how to be sure if a string is valid for using with File ?

how to be sure if a string passed to File constructor is a valid path ?
parsing the command line and taking user input as a valid file path isn't safe
if i call File f(commandLine), cause if the user passes a wrong path String... i reach an assert in parseAbsolutePath, or worse in release mode i get called File::getCurrentWorkingDirectory().getChildFile (path).getFullPathName() with a wrong path... how can i be sure if a File can be constructed correctly ?
i thought the file would be constructed correctly, but calling to exists or existsAsFile would return false...

maybe add a isValid function ?

The assertion's just there as a hint that you're probably doing something silly, it doesn't mean that it'll fail to create the file object.

It's ok to create a file object with any path, regardless of whether it's a real path. There are plenty of methods for checking if the file exists after it's created.
