-<p>OpenWire is an extensible in that it supports adding new encoding options
while still being backward compatible with previous versions of the protocol.
Every OpenWire protocol session initially starts with all encoding options
turned off and at version 1 of command marshalers. An initial WIREFORMAT_INFO
command is exchanged between the two nodes so that additional encoding features
can be enabled. If both sides request an encoding feature to be enabled then
it will be enabled. The command marshalers used will be the highest version
that they both support.</p>

-
-<p>Prefixing the size on every command is done to aid in non-blocking IO
processing so that receiver can easily determine when a whole command has been
received and can be processed. But finding out the size of command takes
additional buffering on the sender size and is not needed if the receiver is
doing blocking IO. If the SizePrefixDisabled option is enabled after the
exchange of WIREFORMAT_INFO packets, then every subsequent command will not
have the size prefixed.</p>

-<h3 id="OpenWireVersion2Specification-CommandFieldEncoding">Command Field
Encoding</h3>
-
-<p>All OpenWire commands use the same algorithm when encoding their fields.
The algorithm restricts commands to use fields that are of the following
type:</p>
-
-<ul><li>Java primitive types</li><li>String</li><li>Byte Arrays</li><li>N
Sized Byte Arrays</li><li>Throwable</li><li>Nested OpenWire
commands</li><li>Nested OpenWire command arrays</li><li>Cached Nested OpenWire
commands</li></ul>
-
-
-<p>Notice that OpenWire commands can nest other OpenWire commands in it's
fields. Care must be taken that only acyclic graphs of commands are
marshaled.</p>

-<p>The default encoding explained so far is called "loose encoding" and is the
default encoding used when OpenWire if first initialized. Loose encoding is
simple to implement does not add much CPU overhead to the
marshaling/unmarshaling process. It is able to marshal an object graph in
single pass of the object tree.</p>

-<p>Another encoding option is supported by OpenWire which is called
TightEncoding. When tight encoding is used, it uses bit streams to marshal all
the boolean values that would have taken up a byte in loose encoding to a bit
in the bit stream. To build the bit stream 2 passes through the object graph
are taken so this is more CPU intensive marshaling process but it produces a
smaller on the wire size.</p></div>
