Constructor Detail

OfflineEventLogging

public OfflineEventLogging(ClickControl clickControl,
                           PamDataBlock pamDataBlock)

Method Detail

setTableData

public void setTableData(PamDataUnit pamDataUnit)

Description copied from class: SQLLogging

Callback function when new data are created that allows the user to set the data for each column. Columns that have data which can be filled automatically (counters, primary keys and columns cross referenced to data in other tables) are filled automatically in fillTableData()

Specified by:

setTableData in class SQLLogging

createDataUnit

protected boolean createDataUnit(long timeMilliseconds,
                                 int databaseIndex)

Description copied from class: SQLLogging

Turn the data, which have been transferred back into the PamTableItems back into a useable data unit and put it into the datablock.

Overrides:

createDataUnit in class SQLLogging

Returns:

true if a data unit was sucessfully created

getViewerLoadClause

public java.lang.String getViewerLoadClause(PamViewParameters pvp)

Overrides:

getViewerLoadClause in class SQLLogging

saveOfflineData

public boolean saveOfflineData(DBControlUnit dbControlUnit,
                               java.sql.Connection connection)

Description copied from class: SQLLogging

Save offline data in viewer mode.

This is a pretty basic function which assumes pretty much a 1:1 correspondence between data loaded into the viewer and data to be saved.

Three types of saving to do

1. Pre existing 1:1 correspondence between data in memory and database
2. Viewer will have added or removed data (e.g. map comments may easily have added data)
3. Weird stuff like in the click detector where the database is only holding information about a subset of clicks held in the binary data files

Should be able to deal with first tow here, but functions must override for 3.

Overrides:

saveOfflineData in class SQLLogging

Returns:

deleteEventClicks

private void deleteEventClicks(java.sql.Connection connection,
                               int[] deleteIndexes)
