "basic punctuation". Also, '\n', '\r', '\t' should be available.

The list of "invariant characters" is:

    A-Z  a-z  0-9  SPACE  "  %  &amp;  '  (  )  *  +  ,  -  .  /  :  ;  <  =  >  ?  _


(52 letters + 10 numbers + 20 punc/sym/space = 82 total)

This matches the IBM Syntactic Character Set (CS 640).

In other words, all the graphic characters in 7-bit ASCII should be safely accessible except the following:

    '\' <backslash>
    '[' <left bracket>
    ']' <right bracket>
    '{' <left brace>
    '}' <right brace>
    '^' <circumflex>
    '~' <tilde>
    '!' <exclamation mark>
    '#' <number sign>
    '|' <vertical line>
    '$' <dollar sign>
    '@' <commercial at>
    '`' <grave accent>
Stable:
ICU 2.0

Definition at line 157 of file utypes.h.

#define U_CHARSET_IS_UTF8   0

Hardcode the default charset to UTF-8.

If this is set to 1, then

  • ICU will assume that all non-invariant char*, StringPiece, std::string etc. contain UTF-8 text, regardless of what the system API uses
  • some ICU code will use fast functions like u_strFromUTF8() rather than the more general and more heavy-weight conversion API (ucnv.h)
  • ucnv_getDefaultName() always returns "UTF-8"
  • ucnv_setDefaultName() is disabled and will not change the default charset
  • static builds of ICU are smaller
  • more functionality is available with the UCONFIG_NO_CONVERSION build-time configuration option (see unicode/uconfig.h)
  • the UCONFIG_NO_CONVERSION build option in uconfig.h is more usable
Draft:
This API may be changed in the future versions and was introduced in ICU 4.2

UCONFIG_NO_CONVERSION

#define U_COMMON_API   U_IMPORT

Definition at line 497 of file utypes.h.

#define U_ICUDATA_ENTRY_POINT   U_DEF2_ICUDATA_ENTRY_POINT(U_ICU_VERSION_MAJOR_NUM, U_ICU_VERSION_MINOR_NUM)

U_ICU_ENTRY_POINT is the name of the DLL entry point to the ICU data library.

Defined as a literal, not a string. Tricky Preprocessor use - ## operator replaces macro paramters with the literal string from the corresponding macro invocation, _before_ other macro substitutions. Need a nested #defines to get the actual version numbers rather than the literal text U_ICU_VERSION_MAJOR_NUM into the name. The net result will be something of the form #define U_ICU_ENTRY_POINT icudt19_dat

Stable:
ICU 2.4

#define U_ICUDATA_NAME   "icudt" U_ICU_VERSION_SHORT U_ICUDATA_TYPE_LETTER

i.e. 'icudt18e' for ICU 1.8.x on EBCDIC, etc..

Stable:

Typedef Documentation

typedef void* UClassID

UClassID is used to identify classes without using RTTI, since RTTI is not yet supported by all C++ compilers.

Each class hierarchy which needs to implement polymorphic clone() or operator==() defines two methods, described in detail below. UClassID values can be compared using operator==(). Nothing else should be done with them.

getDynamicClassID() is declared in the base class of the hierarchy as a pure virtual. Each concrete subclass implements it in the same way:
      class Base {
      public:
          virtual UClassID getDynamicClassID() const = 0;
      }

      class Derived {
      public:
          virtual UClassID getDynamicClassID() const
            { return Derived::getStaticClassID(); }
      }

Each concrete class implements getStaticClassID() as well, which allows clients to test for a specific type.

      class Derived {
      public:
          static UClassID U_EXPORT2 getStaticClassID();
      private:
          static char fgClassID;
      }

      // In Derived.cpp:
      UClassID Derived::getStaticClassID()
        { return (UClassID)&Derived::fgClassID; }
      char Derived::fgClassID = 0; // Value is irrelevant

typedef double UDate

Date and Time data type.

This is a primitive data type that holds the date and time as the number of milliseconds since 1970-jan-01, 00:00 UTC. UTC leap seconds are ignored.

ICU 2.0

Enumeration Type Documentation

enum UErrorCode

Error code to replace exception handling, so that the code is compatible with all C++ compilers, and to use the same mechanism for C and C++.

ICU functions that take a reference (C++) or a pointer (C) to a UErrorCode first test if(U_FAILURE(errorCode)) { return immediately; } so that in a chain of such functions the first one that sets an error code causes the following ones to not perform any operations.
Error codes should be tested using U_FAILURE() and U_SUCCESS().
