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 Casacore 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).
