size_t index(const RWCRegexp& re,size_t*
ext, size_t i=0) const;
Regular expression matching. Returns the index greater than or equal to i of
the start of the first pattern that matches the regular expression re . Returns
RW_NPOS if there is no such pattern. The length of the matching pattern is
returned in the variable pointed to by ext .
RWCString& insert(size_t pos, const char* cs);
Insert a copy of the null-terminated string cs into self at position pos , thus
expanding the string. Returns a reference to self.
RWCString& insert(size_t pos, const char* cs,
size_t N);
Insert a copy of the first N characters of cs into self at position pos . Exactly N
characters are copied, including any embedded nulls. Hence, the buffer pointed to
by cs must be at least N bytes long. Returns a reference to self.
Returns a reference to self.
RWCString& insert(size_t pos, const RWCString&
str) ;
Insert a copy of the string str into self at position pos . Returns a reference to
self.
RWCString& insert(size_t pos, const RWCString&
str, size_t N);
Insert a copy of the first N characters or the length of str (whichever is less) of
str into self at position pos . Returns a reference to self.
RWBoolean isAscii() const;
Returns TRUE if self contains no characters with the high bit set.
RWBoolean isNull() const;
Returns TRUE if this is a zero lengthed string (i.e., the null string).
size_t last(char c) const;
Returns the index of the last occurrence in the string of the character c .
Returns RW_NPOS if there is no such character.
size_t length() const;
Return the number of bytes in self. Note that if self contains multibyte
characters, then this will not be the number of characters.
