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.

Files can be used for input or output. This can be specified in the constructor by choosing the flag type

Patterns::FileName::FileName | ( | const FileType | type = input | ) |
Constructor. The type of the file can be specified by choosing the flag.
|
virtual |
Return true
if the string matches its constraints, i.e. always.
Implements Patterns::PatternBase.
|
virtual |
Return a description of the pattern that valid strings are expected to match. Here, this is the string "[Filename]"
.
Implements Patterns::PatternBase.
|
virtual |
Return a copy of the present object, which is newly allocated on the heap. Ownership of that object is transferred to the caller of this function.
Implements Patterns::PatternBase.
|
static |
Creates new object if the start of description matches description_init. Ownership of that object is transferred to the caller of this function.
