Class Declaration

namespace aes70::controller
{
  class OcaPolarity : public OcaActuator

    OcaPolarity(const OcaPolarity &o);

    // Control Methods
    // Calls GetState and calls on_result or on_failure
    void GetState(auto on_result, failure_callback on_failure);
    // Calls SetState and calls on_result or on_failure
    void SetState(OcaPolarityState state, auto on_result, failure_callback on_failure);
    // Calls SetState and does not wait for the response
    void SetState(OcaPolarityState state);

    // Observing Properties
    subscription observeState(auto callback, failure_callback on_failure);

    // Property Changed Subscriptions
    subscription OnStateChanged(auto callback, failure_callback on_failure);
  };
}

Methods

GetState

void GetState(auto on_result, failure_callback on_failure)

Calls the method GetState in the remote device.

Parameters:

• auto on_result: A callable (e.g. a lambda) with the following arguments:
  • OcaPolarityState state
• failure_callback on_failure: A callback which is called on error.

SetState

void SetState(OcaPolarityState state, auto on_result, failure_callback on_failure)

Calls the method SetState in the remote device. If no result and error callback is specified, the method will be called without requesting a response.

Parameters:

• OcaPolarityState state
• auto on_result: A callable (e.g. a lambda) with 0 arguments.
• failure_callback on_failure: A callback which is called on error.

observeState

subscription observeState(auto callback, failure_callback on_failure)

Fetches the remote property State and subscribes for modifications. The callback is called with the initial values of State and whenever it changes.

Parameters:

• auto callback: A callable (e.g. a lambda) with one argument: OcaPolarityState State
• failure_callback on_failure: A callback which is called on error.

OnStateChanged

subscription OnStateChanged(auto callback, failure_callback on_failure)

Parameters

• auto callback: A callable (e.g. a lambda) with one argument: OcaPolarityState State
• failure_callback on_failure: A callback which is called on error.
