The LongVcharObject class is a text string of any length that you can manipulate in your program. For storage, you can either place string objects as a long varchar data in a database, or in operating system files.

This class is useful when you have a text string that might be larger than the 2000-byte limit of varchar variables. When you use LongVcharObject objects, keep in mind that OpenROAD manipulates these objects in dynamically allocated memory. Therefore, you should not use them for very large amounts of text. For text that is always less than 200 bytes, a varchar variable is more efficient.
