Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`long`	`getFirstFrameTimestamp()`	Returns the timestamp of the first frame ready to be dispatched or `TimeEncoding.INVALID_INSTANT` if there is no frame.
`TcTransferFrame`	`getFrame()`	Retrieves the next frame in the Virtual Channel, or returns null if there is no frame available at the moment.
`VcUplinkManagedParameters`	`getParameters()`	return the virtual channel parameters
`void`	`setDataAvailableSemaphore(Semaphore dataAvailableSemaphore)`	The semaphore will be used by the virtual channel to signal to `MasterChannelFrameMultiplexer` that data is available to be uplinked

- Method Detail
  - getFrame
```
TcTransferFrame getFrame()
```
    Retrieves the next frame in the Virtual Channel, or returns null if there is no frame available at the moment.
    
    Returns:
  - getFirstFrameTimestamp
```
long getFirstFrameTimestamp()
```
    Returns the timestamp of the first frame ready to be dispatched or TimeEncoding.INVALID_INSTANT if there is no frame.
    The timestamp is used by the MasterChannelFrameMultiplexer to select the Virtual Channel from which the next frame is sent in case of FIFO priority scheme.
    
    Returns:
  - getParameters
```
VcUplinkManagedParameters getParameters()
```
    return the virtual channel parameters
    
    Returns:
  - setDataAvailableSemaphore
```
void setDataAvailableSemaphore(Semaphore dataAvailableSemaphore)
```
    The semaphore will be used by the virtual channel to signal to MasterChannelFrameMultiplexer that data is available to be uplinked
    
    Parameters:
    
    dataAvailableSemaphore -
