Do checks for a new (non-existent) file.

Public interface

Review Status

Date Reviewed:: yyyy/mm/dd

Etymology

Use this if you want a New File.

Synopsis

NewFile is a class checking if a new file already exists. If the file exists, then the user is asked via Choice::choice whether or not he or she wants to delete the file before using it.

Example

NewFile validFile; String newFileName("bigone"), error; Bool ok = validFile.valueOK(newFileName, error); if (!ok) { cout << error << endl; }

Motivation

Output file names are fairly common parameters, this consolidates the error checking and "remove if it already exists" logic.

To Do

We should probably make sure that the file is writable
