public DEVICE_TYPE get(java.lang.String deviceName)
```
  - put
```
public void put(java.lang.String deviceName,
       DEVICE_TYPE device)
```
    Registers a new device in this DeviceMapping under the indicated name. Any existing device with this name in this DeviceMapping is removed. The new device is also added to the overall collection in the overall map itself. Note that this method is normally called only by code in the SDK itself, not by user code.
    
    Parameters:
    deviceName - the name by which the new device is to be known (case sensitive)
    device - the new device to be named
    See Also:
    HardwareMap.put(String, HardwareDevice)
  - remove
```
public boolean remove(java.lang.String deviceName)
```
    Removes the device with the indicated name (if any) from this DeviceMapping. The device is also removed under that name in the overall map itself. Note that this method is normally called only by code in the SDK itself, not by user code.
    
    Parameters:
    deviceName - the name of the device to remove.
    
    Returns:
    whether any modifications were made to this DeviceMapping

    HardwareMap.remove(String, HardwareDevice)
  - iterator
```
public java.util.Iterator<DEVICE_TYPE> iterator()
```
    Returns an iterator over all the devices in this DeviceMapping.
    
    Specified by:
    
    iterator in interface java.lang.Iterable<DEVICE_TYPE extends HardwareDevice>
    
    Returns:
    an iterator over all the devices in this DeviceMapping.
  - entrySet
```
public java.util.Set<java.util.Map.Entry<java.lang.String,DEVICE_TYPE>> entrySet()
```
    Returns a collection of all the (name, device) pairs in this DeviceMapping.
    
    Returns:
    a collection of all the (name, device) pairs in this DeviceMapping.
  - size
```
public int size()
```
    Returns the number of devices currently in this DeviceMapping
    
    Returns:
