On no frame available, null is returned.

Returns:

the CEMILData frame, or null

setFrame

public void setFrame(CEMILData frame)

Sets a new CEMILData frame for this cache object.

The key generated out of frame (i.e. out of the KNX address of frame) has to be equal to the key of this LDataObject, as returned from CacheObject.getKey(). Otherwise a KNXIllegalArgumentException will be thrown.
Note that on successful set the timestamp is renewed.
