Examples of freemarker.ext.beans.BeansWrapper.unwrap()

freemarker.ext.beans.BeansWrapper.unwrap()
Attempts to unwrap a model into underlying object. Generally, this method is the inverse of the {@link #wrap(Object)} method. In additionit will unwrap arbitrary {@link TemplateNumberModel} instances intoa number, arbitrary {@link TemplateDateModel} instances into a date,{@link TemplateScalarModel} instances into a String, arbitrary {@link TemplateBooleanModel} instances into a Boolean, arbitrary {@link TemplateHashModel} instances into a Map, arbitrary {@link TemplateSequenceModel} into a List, and arbitrary {@link TemplateCollectionModel} into a Set. All other objects are returned unchanged. @throws TemplateModelException if an attempted unwrapping fails.
