Composition
Conditions describing the composition of a material.
Classes
-
class pyhmsa.spec.condition.composition.CompositionElemental(unit, values=None, **kwargs)
Defines the composition of a material in terms of its constituent
elements.
The composition is a dict where the keys are atomic numbers
and the values the amounts of an element.
Parameters: | unit – unit in which the composition is defined (required) |
-
CLASS = 'Elemental'
-
TEMPLATE = 'Composition'
-
clear() → None. Remove all items from D.
-
get(k[, d]) → D[k] if k in D, else d. d defaults to None.
-
get_unit(instance)
-
items() → list of D's (key, value) pairs, as 2-tuples
-
iteritems() → an iterator over the (key, value) items of D
-
iterkeys() → an iterator over the keys of D
-
itervalues() → an iterator over the values of D
-
keys() → list of D's keys
-
pop(k[, d]) → v, remove specified key and return the corresponding value.
If key is not found, d is returned if given, otherwise KeyError is raised.
-
popitem() → (k, v), remove and return some (key, value) pair
as a 2-tuple; but raise KeyError if D is empty.
-
set_unit(instance, value)
-
setdefault(k[, d]) → D.get(k,d), also set D[k]=d if k not in D
-
to_wt()
Returns a CompositionElemental with unit of wt%.
-
unit
unit in which the composition is defined
-
update([E, ]**F) → None. Update D from mapping/iterable E and F.
If E present and has a .keys() method, does: for k in E: D[k] = E[k]
If E present and lacks .keys() method, does: for (k, v) in E: D[k] = v
In either case, this is followed by: for k, v in F.items(): D[k] = v
-
values() → list of D's values
