Method Detail

startProcessImpl

protected void startProcessImpl()

Description copied from class: CustomLineProvider

Implement this method to receive notification that the saving of CSV data is about to start.

You can implement this method when you extend CustomLineProvider, but it is not required.

You can use this method to initialise any resource you need to process the CSV data. For example you can open a database connection to retrieve the data as it is saved.

This method is called after setCsvSpecImpl and setLineSpecImpl.

Overrides:

startProcessImpl in class CustomLineProvider

See Also:

endProcessImpl

endProcessImpl

protected void endProcessImpl()

Description copied from class: CustomLineProvider

Implement this method to receive notification that the saving of CSV data has ended.

You can implement this method when you extend CustomLineProvider, but it is not required.

You can use this method to close any open resources that were used to handle the CSV data. For example you can close any open database connections.

This method is called last, after all hasNextLineImpl and nextLineImpl calls have been made.

Overrides:

endProcessImpl in class CustomLineProvider

See Also:

startProcessImpl

hasNextLineImpl

protected boolean hasNextLineImpl()

Description copied from class: CustomLineProvider

Implement this method to let CSV Manager know that there is another line of data to save.

This method must be implemented when you extend CustomLineProvider.

Return true from this method so long as you have more data lines to save.

Specified by:

hasNextLineImpl in class CustomLineProvider

See Also:

LineProvider.hasNextLine, nextLineImpl

nextLineImpl

protected String[] nextLineImpl()

Description copied from class: CustomLineProvider

Implement this method to supply each data line as it is saved.

This method must be implemented when you extend CustomLineProvider.

This method is where you will do the main work of providing the CSV data. Each time this method is called you will need to provide a new line of CSV data as a String[] array.

Error Handling: What happens when you cannot provide the line data for some reason? For example your database connection may fail. In this case, all you have to do is throw an Exception to let CSV Manager know about the problem. But note that if the CsvSpec.setIgnoreBadLines setting is true, then CSV Manager will not stop asking you for more data lines until you also return false from CustomLineProvider.hasNextLineImpl().
