The advantage of this class is, that it handle all the memory managament for you - and it do it more efficient. If you assign a string to another string, the data of both strings are shared (without any copy operation or memory allocation) as long as you do not change the string. This class stores also the length of the string, so that many operations are faster as the C-str-functions. This class provide only readonly string handling. So you could create a string and you could only query the content from this string. It provide also functionality to change the string, but this results in every case in a new string instance (in the most cases with an memory allocation). You don't have functionality to change the content of the string. If you want change the string content, than you should us the OStringBuffer class, which provide these functionality and avoid to much memory allocation. The design of this class is similar to the string classes in Java and so more people should have fewer understanding problems when they use this class. </dd> </dl> <dl> <dt>File</dt>
