abstract LegacyBaseOperator.__mul__(other)
Overload *
chop
abstract LegacyBaseOperator.chop(threshold, copy=False)
construct_evaluation_circuit
abstract LegacyBaseOperator.construct_evaluation_circuit(wave_function, statevector_mode, **kwargs)
Build circuits to compute the expectation w.r.t the wavefunction.
evaluate_with_result
abstract LegacyBaseOperator.evaluate_with_result(result, statevector_mode, **kwargs)
Consume the result from the quantum computer to build the expectation, will be only used along with the construct_evaluation_circuit() method.

Time evolution, exp^(-jt H).
is_empty
abstract LegacyBaseOperator.is_empty()
Check Operator is empty or not
print_details
abstract LegacyBaseOperator.print_details()
print details
to_opflow
abstract LegacyBaseOperator.to_opflow()
Convert to new Operator format.
