Detailed Description

Path with file status class.

This class is identical to Path class except it allows you to obtain the file status of the Path as well. The reason for the distinction is one of efficiency. First, the file status requires additional space and the space is incorporated directly into PathWithStatus without an additional malloc. Second, obtaining status information is an expensive operation on most operating systems so we want to be careful and explicity about where we allow this operation in LLVM.

)

[inline]

Path constructor.

This constructor allows construction from a Path object

Definition at line 608 of file Path.h.

llvm::sys::PathWithStatus::PathWithStatus

(

const std::string &

p

)

[inline, explicit]

Construct a Path from a string.

This constructor will accept a std::string as a path. No checking is done on this path to determine if it is valid. To determine validity of the path, use the isValid method.

Parameters:

p	The path to assign.

Definition at line 615 of file Path.h.

llvm::sys::PathWithStatus::PathWithStatus	(	const char *	StrStart,
		unsigned	StrLen
	)			[inline, explicit]

Construct a Path from a string.

This constructor will accept a character range as a path. No checking is done on this path to determine if it is valid. To determine validity of the path, use the isValid method.

Parameters:

StrStart	Pointer to the first character of the path
StrLen	Length of the path.

PathWithStatus& llvm::sys::PathWithStatus::operator=

(

const Path &

that

)

[inline]

Assignment Operator.

Makes a copy of that to this.

Returns:

this

Reimplemented from llvm::sys::Path.

Definition at line 641 of file Path.h.

const FileStatus* llvm::sys::PathWithStatus::getFileStatus	(	bool	forceUpdate = false,
		std::string *	Error = 0
	)			const

Get file status.

This function returns status information about the file. The type of path (file or directory) is updated to reflect the actual contents of the file system.

Returns:

0 on failure, with Error explaining why (if non-zero)

a pointer to a FileStatus structure on success.

Parameters:

forceUpdate	Force an update from the file system
Error	Optional place to return an error msg.
