Extra annotations

class PropertyTransformer

Parent class for annotations that transform object attributes.

This class is not intended to be used by itself, but instead inherited and implemented. Right now, this class is a trivial implementation, i.e. passthrough of getter and setter.

When the :method getter: is implemented, it will be used to transform the data during getattr operations.

Similarly, the :method setter: is used to transform the value during setattr operations.

getter(value)

Transform the value during a getattr operation.

setter(value)

Transform the value during a setattr operation.

class LocalOnly

Annotation to specify attributes that must no be persisted.

Example:

class ComplexAlgorithm(DataClayObject):
    primes_cache: Annotated[list[int], LocalOnly]
