Examples of erjang.EInputStream

erjang.EInputStream
Provides a stream for decoding Erlang terms from external format.
Note that this class is not synchronized, if you need synchronization you must provide it yourself.

    byte[] data = new byte[stated_length-4];
    in.readFully(data);


    this.in = new EInputStream(data);
