  - FindPowerSupply
```
public static YPowerSupply FindPowerSupply(String func)
```
    Retrieves a regulated power supply for a given identifier. The identifier can be specified using several formats:
    - FunctionLogicalName
    - ModuleSerialNumber.FunctionIdentifier
    - ModuleSerialNumber.FunctionLogicalName
    - ModuleLogicalName.FunctionIdentifier
    - ModuleLogicalName.FunctionLogicalName
    This function does not require that the regulated power supply is online at the time it is invoked. The returned object is nevertheless valid. Use the method YPowerSupply.isOnline() to test if the regulated power supply is indeed online at a given time. In case of ambiguity when looking for a regulated power supply by logical name, no error is notified: the first instance found is returned. The search is performed first by hardware name, then by logical name. If a call to this object's is_online() method returns FALSE although you are certain that the matching device is plugged, make sure that you did call registerHub() at application initialization time.
    Parameters:
    
    func - : a string that uniquely characterizes the regulated power supply, for instance MyDevice.powerSupply.
    
    Returns:
    
    a YPowerSupply object allowing you to drive the regulated power supply.
  - FindPowerSupplyInContext
```
public static YPowerSupply FindPowerSupplyInContext(YAPIContext yctx,
                                                    String func)
```
    Retrieves a regulated power supply for a given identifier in a YAPI context. The identifier can be specified using several formats:
    - FunctionLogicalName
    - ModuleSerialNumber.FunctionIdentifier
    - ModuleSerialNumber.FunctionLogicalName
    - ModuleLogicalName.FunctionIdentifier
    - ModuleLogicalName.FunctionLogicalName
    This function does not require that the regulated power supply is online at the time it is invoked. The returned object is nevertheless valid. Use the method YPowerSupply.isOnline() to test if the regulated power supply is indeed online at a given time. In case of ambiguity when looking for a regulated power supply by logical name, no error is notified: the first instance found is returned. The search is performed first by hardware name, then by logical name.
    Parameters:
    
    yctx - : a YAPI context
    
    func - : a string that uniquely characterizes the regulated power supply, for instance MyDevice.powerSupply.
    
    Returns:
    
    a YPowerSupply object allowing you to drive the regulated power supply.
  - registerValueCallback
```
public int registerValueCallback(YPowerSupply.UpdateCallback callback)
```
    Registers the callback function that is invoked on every change of advertised value. The callback is invoked only during the execution of ySleep or yHandleEvents. This provides control over the time when the callback is triggered. For good responsiveness, remember to call one of these two functions periodically. To unregister a callback, pass a null pointer as argument.
    
    Parameters:
    
    callback - : the callback function to call, or a null pointer. The callback function should take two arguments: the function object of which the value has changed, and the character string describing the new advertised value.
  - _invokeValueCallback
```
public int _invokeValueCallback(String value)
```
    Overrides:
    
    _invokeValueCallback in class YFunction
  - voltageMove
```
public int voltageMove(double V_target,
                       int ms_duration)
                throws YAPI_Exception
```
    Performs a smooth transition of output voltage. Any explicit voltage change cancels any ongoing transition process.
    
    Parameters:
    
    V_target - : new output voltage value at the end of the transition (floating-point number, representing the end voltage in V)
    
    ms_duration - : total duration of the transition, in milliseconds
    
    Returns:
    
    YAPI.SUCCESS when the call succeeds.
    
    Throws:
    
    YAPI_Exception
  - nextPowerSupply
```
public YPowerSupply nextPowerSupply()
```
    Continues the enumeration of regulated power supplies started using yFirstPowerSupply(). Caution: You can't make any assumption about the returned regulated power supplies order. If you want to find a specific a regulated power supply, use PowerSupply.findPowerSupply() and a hardwareID or a logical name.
    
    Returns:
    
    a pointer to a YPowerSupply object, corresponding to a regulated power supply currently online, or a null pointer if there are no more regulated power supplies to enumerate.
  - FirstPowerSupply
```
public static YPowerSupply FirstPowerSupply()
```
    Starts the enumeration of regulated power supplies currently accessible. Use the method YPowerSupply.nextPowerSupply() to iterate on next regulated power supplies.
    
    Returns:
    
    a pointer to a YPowerSupply object, corresponding to the first regulated power supply currently online, or a null pointer if there are none.
  - FirstPowerSupplyInContext
```
public static YPowerSupply FirstPowerSupplyInContext(YAPIContext yctx)
```
    Starts the enumeration of regulated power supplies currently accessible. Use the method YPowerSupply.nextPowerSupply() to iterate on next regulated power supplies.
    
    Parameters:
    
    yctx - : a YAPI context.
    
    Returns:
    
    a pointer to a YPowerSupply object, corresponding to the first regulated power supply currently online, or a null pointer if there are none.
