Constructor & Destructor Documentation

DString::DString (  const byte *  stream,
int  size,
int  def_encoding = -1
) 
 

Creates string from byte stream with encoding autodetecting.

Parameters:
stream Input raw byte stream, can't be null.
size Size of input buffer
def_encoding Default encoding to be used, if no other variants found.

DString::DString (  const char *  string,
int  s = 0,
int  l = -1,
int  encoding = -1
) 
 

String from single-byte character buffer.

Parameters:
string Character buffer, can't be null.
s Start string position. Zero - create from start of buffer.
l Length of created string. If -1, autodetects string length with last zero byte.
encoding Encoding, to use for char2unicode transformations. If -1, default encoding will be used.

DString::DString (  const wchar *  string,
int  s = 0,
int  l = -1
) 
 

String from unicode two-byte character buffer.

Parameters:
string Unicode character buffer, can't be null.
s Start string position. Zero - create from start of buffer.
l Length of created string. If -1, autodetects string length with last zero char.

DString::DString (  const w4char *  string,
int  s = 0,
int  l = -1
) 
 

String from UCS4 four-byte character buffer.

Parameters:
string UCS4 unicode character buffer, can't be null.
s Starting string position. Zero - create from start of buffer.
l Length of created string. If -1, autodetects string length with last zero char.

DString::DString (  const String *  cstring,
int  s = 0,
int  l = -1
) 
 

String from any String implementing interface.

Parameters:
cstring String class instance, can't be null.
s Starting string position.
l Length of created string. If -1, autodetects string length with cstring.length() call.

DString::DString (  const String &  cstring,
int  s = 0,
int  l = -1
) 
 

String from any String implementing interface.

Parameters:
cstring String class instance.
s Starting string position.
l Length of created string. If -1, autodetects string length with cstring.length() call.

Member Function Documentation

String* DString::substring (  int  s,
int  l = -1
)  const
 

Creates Dynamic string as substring of called object.

Parameters:
s Starting string position.
l Length of created string. If -1, creates string till end of current.
