Classes¶

DataPoint ¶

DataPoint(u, uc)

Wrapper around arc.datapoint_from_url() which does not clean up DataPoints when python objects are destroyed, leading to connection leaking when used with gridftp. This class should be used instead of arc.datapoint_from_url(). It can be called like dp = DataPoint('gsiftp://...', uc); dp.h.Stat() where uc is an arc.UserConfig object.

Default ¶

Default(protocol_attr, rse_settings, logger=None)

Implementing access to RSEs using ARC client.

Set up UserConfig object.
