Details

at line 18
static int getType()

Returns the type of stream wrapper.

Return Value

int

at line 39
string getDirectoryPath()

Gets the path that the wrapper is responsible for.

Return Value

string

String specifying the path.

in LocalStream at line 60
setUri(string $uri)

Sets the absolute stream resource URI.

This allows you to set the URI. Generally is only called by the factory method.

Parameters

string $uri

A string containing the URI that should be used for this instance.

in LocalStream at line 67
string getUri()

Returns the stream resource URI.

Return Value

string

Returns the current URI of the instance.

in LocalStream at line 87
protected string|bool getTarget(string $uri = NULL)

Returns the local writable target of the resource within the stream.

This function should be used in place of calls to realpath() or similar functions when attempting to determine the location of a file. While functions like realpath() may return the location of a read-only file, this method may return a URI or path suitable for writing that is completely separate from the URI used for reading.

Parameters

string $uri

Optional URI.

Return Value

string|bool

Returns a string representing a location suitable for writing of a file, or FALSE if unable to write to the file such as with read-only streams.

in LocalStream at line 101
string realpath()

Returns canonical, absolute path of the resource.

Implementation placeholder. PHP's realpath() does not support stream wrappers. We provide this as a default so that individual wrappers may implement their own solutions.

Return Value

string

Returns a string with absolute pathname on success (implemented by core wrappers), or FALSE on failure or if the registered wrapper does not provide an implementation.

in LocalStream at line 120
protected string|bool getLocalPath(string $uri = NULL)

Returns the canonical absolute path of the URI, if possible.

Parameters

string $uri

(optional) The stream wrapper URI to be converted to a canonical absolute path. This may point to a directory or another type of file.

Return Value

string|bool

If $uri is not set, returns the canonical absolute path of the URI previously set by the Drupal\Core\StreamWrapper\StreamWrapperInterface::setUri() function. If $uri is set and valid for this class, returns its canonical absolute path, as determined by the realpath() function. If $uri is set but not valid, returns FALSE.

in LocalStream at line 163
bool stream_open(string $uri, $mode, $options, $opened_path)

Support for fopen(), file_get_contents(), file_put_contents() etc.

Parameters

string $uri

A string containing the URI to the file to open.
