PHP Класс Neos\Flow\ResourceManagement\Streams\StreamWrapperAdapter

The resource manager will register configured stream wrappers with this class, enabling the use of Flow goodies like DI in those stream wrappers. Instances of this class are created by PHP itself and therefore are unknown to Flow's object registry.

stream_eof() публичный Метод

This method is called in response to feof().
public stream_eof ( ) : boolean
Результат boolean Should return TRUE if the read/write position is at the end of the stream and if no more data is available to be read, or FALSE otherwise.

stream_flush() публичный Метод

This method is called in response to fflush(). If you have cached data in your stream but not yet stored it into the underlying storage, you should do so now. Note: If not implemented, FALSE is assumed as the return value.
public stream_flush ( ) : boolean
Результат boolean Should return TRUE if the cached data was successfully stored (or if there was no data to store), or FALSE if the data could not be stored.

stream_lock() публичный Метод

This method is called in response to flock(), when file_put_contents() (when flags contains LOCK_EX), stream_set_blocking() and when closing the stream (LOCK_UN). $operation is one of the following: LOCK_SH to acquire a shared lock (reader). LOCK_EX to acquire an exclusive lock (writer). LOCK_UN to release a lock (shared or exclusive). LOCK_NB if you don't want flock() to block while locking.
public stream_lock ( integer $operation ) : boolean
$operation integer One of the LOCK_* constants
Результат boolean TRUE on success or FALSE on failure.

stream_open() публичный Метод

This method is called immediately after the wrapper is initialized (f.e. by fopen() and file_get_contents()). $options can hold one of the following values OR'd together: STREAM_USE_PATH If path is relative, search for the resource using the include_path. STREAM_REPORT_ERRORS If this flag is set, you are responsible for raising errors using trigger_error() during opening of the stream. If this flag is not set, you should not raise any errors.
public stream_open ( string $path, string $mode, integer $options, &$opened_path ) : boolean
$path string Specifies the URL that was passed to the original function.
$mode string The mode used to open the file, as detailed for fopen().
$options integer Holds additional flags set by the streams API.
Результат boolean TRUE on success or FALSE on failure.

stream_read() публичный Метод

This method is called in response to fread() and fgets(). Note: Remember to update the read/write position of the stream (by the number of bytes that were successfully read).
public stream_read ( integer $count ) : string
$count integer How many bytes of data from the current position should be returned.
Результат string If there are less than count bytes available, return as many as are available. If no more data is available, return either FALSE or an empty string.

stream_seek() публичный Метод

This method is called in response to fseek(). The read/write position of the stream should be updated according to the offset and whence . $whence can one of: SEEK_SET - Set position equal to offset bytes. SEEK_CUR - Set position to current location plus offset. SEEK_END - Set position to end-of-file plus offset.
public stream_seek ( integer $offset, integer $whence = SEEK_SET ) : boolean
$offset integer The stream offset to seek to.
$whence integer
Результат boolean TRUE on success or FALSE on failure.

stream_set_option() публичный Метод

This method is called to set options on the stream. $option can be one of: STREAM_OPTION_BLOCKING (The method was called in response to stream_set_blocking()) STREAM_OPTION_READ_TIMEOUT (The method was called in response to stream_set_timeout()) STREAM_OPTION_WRITE_BUFFER (The method was called in response to stream_set_write_buffer()) If $option is ... then $arg1 is set to: STREAM_OPTION_BLOCKING: requested blocking mode (1 meaning block 0 not blocking). STREAM_OPTION_READ_TIMEOUT: the timeout in seconds. STREAM_OPTION_WRITE_BUFFER: buffer mode (STREAM_BUFFER_NONE or STREAM_BUFFER_FULL). If $option is ... then $arg2 is set to: STREAM_OPTION_BLOCKING: This option is not set. STREAM_OPTION_READ_TIMEOUT: the timeout in microseconds. STREAM_OPTION_WRITE_BUFFER: the requested buffer size.
public stream_set_option ( integer $option, integer $arg1, integer $arg2 ) : boolean
$option integer
$arg1 integer
$arg2 integer
Результат boolean TRUE on success or FALSE on failure. If option is not implemented, FALSE should be returned.

stream_stat() публичный Метод

This method is called in response to fstat().
public stream_stat ( ) : array
Результат array See http://php.net/stat

stream_tell() публичный Метод

This method is called in response to ftell().
public stream_tell ( ) : integer
Результат integer Should return the current position of the stream.

stream_write() публичный Метод

This method is called in response to fwrite(). If there is not enough room in the underlying stream, store as much as possible. Note: Remember to update the current position of the stream by number of bytes that were successfully written.
public stream_write ( string $data ) : integer
$data string Should be stored into the underlying stream.
Результат integer Should return the number of bytes that were successfully stored, or 0 if none could be stored.

url_stat() публичный Метод

This method is called in response to all stat() related functions. $flags can hold one or more of the following values OR'd together: STREAM_URL_STAT_LINK For resources with the ability to link to other resource (such as an HTTP Location: forward, or a filesystem symlink). This flag specified that only information about the link itself should be returned, not the resource pointed to by the link. This flag is set in response to calls to lstat(), is_link(), or filetype(). STREAM_URL_STAT_QUIET If this flag is set, your wrapper should not raise any errors. If this flag is not set, you are responsible for reporting errors using the trigger_error() function during stating of the path.
public url_stat ( string $path, integer $flags ) : array
$path string The file path or URL to stat. Note that in the case of a URL, it must be a :// delimited URL. Other URL forms are not supported.
$flags integer Holds additional flags set by the streams API.
Результат array Should return as many elements as stat() does. Unknown or unavailable values should be set to a rational value (usually 0).
