Class BlockDataInputStream

java.lang.Object
  java.io.InputStream
      java.io.FilterInputStream
          org.j3d.io.BlockDataInputStream

All Implemented Interfaces:

java.io.Closeable, java.io.DataInput

public class BlockDataInputStream
extends java.io.FilterInputStream
implements java.io.DataInput

A data input stream which allows reading of arrays of primative 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.
