public class CrystalOutputStream

extends FilterOutputStream

A stream for 'crystalizing' data so that it can be inserted into a database. This packs the data into a very long ASCII string, without using weird control characters. This helps a great deal for storing the data in long text objects. This should create data usable in any SQL database. The crystalized form is as follows: The input string is analyzed for text characters (not including 'x' or '!', which are used as special flags). Strings of such text are preceded by a '!' flag, and proceed until the next '!' or 'x' flag. Characters which are not text are converted to hexadecimal and preceded by an 'x' flag.
