 /**
- * Convenience class for reflection-based object creation.
+ * Factory implementation that use reflection to create instance of given class.
+ * <p>
+ * There are 2 modes of factory: singleton and non-sigletton.
+ * <p>
+ * Class that should be created by {@link IgniteReflectionFactory} (component class) have
to be
+ * public java POJO with public setters for field
+ * for which property injection will be used (see {@link #setProperties(Map)}).
+ * <p>
+ * <h1 class="header">Configuration</h1>
+ * <h2 class="header">Mandatory</h2>
+ * The following configuration parameters are mandatory:
+ * <ul>
+ * <li>Component class - class to be created (see {@link #setComponentClass(Class)}.
+ * It have to be public java POJO class with default constructor
+ * and public setters to be used by properties injection (see {@link #setProperties(Map)})</li>
+ * </ul>
+ * <h2 class="header">Optional</h2>
+ * The following configuration parameters are optional:
+ * <ul>
+ * </li>
+ * <li>Singleton mode (see {@link #setSingleton(boolean)})</li>
+ * <li>Properties map (see {@link #setProperties(Map)}</li>
+ * <li>With method (see {@link #setWithMethod(Object, String, Serializable)}</li>

+ * Factory<CacheStoreSessionListener> factory =
