qiskit.opflow.state_fns.StateFn.traverse¶
- StateFn.traverse(convert_fn, coeff=None)[source]¶
Apply the convert_fn to the internal primitive if the primitive is an Operator (as in the case of
OperatorStateFn). Otherwise do nothing. Used by converters.- Parameters
convert_fn (Callable) -- The function to apply to the internal OperatorBase.
coeff (Optional[Union[complex, ParameterExpression]]) -- A coefficient to multiply by after applying convert_fn. If it is None, self.coeff is used instead.
- Returns
The converted StateFn.
