A constraint describes additional information about a data entity.

It's possible to add constraints to a ConstrainedProperty instance through regular setters, but chainable setters are also available to make it possible to easily define a series of constraints, for example:

ConstrainedBean constrained = new ConstrainedBean()
 .unique("firstName", "lastName")
 .defaultOrder("city")
 .defaultOrder("lastName")
 .defaultOrder("firstName");

A constrained bean is typically added to a Constrained bean in its constructor.

The property name refers to the actual name of the bean property. However, this sometimes doesn't correspond to its conceptual usage.

All the fields in a form can be generated at once by using the generateForm methods, or individual fields can be generated through the generateField method.

Besides implementing all the required interfaces for you, it also sets up the underlying data structures in a lazy fashion.

So, consider a class Foo and another class FooMetaData.

The generation of the navigation depends on a collection of block and value IDs that should be defined in a template.

Validation is bound to subjects that have distinct names.
