Detailed Description

Dedicated class for storing path to input and output files.

FilePath objects are constructed from given absolute or relative path to the file and its type (input or output). Before you create any instance of the class you have to call static method set_io_dirs to set:

working directory of the program (when it was started)
root input directory, i.e. directory of the main input file (given by -s parameter)
input directory, used to replace ${INPUT} placeholder (given by -i parameter)
output directory, where all output files should be placed (given by -o parameter)

Member Enumeration Documentation

enum FilePath::FileType

Possible types of file.

Enumerator
input_file
output_file

Definition at line 67 of file file_path.hh.

Constructor & Destructor Documentation

FilePath::FilePath ( )

Default constructor, necessary when using Input::Record::opt_val() to initialize a FilePath.

Definition at line 89 of file file_path.cc.

FilePath::FilePath	(	string	file_path,
		const FileType	ft
	)

Translates the given absolute or relative path to a file file_path depending on the file type ft.

For input files:

For relative path prepend absolute path of the directory of the main input file (root directory).
Replace ${INPUT} place holder with the input directory given at command line.

For output files:

Forbids absolute output paths.
For relative output path prepends it by the output directory given at the command line.

Definition at line 50 of file file_path.cc.

FilePath::FilePath	(	vector< string >	sub_paths,
		const FileType	ft
	)

Same as previous, but create path from vector of strings.

Definition at line 81 of file file_path.cc.

FilePath::FilePath ( string file_path )

Same as previous but implicitly use FileType::output_file.

Definition at line 85 of file file_path.cc.

Member Function Documentation

void FilePath::add_placeholder	(	string	key,
		string	value
	)

static

Add new item to place holder.

Placeholder is extended by adding a single new item. The item can be used in the name of the input or output file name. Currently, the only supported placeholder is ${INPUT}.

Example usage:: FilePath::add_placeholder_item("${SUBST_VAL}", "path/value");

Parameters

[in]	key	Key of new item.
[in]	value	Value of new item.

Definition at line 155 of file file_path.cc.

Here is the caller graph for this function:

string FilePath::convert_for_check_absolute ( string path )

staticprivate

Prepare path string for check absolute path.

Check first char of path string. If it is slash '/', add second slash char. Two slashes at begin is necessary for correct output of boost::filesystem::path.is_absolute() method for detection absolute path in unix format ("/home/x/y/z") under cygwin.

Definition at line 239 of file file_path.cc.

Here is the caller graph for this function:

void FilePath::create_dir ( const boost::filesystem::path & dir )

staticprivate

Create a directory, and check for exceptions.

Definition at line 256 of file file_path.cc.

Here is the caller graph for this function:

void FilePath::create_output_dir ( )

For an output filepath, the directory part (up to last separator) is extracted and all subdirectories are created if doesn't exist yet.

Definition at line 176 of file file_path.cc.

Here is the caller graph for this function:

string FilePath::cut_extension ( ) const

Return path to file with filename without extension.

Definition at line 203 of file file_path.cc.

FilePath::DECLARE_EXCEPTION	(	ExcFileOpen	,
		<< "Can not open file: "<< EI_Path::qval<< "\nAt input address: "<< EI_Address_String::qval
	)

FilePath::DECLARE_EXCEPTION	(	ExcAbsOutputPath	,
		<< "Can not set absolute path "<< EI_Path::qval<< " for an output file."
	)

FilePath::DECLARE_EXCEPTION	(	ExcMkdirFail	,
		<< "Can not create directory: "<< EI_Path::qval
	)

bool FilePath::exists ( ) const

Return true if the FilePath is a file.

Definition at line 228 of file file_path.cc.

string FilePath::extension ( ) const

Return extension of file.

Definition at line 198 of file file_path.cc.

Here is the caller graph for this function:

string FilePath::filename ( ) const

Return name of file with extension.

Definition at line 188 of file file_path.cc.

const string FilePath::get_absolute_working_dir ( )

static

Return absolute path of actual working directory.

Definition at line 171 of file file_path.cc.

template<class Stream >

template void FilePath::open_stream ( Stream & stream ) const

Open stream for this FilePath. Open mode is determined from the FilePath type.

Definition at line 211 of file file_path.cc.

Here is the caller graph for this function:

FilePath::operator string ( ) const

This class is implicitly convertible to string.

Definition at line 251 of file file_path.cc.

bool FilePath::operator== ( const FilePath & other ) const

Equality comparison operators for FilePaths.

Definition at line 266 of file file_path.cc.

string FilePath::parent_path ( ) const

Return path to file.

Definition at line 183 of file file_path.cc.

Here is the caller graph for this function:

void FilePath::set_dirs	(	const string	root,
		const string	input,
		const string	output
	)

static

Method for set input and output directories.

Set:

root directory (of the main input file)
input directory to replace ${INPUT} place holder
output directory used as prefix to the output files (relative output dirs are relative to the working directory)

Definition at line 102 of file file_path.cc.

Here is the caller graph for this function:

string FilePath::set_dirs_from_input	(	const string	main_yaml,
		const string	input,
		const string	output
	)

static

Same as previous, but in first argument accepts full path of yaml file and returns filename of this yaml file.

Set:

root directory (of the main yaml input file)
input directory to replace ${INPUT} place holder
output directory used as prefix to the output files (relative output dirs are relative to the working directory)
