/**
* Returns a fragment of Java code that can be used to set a property to match the editors current
* state. This method is intended for use when generating Java code to reflect changes made
* through the property editor.
*
* <p>The code fragment should be context free and must be a legal Java expression as specified by
* the JLS.
*
* <p>Specifically, if the expression represents a computation then all classes and static members
* should be fully qualified. This rule applies to constructors, static methods and non primitive
* arguments.
*
* <p>Caution should be used when evaluating the expression as it may throw exceptions. In
* particular, code generators must ensure that generated code will compile in the presence of an
* expression that can throw checked exceptions.
*
* <p>Example results are:
*
* <ul>
* <li>Primitive expresssion: <code>2</code>
* <li>Class constructor: <code>new
* java.awt.Color(127,127,34)</code>
* <li>Static field: <code>java.awt.Color.orange</code>
* <li>Static method: <code>javax.swing.Box.createRigidArea(new java.awt.Dimension(0, 5))</code>
* </ul>
*
* @return a fragment of Java code representing an initializer for the current value. It should
* not contain a semi-colon ('<code>;</code>') to end the expression.
