Method Details

pamStart

public void pamStart()

Description copied from class: PamProcess

Called for each process to tell it to start (may not be necessary for processes which are listening for data anyway).

Specified by:

pamStart in class PamProcess

pamStop

public void pamStop()

Description copied from class: PamProcess

Stops the process.

Specified by:

pamStop in class PamProcess

getTrackedGroups

public TrackedGroupDataBlock getTrackedGroups()

newData

public void newData(PamObservable o,
 PamDataUnit dataUnit)

Check if a group already exists, and if so add the data to that group. Otherwise create a new group.

Overrides:

newData in class PamProcess

getDifarRangeInfo

public TrackedGroupCrossingInfo getDifarRangeInfo(TrackedGroupDataUnit trackedGroupDataUnit)

Called just before a difar unit is stored. Looks at other channels that have recently had a data unit stored and decides whether or not they are likely to be the same vocalisation. If they are, calculate a crossed bearing to them both. If > 2 channels do some kind of optimised fit.

Parameters:

trackedGroupDataUnit -

Returns:

information about the range (will already have been put into affected units)
