SyncdDevice

```
public interface SyncdDevice
```
SyncdDevice is for a device that wants to be in sync with the event loop. If there is sync'd device registered with the event loop manager then the event loop manager will run the event loop in this manner:
1. wait until all sync'd device have returned from blockUtilReady()
2. run EventLoop.loop()
3. call startBlockingWork() on all sync'd device
Sync'd devices need to register themselves with the event loop manager

Method Summary

Methods
Modifier and Type	Method and Description
`void`	`blockUntilReady()` This method should block until it is ready for the event loop to run, Once this method has returned, subsequent calls should return immediately until startBlockingWork() has been called.
`RobotUsbModule`	`getOwner()` Retrieves the owning module of this sync'd device.
`boolean`	`hasShutdownAbnormally()` Has this device shutdown abnormally? Note that even if this method returns true that a close() will still be necessary to fully clean up associated resources.
`void`	`setOwner(RobotUsbModule owner)` Records the owning module of this sync'd device.
`void`	`startBlockingWork()` This method will be called to let the sync'd device know that it's ok to enter a blocking state.

- Method Detail
  - blockUntilReady
```
void blockUntilReady()
                     throws RobotCoreException,
                            java.lang.InterruptedException
```
    This method should block until it is ready for the event loop to run, Once this method has returned, subsequent calls should return immediately until startBlockingWork() has been called.
    
    Throws:
    
    java.lang.InterruptedException
    
    RobotCoreException
  - startBlockingWork
```
void startBlockingWork()
```
    This method will be called to let the sync'd device know that it's ok to enter a blocking state.
    Before this method returns, the sync'd device should put blockUntilReady() into a blocking state. blockUntilReady() should remain in a blocking state until the device is ready for the event loop to run. Once blockUntilReady() returns, it should not block again until startBlockingWork() has been called.
  - hasShutdownAbnormally
```
boolean hasShutdownAbnormally()
```
    Has this device shutdown abnormally? Note that even if this method returns true that a close() will still be necessary to fully clean up associated resources.
    
    Returns:
    whether the device has experienced an abnormal shutdown
  - setOwner
```
void setOwner(RobotUsbModule owner)
```
    Records the owning module of this sync'd device. The owner of the device is the party that is responsible for the device's lifetime management, and thus who should be involved if the device experiences problems and needs to be shutdown or restarted.

    getOwner()
  - getOwner
```
RobotUsbModule getOwner()
```
    Retrieves the owning module of this sync'd device.
    
    Returns:
    the RobotUsbModule which is the owner of this device
    See Also:
    setOwner(RobotUsbModule)
