class swiftly.filelikeiter.FileLikeIter(iterable)

Bases: object

Wraps an iterable to behave as a file-like object.

Taken from work I did for OpenStack Swift swift.common.utils.FileLikeIter, Copyright (c) 2010-2012 OpenStack Foundation.

close() → None or (perhaps) an integer. Close the file.

Sets data attribute .closed to True. A closed file cannot be used for further I/O operations. close() may be called more than once without error. Some kinds of file objects (for example, opened by popen()) may return an exit status upon closing.

next() → the next value, or raise StopIteration

read([size]) → read at most size bytes, returned as a string.

If the size argument is negative or omitted, read until EOF is reached. Notice that when in non-blocking mode, less data than what was requested may be returned, even if no size parameter was given.

readline([size]) → next line from the file, as a string.

Retain newline. A non-negative size argument limits the maximum number of bytes to return (an incomplete line may be returned then). Return an empty string at EOF.

readlines([size]) → list of strings, each a line from the file.

Call readline() repeatedly and return a list of the lines so read. The optional size argument, if given, is an approximate bound on the total number of bytes in the lines returned.
