		<h2 id="SimulatingOperationsWithCustomJavaCode">Simulating Operations With Custom Java Code</h2>
		<p>To simulate a model with operations it is possible to use custom Java code that mocks the desired behavior or even to simulate against an existing java backend. 
			<br/>For that to work, it is required to provide one or more custom java classes having a method with a matching signature. 
		</p>
		<p>

		</p>
		<p>To simulate the statechart above, a new Java Class must be created matching the method signature defined in the statechart. This class must be placed onto the classpath of the
			<br/>statecharts project. 
		</p>
		<pre class="prettyprint"><code>package example;
public class Calculator {
   public int add(int param1, int param2) {
      return param1 + param2;
   }
}
</code></pre>
		<p>This custom class can be passed to the run configuration as 
			<strong>Operation Class</strong>, shown in the figure below. It is possible to pass multiple java classes seperated by a comma.
			<br/>If the simulation is executed, the variable result gets the value 2.

		<h2 id="GeneratingCode">Generating Code</h2>
		<p>For configuring the code generation process, YAKINDU Statechart Tools uses a textual generator model called 
			<strong>SGen</strong>. It can be created either by using the provided wizard 
			<strong>Yakindu Statechart Generator Model</strong> or by creating a new text file with the file extension &#8218;.sgen&#8217;.
			<br/>To create a generator model with the wizard,
		</p>
		<ol>
			<li>Click 
				<strong>File</strong> &gt; 
				<strong>New</strong> &gt; 
				<strong>Other...</strong> &gt; 
				<strong>Yakindu Statechart Generator Model</strong>
			</li>
			<li>Type a name and click 
				<strong>Next</strong>
			</li>
			<li>Choose the desired generator, i.e. 
				<strong>YAKINDU Java Code Generator</strong>
			</li>
			<li>Check the model(s) to generate code from and click 
				<strong>Finish</strong>
			</li>
		</ol>
		<p>
			<img border="0" src="images/genmodelwizardchooselanguage.jpg"/>
		</p>
		<p>The result is an .sgen file of the following format: </p>
		<pre class="prettyprint"><code>GeneratorModel for [GeneratorId] {
	statechart [StatechartReference] {
		feature [Feature] {
			[ParameterName] = [ParameterValue]
		}
	}
}
 
</code></pre>
		<p>The [GeneratorId] is the unique id of the Generator. Currently, the following Generators are supported out of the box:</p>
		<ol>
			<li>yakindu::java &#8211; Generator ID for the Java Code Generator </li>
			<li>yakindu::c &#8211; Generator ID for the C Code Generator</li>
			<li>yakindu::xpand &#8211; Generator ID for custom Xpand based Code Generators</li>
			<li>yakindu::generic &#8211; Generator ID for custom Java based Code Generators  </li>
		</ol>
		<p>One GeneratorModel can contain several [StatechartReference]s. These are cross references to statechart models for which the code should be generated. For each reference, the generator process can be configured with [Feature]s. Each Feature consists of several parameters. These parameters can be configured with [ParameterName] = [ParameterValue].</p>
		<p>The Generator Model is executed by a builder. Thus, the artifacts are generated automatically if 
			<strong>Project</strong> &gt; 
			<strong>Build Automatically</strong> is checked. If you want to execute your Generator Model by hand, select 
			<strong>Generate Statechart Artifacts</strong> from the 
			<strong>Package Explorer&#8217;s</strong> context menu.
