Specified by:

handleDatamixerEvent in interface DatamixerListener

Throws:

DatamixerException

actionToString

public java.lang.String actionToString(int action)

Returns the print name of action

Specified by:

actionToString in interface DatamixerListener

stringToAction

public int stringToAction(java.lang.String s)

Returns the value of the action named actionName

Specified by:

stringToAction in interface DatamixerListener

getActions

public java.util.List getActions()

Returns the list of available action names.

Specified by:

getActions in interface DatamixerListener

addDatamixerListener

public void addDatamixerListener(DatamixerListener listener,
