Detailed Description

The DtVrvFilesystem is a wrapper around boost functions that are know to throw exceptions.

These functions are all reentrent* however the working directory should not be changed.

Member Function Documentation

static

Check if the given path is exists.

Parameters

Return values

true	if the given path exists in the filesystem.

	)

static

Check if the two given paths are equivalent.

This checks that two given paths, whether relative or absolute, both resolve to the same directory or file location.

static std::string makVrv::DtVrvFilesystem::makeRelative	(	const std::string &	root,
		const std::string &	path
	)

static

Resolve a given path into a relative path based on a specific root.

Using a root path location, a given path is converted to a new path relative to that root location.

For example: if the root is "C:\test" and path is "C:\temp\file.txt", the resulting path returned would be "..\file.txt".

The given root and given path values can be relative or absolute file or directory paths. If relative paths are given they are first converted to absolute paths from the current working directory.

Parameters

[in]	root	is the root path to base the relative path from.
[in]	path	is the path to convert to a relative path.

Returns: The given path converted to a relative path from the root.

Note: If the given root and path are on different devices, such as on different Windows disk drives, an absolute path is returned.; This function does not test existence of either path.

static std::string makVrv::DtVrvFilesystem::setExtension	(	std::string	file,
		std::string	ext
	)

static

Set a new extension to a file name.

If an extension already exists, it is changed to the new extension. If the file does not have an extension the new extension is appended.

Parameters

[in]	file	is the path or name of the file.
[in]	ext	is the extension to set on the filename.

Returns: The filename with the given extension.

Note: This function does not test existence of the file.

static std::string makVrv::DtVrvFilesystem::addExtension	(	std::string	file,
		std::string	ext
	)

static

Append a new extension to a file name.

If an existing extension to the file is the same as the given extension, the file is returned unchanged. If the given file or extension are invalid values, the file is returned unchanged.

Parameters

[in]	file	is the path or name of the file.
[in]	ext	is the extension to append to the filename.

Returns: The filename appended with the given extension.

Note: This function does not test existence of the file.
