Constructor for the FileWaiter.
Most arguments have the same meaning as check_file()
| flist | the file or list of files to wait for. This is simply sent into self.add. |
| min_size | minimum file size |
| min_mtime_age | minimum modification time age, |
| min_atime_age | minimum access time age. |
| min_ctime_age | time since last file status change (see stat(2)) |
| min_fraction | the minimum fraction of the provided files that must match the above requirements in order for FileWaiter.wait to return True. Default is 1.0, which means all of them. |
| def produtil.fileop.FileWaiter.add | ( | self, | |
| flist | |||
| ) |
Adds a file, or iterable that iterates over files, to the list of files to wait for.
If the same filename is received a second time, it is ignored.
| flist | a filename (string) or list of filenames |

| def produtil.fileop.FileWaiter.check | ( | self, | |
| filename, | |||
logger = None |
|||
| ) |
Checks to see if one file meets the requirements set in the constructor.
This default implementation calls check_file. This is in a separate member function so that a subclass can override the file checking method.
| filename | the path to the file to check |
| logger | a logging.Logger for messages |

sleeptime = 20, |

logger = None, |
|||
log_each_file = True |
|||
| ) |
Looks for the requested files.
Will loop, checking over and over up to maxwait seconds, sleeping sleeptime seconds between checks.
| maxwait | maximum seconds to wait |
| sleeptime | sleep time in seconds between checks |
| logger | a logging.Logger for messages |
| log_each_file | log messages about each file checked |
