Class ByteArrayInputStream

java.lang.Object
  RandomAccessInputStream
      com.smaxe.io.ByteArrayInputStream

All Implemented Interfaces:

java.io.DataInput

public final class ByteArrayInputStream
extends RandomAccessInputStream
implements java.io.DataInput

ByteArrayInputStream - InputStream implementation based on byte array.

Note: The implementation is:
- not thread-safe.
- 1.1 compatible
DataInput implementation is AMF0(3) compatible (rather than DataInputStream).
