copy(**kw__None)

return self; self is a Sentinel so there is only 1 instance.

static deserialize(serial)

creates an XarrayIoSerializable object from a serialized representation.

serial: dict or str

str –> convert to dict via ast.literal_eval.

dict must contain ‘typename’ key.

The output here will be an instance of XarrayIoSerializable.SERIAL_TYPES[typename]

equal_except_i(v)

returns whether self == v (another DimensionValue), ignoring i.

equal if v is an instance of type(self) and

all kw from both self._kw_eq and v._kw_eq have the same values.

(any kw missing attrs will be treated as UNSET.)

For DimensionValue: self.s==v.s and self.i==v.i. Subclasses may add more.

classmethod from_dict(d)

return cls from dict d.

If ‘d’ contains ‘typename’, result is like cls.deserialize(d) instead,

however, first require that result is an instance of cls (or subclass of cls).

E.g. Fluid.from_dict(dict(typename=’EppicDist’, …)) returns EppicDist,

but Snap.from_dict(dict(typename=’EppicDist’, …)) crashes with InputError.

Subclasses wishing to alter deserialize behavior will probably override this method instead.

getter(dlist)

get the value from dlist specified by self.

(Here, just returns self, the SpecialDimensionValue)

is_charged()

tells whether self is a charged fluid. i.e. self.q != 0.

if self.q is None, returns None instead of bool.

is_electron()

tells whether self is an electron. i.e. self.q < 0.

if self.q is None, returns None instead of bool.

is_ion()

tells whether self is an ion. i.e. self.q > 0.

if self.q is None, returns None instead of bool.

is_neutral()

tells whether self is a neutral fluid. i.e. self.q == 0.

if self.q is None, returns None instead of bool.

lookup_dict()

returns dict for looking up self within a DimensionValueList, given int, str, or self.

(used by DimensionValueList.lookup_dict)

name = None

static register_type(cls_to_register, _serial_typename=None)

register cls_to_register as a serializable subclass of XarrayIoSerializable.

_serial_typename: str or None

name to use for serialization. if None, use cls_to_register.__name__.

property s

alias to name

serialize()

return dict of info about self, including ‘typename’ key.

to_dict()

return dictionary of info about self. Attribute values for keys in self._kw_def.

e.g. if _kw_def={‘s’, ‘i’}: result = {‘s’: self.s, ‘i’: self.i}

with_i(i)

return copy of self with i=i, or self if self.i==i already.
