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

GetData

PRUint32 GetData(const PRUnichar**) 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

PRUnichar** data

GetMutableData

PRUint32 GetMutableData(PRUnichar**, 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

PRUnichar** 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(PRUnichar, 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
