The class result_base is very similar to
|
|
wpylib.params.params_flat.Parameters ,
|
|
except that it does not contain multiple dict-like objects, thus is
|
|
much simpler.

'''Structure to represent metadata or structured result.
|
|
No particular structure is assumed.
|

Results are fetchable by either X.member or X['member'] syntax, and these

results are typically meant to be read-only.

* Note: dict method names are left intact.
|
|
Please be aware when programming this thing!
|
|
* Additional possible field names set by this class:
|
|
- filename_
|
|
- absfilename_ -- full file name including absolute directory path.
|
|
* __setattr__ is not set.
|
|
Result-related attributes are supposed to be read-only.
|
|
As a consequence, adding metadata or result *must* be done in the
|
|
dict way, e.g.
|
|
X['nblocks'] = 32
|
|
instead of
|
|
X.nblocks = 32.
