Method Details

createOfflineDataMap

void createOfflineDataMap(Window parentFrame)

Create a basic map of the data including first and last times and some kind of data/unit time count plus ideally some kind of start and stop time list of where there are gaps in the data.

data source name

getDataLocation

String getDataLocation()

Get the data location. This may be a specific file, or might be a folder if data are in many files, a URI, etc.

Returns:

store locations

loadData

boolean loadData(PamDataBlock dataBlock,
 OfflineDataLoadInfo offlineDataLoadInfo,
 ViewLoadObserver loadObserver)

Load data for a given datablock between two time limits.

Parameters:

dataBlock - datablock owner of the data

loadObserver -

dataStart - start time in milliseconds

dataEnd - end time in milliseconds

Returns:

true if load successful.

saveData

boolean saveData(PamDataBlock dataBlock)

Save data previously loaded from the store during offline viewing.

Parameters:

dataBlock - datablock owner of the data

Returns:

true if saved or save not needed. False if an error prevents saving.

rewriteIndexFile

boolean rewriteIndexFile(PamDataBlock dataBlock,
 OfflineDataMapPoint dmp)

Moved this function over from binary data store. Many storage systems may not be able to do this, but some might !

Parameters:

dataBlock -

dmp -

Returns:

getDatagramManager

DatagramManager getDatagramManager()
