Class TransferUtil

java.lang.Object
  org.openrdf.sesame.sailimpl.nativerdf.datastore.TransferUtil

public class TransferUtil

extends Object

Utility class for transfering bytes to/from file channels. The utility normally will use the transferTo() and transferFrom() methods that are available in class FileChannel, but will fall back to more conventional means on platforms on which this doesn't work (JDK 1.4.x with Linux kernel 2.6.x) as a result of bug 5056395.
