S )ÚCallbackFileWrapperav
|
Small wrapper around a fp object which will tee everything read into a
|
buffer, and when that file is closed it will execute a callback with the
|
contents of that buffer.
|
|
All attributes are proxied to the underlying file object.
|
|
This class uses members with a double underscore (__) leading prefix so as
|
not to accidentally shadow an attribute.
