All Implemented Interfaces:

PanelOverlayDraw

Direct Known Subclasses:

ClickTrainDataBlock

public class ClickGroupDataBlock<t extends GroupDetection>
extends AcousticDataBlock<t>

Click Train data block deletes old data in a slightly different way to PamDataBlock. Where PamDataBlock starts at the beginning of the list and deletes items until one of them starts after the set time at which point it stops, ClickTrainDataBlock examins all units and deletes all of those which end before the set time. This is necessary since some click train data units last for hours, whereas others can be deleted after a couple of seconds.

                           java.lang.String dataName,

Method Detail

removeOldUnitsT

protected int removeOldUnitsT(long currentTimeMS)

Description copied from class: PamDataBlock

Removes olderPamDataUnits from memory, starting at the first unit and continuing until if finds one with data coming earlier than the given time in milliseconds.

If the data are acoustic, it tries to find the data source and looks to see how much data has been placed in the source data unit and does the calculation in samples.

Overrides:

removeOldUnitsT in class PamDataBlock<t extends GroupDetection>

Parameters:

currentTimeMS - Time in milliseconds of the first data which must be kept

Returns:

the number of units removed

canDraw

public boolean canDraw(GeneralProjector projectorInfo)

Specified by:

canDraw in interface PanelOverlayDraw

Overrides:

canDraw in class PamObservable

Returns:

Returns whether or not the object can be drawn using the given projector. The implementation of CanDraw should examine the parameter types in GeneralProjector and check that it will know how to prvide those parameters before returning true, or false otherwise.
