Detailed Description

A file utility class.

A file specification class that divides paths up into a directory and basename. These string values of the paths are put into uniqued string pools for fast comparisons and efficient memory usage.

Another reason the paths are split into the directory and basename is to allow efficient debugger searching. Often in a debugger the user types in the basename of the file, for example setting a breakpoint by file and line, or specifying a module (shared library) to limit the scope in which to execute a command. The user rarely types in a full path. When the paths are already split up, it makes it easy for us to compare only the basenames of a lot of file specifications without having to split up the file path each time to get to the basename.

◆ FileSpec() [2/3]

FileSpec::FileSpec	(	llvm::StringRef	path,

Constructor with path.

Takes a path to a file which can be just a filename, or a full path. If path is not nullptr or empty, this function will call FileSpec::SetFile (const char *path).

Parameters

[in]	path	The full or partial path to a file.
[in]	style	The style of the path

◆ Compare()

int FileSpec::Compare	(	const FileSpec &	lhs,
		const FileSpec &	rhs,
		bool	full
	)

static

Compare two FileSpec objects.

If full is true, then both the directory and the filename must match. If full is false, then the directory names for lhs and rhs are only compared if they are both not empty. This allows a FileSpec object to only contain a filename and it can match FileSpec objects that have matching filenames with different paths.

Parameters

[in]	lhs	A const reference to the Left Hand Side object to compare.
[in]	rhs	A const reference to the Right Hand Side object to compare.
[in]	full	If true, then both the directory and filenames will have to match for a compare to return zero (equal to). If false and either directory from lhs or rhs is empty, then only the filename will be compared, else a full comparison is done.

Returns: -1 if lhs is less than rhs, 0 if lhs is equal to rhs, 1 if lhs is greater than rhs

◆ GetPath() [2/3]

size_t FileSpec::GetPath	(	char *	path,
		size_t	max_path_length,
		bool	denormalize = `true`
	)		const

Extract the full path to the file.

Extract the directory and path into a fixed buffer. This is needed as the directory and path are stored in separate string values.

Parameters

[out]	path	The buffer in which to place the extracted full path.
[in]	max_path_length	The maximum length of path.

Returns: Returns the number of characters that would be needed to properly copy the full path into path. If the returned number is less than max_path_length, then the path is properly copied and terminated. If the return value is >= max_path_length, then the path was truncated (but is still NULL terminated).

◆ GetPathAsConstString()

◆ RemoveLastPathComponent()

bool FileSpec::RemoveLastPathComponent ( )

Removes the last path component by replacing the current path with its parent.

When the current path has no parent, this is a no-op.

Returns: A boolean value indicating whether the path was updated.

◆ SetFile() [2/3]

void FileSpec::SetFile	(	llvm::StringRef	path,
		const llvm::Triple &	triple
	)

Change the file specified with a new path.

Update the contents of this object with a new path. The path will be split up into a directory and filename and stored as uniqued string values for quick comparison and efficient memory usage.

Parameters

[in]	path	A full, partial, or relative path to a file.
[in]	triple	The triple which is used to set the Path style.

◆ SetFile() [3/3]

void FileSpec::SetFile	(	llvm::StringRef	path,
		Style	style
	)

Change the file specified with a new path.

Update the contents of this object with a new path. The path will be split up into a directory and filename and stored as uniqued string values for quick comparison and efficient memory usage.

Parameters

[in]	path	A full, partial, or relative path to a file.
[in]	style	The style for the given path.

◆ SetIsResolved()

void lldb_private::FileSpec::SetIsResolved ( bool is_resolved )

inline

Set if the file path has been resolved or not.

If you know a file path is already resolved and avoided passing a true parameter for any functions that take a "bool resolve_path" parameter, you can set the value manually using this call to make sure we don't try and resolve it later, or try and resolve a path that has already been resolved.

Parameters

[in] is_resolved A boolean value that will replace the current value that indicates if the paths in this object have been resolved.
