"""Returns a copy of this operation with an updated ParamResolver.
Any existing parameter mappings will have their values updated given
the provided mapping, and any new parameters will be added to the
ParamResolver.
Note that any resulting parameter mappings with no corresponding
parameter in the base circuit will be omitted.
Args:
param_values: A map or ParamResolver able to convert old param
values to new param values. This map will be composed with any
existing ParamResolver via single-step resolution.
recursive: If True, resolves parameter values recursively over the
resolver; otherwise performs a single resolution step. This
behavior applies only to the passed-in mapping, for the current
application. Existing parameters are never resolved recursively
because a->b and b->a needs to be a valid mapping.
Returns:
A copy of this operation with its ParamResolver updated as specified
by param_values.
