Detailed Description

The CDB abstract string class.

This class is defined to handle string literals. It is based on transcoder implementation of string_forward.h. For dynamic memory allocation the code of CDBcharacterVector is used. CDBstring is variant to other string literal classes. You can convert std::string, std::wstring and UnicodeString from and to CDBstring.

Member Function Documentation

char at (  size_t  pos  )  const

Receive one character from string (read).

char& at (  size_t  pos  )

Receive one character from string (read/write).

const char* c_str (   )  const

Reive C-string like literal. Receive pointer to a vector of Mchar characters. Returns: Pointer to a vector of Mchar's.

const char* strstr (  const CDBstring &  search  )

CDBstring substr (  int  istart, int  ifor )  const

Extract part of string (integer version). This method extracts a part of the corresponding string. It's behavoir is like substring(const iterator &, const iterator &). Parameters: istart  The position of the start character represented by integer. ifor  Length of the part. Returns: Copy of extracted content

CDBstring substr (  const iterator &  istart, const iterator &  iend )  const

Extract part of string. This method extracts a part of the corresponding string. Parameters: istart  The position of the start character represented by iterator. iend  The position of the end character represented by iterator. Returns: Copy of extracted content

int toAscii (  char *  dst, int  dst_size )  const

int toIcu (  UChar *  dst, int  dst_size )  const

int toUtf8 (  char *  dst, int  dst_size )  const

int toWchar (  wchar_t *  dst, int  dst_size )  const
