Detailed Description

This file abstracts stuff that needs to be done when creating output files for tests. It defines some helpful functions, so that things that are otherwise repeated in lots of places are just done here.

Constructor & Destructor Documentation

OutputFileHandler::OutputFileHandler	(	const std::string &	rDirectory,
		bool	cleanOutputDirectory = `true`
	)

Create an OutputFileHandler that will create output files in the given directory. The directory name should be relative to the place where Chaste test output is stored. If the user needs to know where this is, use the GetChasteTestOutputDirectory method.

Will check that the directory exists and create it if needed.

Note:: This MUST be called collectively, since it contains a barrier call.

Parameters:

rDirectory	the directory to put output files in.
cleanOutputDirectory	whether to remove any existing files in the output directory

Definition at line 85 of file OutputFileHandler.cpp.

References CommonConstructor().

OutputFileHandler::OutputFileHandler	(	const FileFinder &	rDirectory,
		bool	cleanOutputDirectory = `true`
	)

Create an OutputFileHandler that will create output files in the given directory. This must be located inside the folder where Chaste test output is stored, and will typically be obtained with the FindFile method of this class from a parent handler.

Will check that the directory exists and create it if needed.

Note:: This MUST be called collectively, since it contains a barrier call.

Parameters:

rDirectory	the directory to put output files in
cleanOutputDirectory	whether to remove any existing files in the output directory

Member Function Documentation

void OutputFileHandler::AddTrailingSlash ( std::string & rDirectory ) [static, private]

Takes a reference to a string and adds a trailing slash if one is not already present

Parameters:

rDirectory The directory name to add a trailing slash to.

void OutputFileHandler::CommonConstructor	(	const std::string &	rDirectory,
		bool	cleanOutputDirectory
	)		`[private]`

Functionality common to both constructors.

Parameters:

rDirectory	relative path to the directory to put output files in
cleanOutputDirectory	whether to remove any existing files in the output directory

FileFinder OutputFileHandler::CopyFileTo ( const FileFinder & rSourceFile ) const

Copy the given file to this output directory.

Note:: This MUST be called collectively, since it contains a barrier call.

Parameters:

rSourceFile the file to copy

Returns:: the copied file

FileFinder OutputFileHandler::FindFile ( std::string leafName ) const

Get a FileFinder for a file in this output directory.

Parameters:

leafName the name of the file to find

std::string OutputFileHandler::GetChasteTestOutputDirectory ( ) [static]

Static method for getting the test output directory (the directory where chaste stores test output). This is set from the environment variable CHASTE_TEST_OUTPUT, and defaults to "./testoutput" if it is not set.

Attempts to return an absolute path, but may get confused by odd setups.

Static so an output file handler does not have to be created if the test output directory is wanted for, say, reading a file.

std::string OutputFileHandler::GetOutputDirectoryFullPath ( ) const

Return the full pathname to the directory this object will create files in.

std::string OutputFileHandler::MakeFoldersAndReturnFullPath ( const std::string & rDirectory ) const [private]

Check that the desired output directory exists and is writable by us. Create it if needed. Return the full pathname of the output directory.

The environment variable CHASTE_TEST_OUTPUT will be examined. If it is set and non-empty it is taken to be a directory where test output should be stored. Otherwise the current directory is used.

Note:: Contains a barrier, so must be called collectively.

Parameters:

rDirectory pathname of the output directory, relative to where Chaste output will be stored (user shouldn't care about this).

Returns:: full pathname to the output directory

out_stream OutputFileHandler::OpenOutputFile	(	const std::string &	rFileName,
		unsigned	number,
		const std::string &	rFileFormat,
		std::ios_base::openmode	mode = `std::ios::out \| std::ios::trunc`
	)		const

This just calls the other OpenOutputFile after concatenating the first three arguments together to make the full filename. For example OpenOutputFile("results_", 3, ".dat") creates results_3.dat. See documentation for OpenOutputFile(std::string, std::ios_base::openmode).

Parameters:

rFileName	the root name of the file to open
number	the number to append to the root name of the file
rFileFormat	the file format
mode	optionally, flags to use when opening the file (defaults are as for std::ofstream).

out_stream OutputFileHandler::OpenOutputFile	(	const std::string &	rFileName,
		std::ios_base::openmode	mode = `std::ios::out \| std::ios::trunc`
	)		const

Open an output file in our directory, and check it was opened successfully. Throws an Exception if not.

Parameters:

rFileName	the name of the file to open, relative to the output directory.
mode	optionally, flags to use when opening the file (defaults are as for std::ofstream).
