<title>Jinterface 1.2</title>
<section>
<title>Improvements and New features</title>
<list type="bulleted">
<item>
<p>A new class, AbstractConnection, has been added to deal
with most of the aspects of the Erlang communication
protocol, and which can be subclassed in order to provide
different levels of support to the application as necessary.
OtpConnection is now a subclass to AbstractConnection.</p>
</item>
<item>
<p>OtpCookedConnection is a new subclass to
AbstractConnection, which together with OtpNode provides an
intuitive mailbox-based communication mechanism. By using
this interface, applications are no longer required to
manage connections explicitly, since the OtpNode now opens
and manages connections to remote nodes as needed. Outgoing
messages are sent through mailboxes and automatically
dispatched through the correct connections to
the destination node, while incoming messages are queued in
the destination mailbox. This allows parts of an
application to communicate with several peers
simultaneously without the need to sort and dispatch
incoming messages. Additionally, mailboxes can be linked
with Erlang processes or with each other, in much the same
manner that Erlang processes can be linked together.</p>

<section>
<title>Changes and additions</title>
<list type="bulleted">
<item>
<p>The node class hierarchy has changed. The top class
is now AbstractNode, and direct subclasses are OtpPeer and
OtpLocalNode, of which the latter is extended by OtpNode and
OtpSelf. This does not change the functionality of any of
the existing classes or methods that take node arguments,
however it was necessary in order to group OtpNode and
OtpSelf and to provide some common methods for them.</p>
</item>
<item>
<p>OtpServer is now deprecated. Its functionality has
been added to OtpSelf.</p>
</item>
<item>
<p>An open OtpConnection no longer requires service on
a regular basis in order to keep the remote Erlang node from
disconnecting. OtpConnection now extends java.lang.Thread so
it can keep the connection open and respond to ticks when
needed, without intervention from the application. Incoming
messages are automatically received and queued for
subsequent retrieval through one of the receive methods.</p>
</item>
<item>
<p>Tracing of inter-node communication can now be set
on a per-connection basis. The system property
OtpConnection. Trace is still used as before, but now sets
only the initial trace level for new connections. Once a
connection has been created, its current trace level can be
set or retrieved through new methods setTraceLevel and
getTraceLevel.</p>
</item>
<item>
<p>Constructors for OtpErlangAtom and OtpErlangTuple
previously declared that OtpErlangDataException would be
thrown for certain types of input. These constructors now
throw java.lang.IllegalArgumentException instead, which is
a runtime exception and is therefore not declared
explicitly, nor is it necessary for the caller to
explicitly catch it. The rules for creating atoms and
tuples have not changed however.</p>
</item>
<item>
<p>Some of the constructors for OtpErlangPid, OtpErlangPort
and OtpErlangRef are now deprecated. The various
OtpNode classes provide factory methods instead.</p>
</item>
<item>
<p>OtpErlangObject and all subclasses representing
Erlang data types now implement java.io.Serializable and
java.lang.Cloneable.</p>
</item>

<p>A user's guide is now available.</p>

<title>Fixed Bugs and Malfunctions</title>

<item>
<p>A bug in the MD5 handshaking code, that could cause the
connection to fail when the Java node was run in a 7-bit
character encoding environment, has now been fixed.</p>
<p>Own Id: OTP-3512</p>
</item>
<item>
<p>A bug in OtpErlangList, which caused message corruption
when empty list where encoded, is fixed.</p>
