Class OfflineDataMap<TmapPoint extends OfflineDataMapPoint>

java.lang.Object
  PamguardMVC.OfflineDataMap<TmapPoint>

public abstract class OfflineDataMap<TmapPoint extends OfflineDataMapPoint>
extends java.lang.Object

Class which get's held within a PamDataBlock which provides summary information on data within that block when operating in viewer mode.

It is possible that some datablocks may own two of these things - one for database data and one for binary stored data.

an iterator over the map contents.

getParentDataBlock

public PamDataBlock getParentDataBlock()

Returns:

the parentDataBlock

addDataPoint

public void addDataPoint(TmapPoint mapPoint)

Add a new map point into the list.

Parameters:

mapPoint - new map point to add

getNumMapPoints

public int getNumMapPoints()

Returns:

the total number of map points.

sortMapPoints

public void sortMapPoints()

Sort all map points into ascending order based on start time.

this should be called after all data have been loaded.

getFirstDataTime

public long getFirstDataTime()

Returns:

the firstDataTime

setFirstDataTime

public void setFirstDataTime(long firstDataTime)

Parameters:

firstDataTime - the firstDataTime to set

getLastDataTime

setLastDataTime

public void setLastDataTime(long lastDataTime)

Parameters:

lastDataTime - the lastDataTime to set

getHighestPoint

public double getHighestPoint(int vScaleType)

Parameters:

vScaleType -

Returns:

the highestPoint

getLowestPoint

public double getLowestPoint(int vScaleType)

Returns:
