Dispose

Apply f to the resource and return it after closing the resource If you don't wish to close the resource (e.g. if you are creating an iterator on file contents), use flatMap instead

This keeps the resource open during the context of this flatMap and closes when done

This will immediately apply f on the resource and close the resource

Dispose this resource and return it Note: If you are using map followed by get, consider using apply instead

Generate a self closing iterator from this disposable resource

This will apply f on the resource while it is open
