+Most of the default methods we find in @IModel@ are meant to leverage Lambda expressions to transform model object. The following is a short reference for such methods:
+
+* *filter(predicateFilter)*: Returns a @IModel@ checking whether the predicate holds for the contained object, if it is not null. If the predicate doesn't evaluate to true, the contained object will be null. Example:
+ {divcontainer:li-nested-content}
+ {code:java}
+ //the filtered model will have a null model object if person's name
+ //is not "Jane"
+ IModel<Person> janeModel = Model.of(person)
+ .filter((p) -> p.getName().equals("Jane"));
+ {code}
+ {divcontainer}
+* *map(mapperFunction)*: Returns a @IModel@ applying the given mapper to the contained object, if it is not null. Example:
+ {divcontainer:li-nested-content}
+ {code:java}
+ //the new model will contain the person's first name
+ IModel<String> personNameModel = Model.of(person).map(Person::getName);
+ {code}
+ {divcontainer}
