Method Summary

String

getNextFilename(T owner, String suggestedFilename) Get the next file name.

Method Detail

getNextFilename

String getNextFilename(T owner,
                       String suggestedFilename)

Get the next file name. This method should never return the same file name more than one time (given a single implementor instance). The generator implementation should not concern itself with the underlying file system or if the file already exists or not (this is a task for the DataWriterFactory implementation).

Parameters:

owner - The owner of the data in the file

suggestedFilename - A default suggested file name (can be null)

Returns:

A unique file name
