Detailed Description

A pattern that can be used to indicate when a parameter is intended to be the name of a directory. By itself, this class does not check whether the string that is given in a parameter file actually corresponds to an existing directory. Functionally, the class is therefore equivalent to the Anything class. However, it allows to specify the intent of a parameter.

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 to select or create a directory.

default

Constructor.

Member Function Documentation

match()

bool Patterns::DirectoryName::match ( const std::string &  test_string ) const

overridevirtual

Return true if the string matches its constraints, i.e. always.

Implements Patterns::PatternBase.

Definition at line 1601 of file patterns.cc.

description()

std::string Patterns::DirectoryName::description ( const OutputStyle  style = Machine ) const

overridevirtual

Return a description of the pattern that valid strings are expected to match. Here, this is the string "[Filename]".

Implements Patterns::PatternBase.

Definition at line 1609 of file patterns.cc.

clone()

std::unique_ptr< PatternBase > Patterns::DirectoryName::clone ( ) const

overridevirtual

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.

Definition at line 1637 of file patterns.cc.

create()

std::unique_ptr< DirectoryName > Patterns::DirectoryName::create ( const std::string &  description )

static

Create a new object if the start of description matches description_init. Ownership of that object is transferred to the caller of this function.

Definition at line 1645 of file patterns.cc.
