16 // Modification History:
17 //
18 //  Date         Name          Description
19 //  2/5/97      aliu        Added streamIn and streamOut methods.  Added
20 //                          constructor which reads RuleBasedCollator object from
21 //                          a binary file.  Added writeToFile method which streams
22 //                          RuleBasedCollator out to a binary file.  The streamIn
23 //                          and streamOut methods use istream and ostream objects
24 //                          in binary mode.
25 //  6/30/97     helena      Added tests for CollationElementIterator::setText, getOffset
26 //                          setOffset and DecompositionIterator::getOffset, setOffset.
27 //                          DecompositionIterator is made public so add class scope
28 //                          testing.
29 //  02/10/98    damiba      Added test for compare(UnicodeString&, UnicodeString&, int32_t)
