Method Detail

handleDatamixerEvent

public void handleDatamixerEvent(DatamixerEvent e)
                          throws DatamixerException

Dispatches the event based on the event type and action. Currently event type is ignored. These actions are accepted:

• ACTION_SET_VALUE calls setValue(Value) with the value in the event.
• ACTION_WRITE calls write().
• ACTION_SET_VALUE_WRITE calls setValue(Value) with the value in the event, and then calls write().

Specified by:

handleDatamixerEvent in interface DatamixerListener

Throws:

DatamixerException
