Method Detail

create

public static TempFileProvider create(String providerType,
                                      ScheduledExecutorService executor)
                               throws IOException

Create a temporary file provider for a given type.

This is the same as calling create(final String providerType, final ScheduledExecutorService executor, false)

Parameters:

providerType - the provider type string (used as a prefix in the temp file dir name)

executor - the executor

Returns:

the new provider

Throws:

IOException - if an I/O error occurs

create

public static TempFileProvider create(String providerType,
                                      ScheduledExecutorService executor,
                                      boolean cleanExisting)
                               throws IOException

Create a temporary file provider for a given type.

Parameters:

providerType - The provider type string (used as a prefix in the temp file dir name)

executor - Executor which will be used to manage temp file provider tasks (like cleaning up/deleting the temp files when needed)

cleanExisting - If this is true, then this method will *try* to delete the existing temp content (if any) for the providerType. The attempt to delete the existing content (if any) will be done in the background and this method will not wait for the deletion to complete. The method will immediately return back with a usable TempFileProvider. Note that the cleanExisting will just act as a hint for this method to trigger the deletion of existing content. The method may not always be able to delete the existing contents.

Returns:

The new provider

Throws:

IOException - if an I/O error occurs

createTempDir

public TempDir createTempDir(String originalName)
                      throws IOException

Create a temp directory, into which temporary files may be placed.

Parameters:

originalName - the original file name

Returns:

the temp directory

Throws:

IOException - for any error

           throws IOException
