Class Declaration 

nsTDependentSubstring_CharT
A string class which wraps an external array of string characters. It
is the client code's responsibility to ensure that the external buffer
remains valid for a long as the string is alive.
NAMES:
nsDependentSubstring for wide characters
nsDependentCSubstring for narrow characters

GetData

PRUint32 GetData(const char**) const - source 
Get a const pointer to the string's internal buffer.  The caller
MUST NOT modify the characters at the returned address.
@returns The length of the buffer in characters.

Parameters

  • char** data

GetMutableData

PRUint32 GetMutableData(char**, PRUint32) - source 
Get a pointer to the string's internal buffer, optionally resizing
the buffer first.  If size_type(-1) is passed for newLen, then the
current length of the string is used.  The caller MAY modify the
characters at the returned address (up to but not exceeding the
length of the string).
@returns The length of the buffer in characters or 0 if unable to
satisfy the request due to low-memory conditions.

Parameters

  • char** data
  • PRUint32 newLen

SetIsVoid

void SetIsVoid(PRBool) - source 
string data is never null, but can be marked void.  if true, the
string will be truncated.  @see nsTSubstring::IsVoid

Parameters

  • PRBool <anonymous>

StripChar

void StripChar(char, PRInt32) - source 
This method is used to remove all occurrences of aChar from this
string.
@param  aChar -- char to be stripped
@param  aOffset -- where in this string to start stripping chars

Parameters

  • char aChar
  • PRInt32 aOffset
