Detailed Description

SubString help class to be used in at, before, .

Synopsis

The SubString class can only be used by the String class to be able to operate the aips++ defined replacement operators at, before, after, through, from. The class is used transparently in operations like:

        string.at(2,3) = "five";

If the SubString starts at a position outside the length of the original string (like e.g. in after(1000000)), a zero length string is created (not an exception thrown like in standard string operations).
