Deprecated since version 0.7.3: Use QRules and AmpForm instead

import expertsystem.amplitude.dynamics.builder

Build lineshape with correct variable names and values.

class ResonanceDynamicsBuilder(*args, **kwargs)[source]

Bases: Protocol

Protocol that is used by set_dynamics.

Follow this Protocol when defining a builder function that is to be used by set_dynamics. For an example, see the source code create_relativistic_breit_wigner, which creates a relativistic_breit_wigner.

verify_signature(builder: Callable) → None[source]

Check signature of a builder function dynamically.

Dynamically check whether a builder has the same signature as ResonanceDynamicsBuilder. This function is needed because typing.runtime_checkable does only checks members and methods, not the signature of those methods.
