  info.informatica.text.FormatPrinter
      info.informatica.data.DataFormatter

public final class DataFormatter
extends info.informatica.text.FormatPrinter

Text formatting parser and printer.

This formatter emulates (not at 100%) the behavior of popular printf C function, adding a few extensions.
Instead of a varargs-style argument as in C, it uses a dataset.

Synopsis:
DataFormatter fmt = new DataFormatter("Cost of item number ${code,7.1d} ("${item,-40.50s}) is ${price,8.2f}.");
Dataset dset = new ResultsetDataset();
dset.set(myResultSet); String formatted_output = fmt.format(dset);
