An object that explicitly specifies how to act on simulator states.
cirq.SupportsActOn(
*args, **kwargs
)
Methods
_act_on_
_act_on_(
sim_state: 'cirq.SimulationStateBase'
) -> Union[NotImplementedType, bool]
Applies an action to the given argument, if it is a supported type.
For example, unitary operations can implement an _act_on_ method that
checks if isinstance(sim_state, cirq.StateVectorSimulationState) and,
if so, apply their unitary effect to the state vector.
The global cirq.act_on method looks for whether or not the given
argument has this value, before attempting any fallback strategies
specified by the argument being acted on.
This should only be implemented on Operation subclasses. Others such
as gates should use SupportsActOnQubits.
| Args | |
|---|---|
sim_state
|
An object of unspecified type. The method must check if this object is of a recognized type and act on it if so. |
| Returns | |
|---|---|
True
|
The receiving object (self) acted on the argument.
|
NotImplemented
|
The receiving object did not act on the argument.
All other return values are considered to be errors. |
