the class BeanModel method get.

/**
 * Uses Beans introspection to locate a property or method with name
 * matching the key name. If a method or property is found, it's wrapped
 * into {@link freemarker.template.TemplateMethodModelEx} (for a method or
 * indexed property), or evaluated on-the-fly and the return value wrapped
 * into appropriate model (for a non-indexed property) Models for various
 * properties and methods are cached on a per-class basis, so the costly
 * introspection is performed only once per property or method of a class.
 * (Side-note: this also implies that any class whose method has been called
 * will be strongly referred to by the framework and will not become
 * unloadable until this class has been unloaded first. Normally this is not
 * an issue, but can be in a rare scenario where you create many classes on-
 * the-fly. Also, as the cache grows with new classes and methods introduced
 * to the framework, it may appear as if it were leaking memory. The
 * framework does, however detect class reloads (if you happen to be in an
 * environment that does this kind of things--servlet containers do it when
 * they reload a web application) and flushes the cache. If no method or
 * property matching the key is found, the framework will try to invoke
 * methods with signature
 * <tt>non-void-return-type get(java.lang.String)</tt>,
 * then <tt>non-void-return-type get(java.lang.Object)</tt>, or
 * alternatively (if the wrapped object is a resource bundle)
 * <tt>Object getObject(java.lang.String)</tt>.
 * @throws TemplateModelException if there was no property nor method nor
 * a generic <tt>get</tt> method to invoke.
