public class BlockDataInputStream
extends FilterInputStream
implements DataInput

A data input stream which allows reading of arrays of primitive types as well as the standard types a DataInputStream allows. This class is considerably faster then the standard DataInputStream provided by the standard JDK. This class is not thread safe. Do not call two methods at the same time.
