spunQ_File::lock ( $ timeout = 0 ) [inherited]

Tries to lock the file.

Will try to acquire an exclusive write lock to the file. Note that this function will block (as if the $timeout parameter was NULL) regardless of the function parameter on a windows machine due to the implementation of flock().

See also:: http://php.net/flock

Parameters:

$timeout

Amount of seconds the function should block until the file is locked. Setting this to NULL will block indefinitely (until max_execution_time runs out). The default value of 0 will not block at all.

Returns:: boolean Whether the file was locked

Definition at line 101 of file File.class.php.

spunQ_File::moveTo	(	$	folder,
		$	overwrite,
		$	newName = `NULL`
	)			`[inherited]`

Moves this file into another directory (and optionally renames it).

Parameters:

	$folder	the folder to move to. Either a spunQ_IFolder or a string.
	$overwrite	Whether the destination file should be overwritten.
	$newName	The file will be renamed, too if this is set.

Returns:: spunQ_IFile $this

Implements spunQ_IFile.

Definition at line 219 of file File.class.php.

static spunQ_FileNode::pathIsAbsolute ( $ filePath ) [static, inherited]

Tests if a givebn file path is absolute or relative.

Parameters:

$filePath

The file path - a string.

Returns:: boolean

Definition at line 14 of file FileNode.class.php.

static spunQ_FileNode::prettifyPath ( $ path ) [static, inherited]

Makes transformations to a path string to make it more readable.

Removes references to current and upper directories (/foo/.. or foo/.), for example. Assumes that the path has a slash as delimiter. if you want to use this function on a windows path, make sure to replace backslashes by forward slashes beforehand.

Parameters:

$path

The path string to transform.

Returns:: string

Definition at line 34 of file FileNode.class.php.

spunQ_File::rename	(	$	newName,
		$	overwrite
	)			`[inherited]`

Renames the file, but keeps it in the same folder.

Use moveTo() if you want to rename and move.

Parameters:

	$newName	The new name of the file.
	$overwrite	Whether the destination file should be overwritten.

Returns:: spunQ_IFile $this

Implements spunQ_IFile.

Definition at line 195 of file File.class.php.

spunQ_FileNode::residesIn ( spunQ_IFolder $ folder ) [inherited]

Checks whether this file is in given folder or one of its subfolders.

Parameters:

$folder

The folder to test against.

Returns:: bool

Implements spunQ_IFileNode.

Definition at line 85 of file FileNode.class.php.

spunQ_File::unlock ( ) [inherited]

Unlocks the previously locked file.

Returns:: spunQ_File $this

Definition at line 137 of file File.class.php.

Member Data Documentation

spunQ_File::$filePointer = NULL [protected, inherited]

File pointer acquired through call to fopen().

The file pointer is current only used when locking the file through flock()! I repeat: it is not used for reading/writing data, merely for locking the file.

Type:: resource

Definition at line 86 of file File.class.php.

spunQ_FileNode::$path [protected, inherited]

The path pointing to the node.

string

Definition at line 64 of file FileNode.class.php.
