| Summary | 0025308: TCollection_ExtendedString, NCollection_String - merge classes for string management | ||||
| Description | There are several classes for string management with different capabilities but similar usage scenarios: - TCollection_AsciiString. Main class for strings management in OCCT. NULL-terminated. Assumes fixed-length 1 byte long characters. Provides formatting tools (LeftAdjust/RightAdjust/LowerCase/Capitalize/UpperCase). Provides sub-string search tools. Does not aware of UTF-8, but can transparently store such strings. - TCollection_HAsciiString. Wrapper for TCollection_AsciiString for smart pointer creation. - TCollection_ExtendedString. This class has been originally designed to store wide (UNICODE) strings in OCCT, mostly used in OCAF persistence, but rarely outside. NULL-terminated. Assumes fixed-length 2 bytes long characters. Defines Standard_ExtCharacter as short, should be converted explicitly to wchar_t on Windows. Provides formatting tools (LeftAdjust/RightAdjust/LowerCase/Capitalize/UpperCase). Provides sub-string search tools. Expect string in UTF-16 encoding, but unaware of surrogate pairs. Has constructor from UTF-8 string (isMultiByte flag). - TCollection_HExtendedString. Wrapper for TCollection_ExtendedString for smart pointer creation. - NCollection_UtfString. Template class for UNICODE strings. Currently used in visualization for text rendering and interaction with FreeType. NULL-terminated. Assumes multibyte UNICODE characters (UTF8, UTF-16 or UTF32). Stores length (in UNICODE characters) and buffer size. Provides iterator NCollection_UtfIterator for efficient multibyte string processing (as alternative to accessing character by index). Provides methods to convert UNICODE string from/to system locale and between UNICODE variants (UTF-8/UTF-16/UTF-32). Does not provide string formatting capabilities. It is considered to revise these classes to eliminate code duplication. In addition, methods of class Resource_Unicode should be revised. | ||||
