Modifier and Type	Method and Description
protected CSVReader	createReader() Creates a new reader using last dump file as input.
protected CSVWriter	createWriter() Creates a new writer using a new created temp file as current dump file.
protected void	deleteCurrentDump() Deletes the file holding the current dump.
protected void	deleteLastDump() Deletes the file holding the last dump.
void	finish(boolean saveCurrentDump) Deletes last dump storage definitely and current one if given flag is set.
File	getDumpAsFile() Gets the current dump as file.
ImpExMedia	getDumpAsMedia() Gets the current dump as media object.
void	init() Initializes the handler by creating the first dump storage and providing a writer object to that storage when calling DumpHandler.getWriterOfCurrentDump().
protected void	switchCurrentToLastDump() Switches the reference of current dump file to last dump file.
void	switchDump() References the 'current' dump storage as 'last' dump storage (DumpHandler.getReaderOfLastDump() now provides a reader object to that storage) and creates a new 'current' dump storage (DumpHandler.getWriterOfCurrentDump() now provides a writer object to that storage).

References the 'current' dump storage as 'last' dump storage (DumpHandler.getReaderOfLastDump() now provides a reader object to that storage) and creates a new 'current' dump storage (DumpHandler.getWriterOfCurrentDump() now provides a writer object to that storage). If there was a storage referenced by 'last' it will be deleted.

Throws:

ImpExException - error while storage handling
