Class: StreamReader - X-Ref
A stream reader class| createByString($content, $maxMemory = 2097152) X-Ref |
| Creates a stream reader instance by a string value. param: string $content param: int $maxMemory return: StreamReader |
| createByFile($filename) X-Ref |
| Creates a stream reader instance by a filename. param: string $filename return: StreamReader |
| __construct($stream, $closeStream = false) X-Ref |
| StreamReader constructor. param: resource $stream param: bool $closeStream Defines whether to close the stream resource if the instance is destructed or not. |
| __destruct() X-Ref |
| The destructor. |
| cleanUp() X-Ref |
| Closes the file handle. |
| getBufferLength($atOffset = false) X-Ref |
| Returns the byte length of the buffer. param: bool $atOffset return: int |
| getPosition() X-Ref |
| Get the current position in the stream. return: int |
| getBuffer($atOffset = true) X-Ref |
| Returns the current buffer. param: bool $atOffset return: string |
| getByte($position = null) X-Ref |
| Gets a byte at a specific position in the buffer. If the position is invalid the method will return false. If the $position parameter is set to null the value of $this->offset will be used. param: int|null $position return: string|bool |
| readByte($position = null) X-Ref |
| Returns a byte at a specific position, and set the offset to the next byte position. If the position is invalid the method will return false. If the $position parameter is set to null the value of $this->offset will be used. param: int|null $position return: string|bool |
| readBytes($length, $position = null) X-Ref |
| Read bytes from the current or a specific offset position and set the internal pointer to the next byte. If the position is invalid the method will return false. If the $position parameter is set to null the value of $this->offset will be used. param: int $length param: int|null $position return: string|false |
| readLine($length = 1024) X-Ref |
| Read a line from the current position. param: int $length return: string|bool |
| setOffset($offset) X-Ref |
| Set the offset position in the current buffer. param: int $offset |
| getOffset() X-Ref |
| Returns the current offset in the current buffer. return: int |
| addOffset($offset) X-Ref |
| Add an offset to the current offset. param: int $offset |
| ensureContent() X-Ref |
| Make sure that there is at least one character beyond the current offset in the buffer. return: bool |
| getStream() X-Ref |
| Returns the stream. return: resource |
| getTotalLength() X-Ref |
| Gets the total available length. return: int |
| reset($pos = 0, $length = 200) X-Ref |
| Resets the buffer to a position and re-read the buffer with the given length. If the $pos parameter is negative the start buffer position will be the $pos'th position from the end of the file. If the $pos parameter is negative and the absolute value is bigger then the totalLength of the file $pos will set to zero. param: int|null $pos Start position of the new buffer param: int $length Length of the new buffer. Mustn't be negative |
| ensure($pos, $length) X-Ref |
| Ensures bytes in the buffer with a specific length and location in the file. param: int $pos param: int $length |
| increaseLength($minLength = 100) X-Ref |
| Forcefully read more data into the buffer. param: int $minLength return: bool Returns false if the stream reaches the end |
