Class RWCString has member functions to read, compare, store, restore,
concatenate, prepend, and append RWCStrings and char *’s. Operators allow
access to individual characters, with or without bounds checking. The details
of the RWCString class capabilities are summarized in the Class Reference,
Part 2.
5.2 Collation
The various comparison operators involving RWCString use case sensitive
lexicographic comparisons:
RWBoolean operator==(const RWCString&, const RWCString&);
RWBoolean operator!=(const RWCString&, const RWCString&);
RWBoolean operator< (const RWCString&, const RWCString&);
RWBoolean operator<=(const RWCString&, const RWCString&);
RWBoolean operator> (const RWCString&, const RWCString&);
RWBoolean operator>=(const RWCString&, const RWCString&);
If you wish to make case insensitive comparisons, then you use should use
member function:
int RWCString::compareTo( const RWCString& str,
caseCompare cmp = exact)
const;
which returns an integer -1, 0, or 1, depending on whether str is
lexicographically less than, equal to, or greater than self, respectively. The type
caseCompare is an enum with values
exact Case sensitive
ignoreCase Case insensitive
Its default setting is " exact " which gives the same result as the logical
operators ==, !=, etc.
For locale-specific string collations, use member function
int RWCString::collate(const RWCString& str) const;
