Method Detail

createExportDirectory

File createExportDirectory()
                           throws IOException

Create a unique directory within which an export operation can create any necessary files and final output. The client has no control over the naming of this directory.

IOException - if there is a problem creating the output directory.

getExportFileName

String getExportFileName(String... differentiators)

a unique file name that may be created.

getExportFile

File getExportFile(String... differentiators)
                   throws IOException

This method is a convenient combination of createExportDirectory() and getExportFileName(String...).

Parameters:

Returns:

a File representing the export file to be created
