Detailed Description

A helper class for finding files or directories, given paths which can be relative to various locations (e.g. the Chaste source tree root, the current directory, the Chaste test output directory, or an absolute path).

Definition at line 69 of file FileFinder.hpp.

Constructor & Destructor Documentation

FileFinder::FileFinder ( )

Default constructor for subclasses to use. They should call SetPath() in their constructor.

This also allows classes to store a FileFinder instance that hasn't been properly set up yet, and assign to it later using operator=.

Definition at line 78 of file FileFinder.cpp.

Referenced by CopyTo(), FindMatches(), GetParent(), and PrivateRemove().

FileFinder::FileFinder	(	const std::string &	rPath,
		RelativeTo::Value	relativeTo
	)

Main constructor.

Parameters

rPath	the path to the file/dir to find
relativeTo	how to interpret this path

Definition at line 83 of file FileFinder.cpp.

References SetPath().

FileFinder::FileFinder	(	const std::string &	rLeafName,
		const FileFinder &	rParentOrSibling
	)

Find a file (or folder) relative to some file or directory. If the second argument is a directory, we look for the given leaf name within it. If the second argument is a file, then we look for a sibling. An exception is raised if rParentOrSibling does not exist.

Parameters

rLeafName	the leaf name of the file/dir to find
rParentOrSibling	where to look for it

Definition at line 88 of file FileFinder.cpp.

References SetPath().

FileFinder::FileFinder ( const fs::path & rPath )

Conversion constructor from a Boost Filesystem path object. Note that since fs::path has a conversion constructor from std::string, this allows us to be initialised with a string or character constant, too. The path will be interpreted as relative to the current working directory, unless it is an absolute path.

Parameters

rPath the path to the file/dir to find

Definition at line 93 of file FileFinder.cpp.

References RelativeTo::Absolute, and SetPath().

FileFinder::~FileFinder ( )

virtual

Needed because we have virtual methods.

Member Function Documentation

FileFinder FileFinder::CopyTo ( const FileFinder & rDest ) const

Copy this file or folder (recursively in the latter case) to the given destination. If the destination is a folder that exists, the source will be copied with the same name inside that folder. Otherwise the source will be copied with the given destination name.

If the source is a file and the destination is a file that exists it will be removed prior to copying. If the source is a folder and the destination is a file that exists then an error is thrown.

Parameters

rDest where to copy to

Returns: a finder for the copied entity

void FileFinder::DangerousRemove ( ) const

This method will allow you to remove any file from under either * CHASTE_TEST_OUTPUT or * the source tree (but not elsewhere).

For this reason it is a very dangerous operation and should not be used if Remove could be instead.

BEWARE: if you have managed to set CHASTE_TEST_OUTPUT to "/" this could wipe your system!

void FileFinder::FakePath	(	RelativeTo::Value	fakeWhat,
		const std::string &	rFakePath
	)

static

For testing purposes, fake the value of one of the normally fixed paths, e.g. ChasteSourceRoot.

Parameters

fakeWhat	which path to fake
rFakePath	its fake value

std::vector< FileFinder > FileFinder::FindMatches ( const std::string & rPattern ) const

Returns: a list of files in this folder matching a simple glob pattern. This method must be called on a FileFinder that points at a folder, and the pattern will be matched against file (or folder) names in that folder. The pattern can use a subset of shell-style glob syntax. A '?' anywhere in the string matches any single character at that position. A '*' may be used at the start or end of the string to match any number of leading or trailing characters, respectively. Hidden files (names starting with a '.') will never be matched. Returns a sorted alphabetical list.

Parameters

rPattern the pattern to match names against

void FileFinder::PrivateRemove ( bool dangerous = false ) const

private

This is code common to Remove() and DangerousRemove(). Should remain private and not to be called from elsewhere. Remove() is only allowed to delete things with a .chaste_deletable_folder in the testoutput directory.

DangerousRemove() is allowed to delete anything in the source or testoutput directories.

Parameters

dangerous whether we are doing a dangerous remove.

Referenced by DangerousRemove(), and Remove().

void FileFinder::Remove ( ) const

Recursively remove this file or folder. Since this is a potentially very dangerous operation, only locations under the Chaste test output folder may be removed.

Only folders created by an OutputFileHandler, or the contents of such a folder, may be deleted (folders that have .chaste_deletable_folder present).

If you need to delete a file or folder without .chaste_deletable_folder, then you have to use DangerousRemove().
