Method Detail
-
useSkyPos
protected abstract Outcome useSkyPos(double raDeg, double decDeg, long lrow)
Does the work of consuming the sky position corresponding to an activated row.- Parameters:
raDeg
- right ascension in degreesdecDeg
- declination in degreeslrow
- row index- Returns:
- outcome, may have null message if nothing interesting to say
-
invokeOnEdt
public boolean invokeOnEdt()
Description copied from interface:Activator
Indicates how this activator'sactivateRow
method should be executed. If true, it is intended to be invoked synchronously on the Event Dispatch Thread. If false, it is intended to be invoked asynchronously on some less time-critical thread. False should be returned if this activator may be time-consuming.- Specified by:
invokeOnEdt
in interfaceActivator
- Returns:
- true if it is a good idea to invoke this activator on the EDT
-
activateRow
public Outcome activateRow(long lrow, ActivationMeta meta)
Description copied from interface:Activator
Invokes some kind of action on the table row indicated by a given index.Note that the row index supplied is that from the TopcatModel's DataModel, not the Apparent Table, so that remapping the row index according to any current row sorting has already been applied. Possibly that's not the way it should have been done, and it may be desirable to change that in future, but at time of writing that's the way it is.
- Specified by:
activateRow
in interfaceActivator
- Parameters:
lrow
- row indexmeta
- additional activation metadata if available; may be null if no special information is available- Returns:
- outcome
