- Method Detail
  - getKey
```
String getKey()
```
    Get the unique device identifier for this device
    
    Returns:
    
    unique device identifier
  - isOpen
```
boolean isOpen()
```
    Check if this device is open or closed
    
    Returns:
    
    true if this device is open
  - isChild
```
boolean isChild()
```
    Check if this is a child / wrapped device. Child devices are assumed to be closed by the parent device. Key example is a software PWM output device that uses a digital output device.
    
    Returns:
    
    true if this a child / wrapped device
  - setChild
```
void setChild(boolean child)
```
