<h1 class="topictitle1">Adding an operation</h1>
<div><p>An operation names the operation and lists the expected inputs
and outputs. The operation element may also contain a fault sub-element that
describes any error data the operation may return.</p>
<div class="section">Using these, you can declare four transmission primitives that an
endpoint can support:<ul>
<li> <strong>One-way</strong>: the endpoint receives a message.</li>
<li> <strong>Request-response</strong>: the endpoint receives a message, and sends a
correlated message.</li>
<li> <strong>Solicit-response</strong>: the endpoint sends a message, and receives a
correlated message.</li>
<li> <strong>Notification</strong>: the endpoint sends a message.</li>
</ul>
<p>You can add an operation to a port type or a port binding.</p>
<p>To
add an operation to a port type, complete the following steps:</p>
</div>
<ol>
<li class="stepexpand"><span>In the Design view, right-click your port type.</span> Click <strong>Add
Operation</strong>. To select the new operation, click the operation in the port
type object.</li>
<li class="stepexpand"><span>In the Properties view, click the <strong>General</strong> pane.</span></li>
<li class="stepexpand"><span>In the <strong>Name</strong> field, type the name of the operation.</span>
</li>
<li class="stepexpand"><span>Right click on the operation to add input, output or fault objects.</span>
Depending on an operation's inputs and outputs it can be classified
as follows:<ul>
<li><strong>One way operation</strong>: input </li>
<li><strong>Request response operation</strong>: input, output </li>
<li><strong> Solicit response operation</strong>: output, input </li>
<li><strong>Notification operation</strong>: output</li>
</ul>
</li>
<li class="stepexpand"><span>In the Properties view, type any information about the operation
you wish the user to read in the <strong>Documentation</strong> pane.</span></li>
</ol>
<div class="section"><p> <strong>Tip</strong>: You can also create a new operation for your port
type using the Outline view. Right click on a port type in the <span class="uicontrol">Port
Type</span> folder and select <span class="uicontrol">Add Operation</span>.</p>
