Detailed Description

A pattern that can be used to indicate when a parameter is intended to be the name of a file. By itself, this class does not check whether the string that is given in a parameter file actually corresponds to an existing file (it could, for example, be the name of a file to which you want to write output). Functionally, the class is therefore equivalent to the Anything class. However, it allows to specify the intent of a parameter. The flag given to the constructor also allows to specify whether the file is supposed to be an input or output file.

The reason for the existence of this class is to support graphical user interfaces for editing parameter files. These may open a file selection dialog if the filename is supposed to represent an input file.
