copied!<p>While the example you provide is technically a factory method, it isn't very useful. Design patterns are only beneficial insofar as they can simplify development of the target application/feature. </p> <p>Generally, the benefit of a factory method implementation comes from:</p> <ol> <li>Standardizing the creation logic for objects</li> <li>Providing a semantically meaningful interface for object construction</li> </ol> <p>It's unclear how an instance method that takes no parameters would possibly add benefit over a default constructor.</p> <p>Take a look at the <a href="http://en.wikipedia.org/wiki/Factory_method_pattern#C.23" rel="nofollow">C# example from the Wikipedia Factory Method article</a>. (copied + pasted below)</p> <pre><code>public class Complex { public double real; public double imaginary; public static Complex FromCartesianFactory(double real, double imaginary) { return new Complex(real, imaginary); } public static Complex FromPolarFactory(double modulus, double angle) { return new Complex(modulus * Math.Cos(angle), modulus * Math.Sin(angle)); } private Complex(double real, double imaginary) { this.real = real; this.imaginary = imaginary; } } Complex product = Complex.FromPolarFactory(1, Math.PI); </code></pre> <p>It is useful, because it specifies two factory methods, each with clearly defined parameters and a clearly defined interpretation of how those parameters would be used to construct a valid instance of a well-defined object. In addition, the constructor is <code>private</code> and the factory method is <code>static</code>, which ensures that the only means of constructing an instance of that object is to use the factory method. While it doesn't apply to this example particularly (because all possible <code>double</code> parameter values are valid), it would make sense to put validation logic in the factory method or constructor as well. </p> <p>In general, <strong>the purpose of a factory method is to reduce code complexity by encapsulating object construction</strong> and it is unclear how the example you provided would accomplish that objective.</p>
