Methods

TensorComponents.map()
Generic map for dataclass instances.
f should be a function taking two parameters: the name of the dataclass member and its value, and it should return a tuple containing the same quantities. If a member is not to be transformed, f should just return a tuple of the input member name and value, unchanged. Both names and values can be transformed, with the semantics following those of dataclasses.replace.
In Salvus we primarily treat dataclasses as containers offering semantics similar to typed dictionaries. Deriving from this protocol allows any relevant dataclass to additionally be treated functorially. This allows for the generic un- and re-wrapping of value held in dataclasses, and essentially replaces the following imperative code:
@dataclass
class A:
    member: int

# Before
my_a = A(member=1)
my_a_new = dataclasses.replace(my_a, member=2 * my_a.member)

# After
my_a_new = A(val=1).map(lambda key, val: (key, 2 * val))
As with many functional patterns, the perceived benefits for simple demonstrative purposes is minimal. The scalability of this pattern becomes apparent, however, when parsing deeply nested abstractions, as the transformation logic can be factored out into independent functions. This is used extensively, for example, in the realization logic of the layered mesher, where generic materials can have generic parameters, etc.
SIGNATURE
def map(
    self, f: typing.Callable[[str, typing.Any], tuple[str, typing.Any]]
) -> typing.Self: ...
ARGUMENTS
Required
f
Type:typing.Callable[[str, typing.Any], tuple[str, typing.Any]]
Description:
The function to map over the dataclass.
TensorComponents.map_realized_parameters()
Apply functions to each parameter individually, distinguishing _pd.
Useful when one wants to transform each parameter type separately. For instance, transformations of discrete parameters often require more associated logic than their constant equivalents. This function abstracts away the boilerplate of check for each parameter type, and subsequently transforming it with some function, as well as ensuring that the parameters are indeed of the correct realized type.
The signatures of each transformation function should take the parameter's name and value as two distinct inputs, and return the (potentially modified) parameter value.
