<h2>Type Safe Messages And Fields</h2>
<p>Message constructors take in all required fields and adds
the correct <b>MsgType</b> and <b>BeginString</b> for you. With
the <b>set</b> method, the compiler will not let you add a
field that is not a part of a message as defined by the
spec.</p>
<pre class='fragment'>
void sendOrderCancelRequest()
{
FIX41::OrderCancelRequest message(
FIX::OrigClOrdID("123"),
FIX::ClOrdID("321"),
FIX::Symbol("LNUX"),
FIX::Side(FIX::Side_BUY));
message.set(FIX::Text("Cancel My Order!"));
FIX::Session::sendToTarget(message, SenderCompID("TW"), TargetCompID("TARGET"));
}
</pre>
<br/><hr/>
<h2>Type Safe Field Only</h2>
<p>The <b>setField</b> method allows you to add any field to
any message.</p>See this code in <a href=
"python/sending_messages_3.html">PYTHON</a>, <a href=
"ruby/sending_messages_3.html">RUBY</a>
<pre class='fragment'>
void sendOrderCancelRequest()
{
FIX::Message message;
FIX::Header header& = message.getHeader();
header.setField(FIX::BeginString("FIX.4.2"));
header.setField(FIX::SenderCompID(TW));
header.setField(FIX::TargetCompID("TARGET"));
header.setField(FIX::MsgType(FIX::MsgType_OrderCancelRequest));
message.setField(FIX::OrigClOrdID("123"));
message.setField(FIX::ClOrdID("321"));
message.setField(FIX::Symbol("LNUX"));
message.setField(FIX::Side(FIX::Side_BUY));
message.setField(FIX::Text("Cancel My Order!"));
FIX::Session::sendToTarget(message);
}
</pre>
<br/><hr/>
<h2>No Type Safety</h2>
<p>You can also use <b>setField</b> to pass in
primitives.</p>See this code in <a href=
"python/sending_messages_2.html">PYTHON</a>, <a href=
"ruby/sending_messages_2.html">RUBY</a>
