Method to re-initialise the class instance
The setup is on the whole controlled by the datatype which
contains e.g. 'x'. This is used to set up the members
self.x and self.y as SpecialVariables (see SpecialVariable
in eoldas_SpecialVariable.py). There are some special attributes
for datatypes starting with 'y'. These are assumed to be
observational data, which means that when they are read, the
data names associated with them are not limited to those in
self.names but rather set to whatever is read in in the data. This
is because the data names for observational data may be terms such
as waveband names etc that need special interpretation. Also,
the default output format for observational data is
different to that of other data.
The elements self.state is a SpecialVariables which means
that they can be assigned various data types (see SpecialVariables)
and loaded accordingly (e.g. if a filename is specified, this is
read in to the data structure. The SpecialVariables contain 'hidden'
datasets, which here are mainly the 'control' and 'location'
information. A SpecialVariable has two internal structures: `data`
and `name`. The former is used to store data values (e.g. the
state values) and the latter to store associated metadata.
For example, `control` is passed here e.g. as [`mask`,`vza`] and this
gives the metadata that are stored in `name`. The actual values
of the control data are stored in the `data` section. For
location, we might be passed [`time`,`row`,`col`], so this is set
in names.location, and the data.location contains the values
of the location at each of these elements. For the actual state
dataset, this is stored according to its name, so for `x` the values
are stored in data.x and the associated data names in name.x.
State datasets must represent at least the mean and standard deviation
of a state for them to be of value in EOLDAS. TThe mean is accessed
as e.g. self.state for the state dataset.
The sd is accessed can be accessed as self._state.sd if it
has been set. This reference can also be used to directly set
data associated with a SpecialVariable, e.g.
self.Data.control = np.zeros([2,3])
to represent 2 samples with 3 control variables. You can access name
information similarly with
print self.Name.control
but this will generate a KeyError if the term has not been set. You
can check it exists with:
key = 'control'
if key in self.Name:
this = (self.Data[key],self.Name[key])
To get e.g. a dictionary representation of a SpecialVariable
you can use eg:
self.Name.to_dict()
to get the name dictionary, or
thisdict = self._state.to_dict()
to get the full representation, which then contains 'data' and
'name' as well as some other information stored in the
SpecialVariable.
You can similarly load them using e.g.
self.Data.update(
ParamStorage().from_dict(thisdict['data'])
combine=True)
