BEANTYPE - The type of the Beanpublic class BeanItemContainer<BEANTYPE> extends AbstractBeanContainer<BEANTYPE,BEANTYPE>
The properties of the container are determined automatically by introspecting the used JavaBean class. Only beans of the same type can be added to the container.
BeanItemContainer uses the beans themselves as identifiers. The
Object.hashCode() of a bean is used when storing and looking up beans
so it must not change during the lifetime of the bean (it should not depend
on any part of the bean that can be modified). Typically this restricts the
implementation of Object.equals(Object) as well in order for it to
fulfill the contract between equals() and hashCode().
To add items to the container, use the methods addBean(Object),
AbstractBeanContainer.addBeanAfter(Object, Object) and AbstractBeanContainer.addBeanAt(int, Object).
Also addItem(Object), addItemAfter(Object, Object) and
addItemAt(int, Object) can be used as synonyms for them.
It is not possible to add additional properties to the container.

The collection must not be empty.
BeanItemContainer(Class) can be used for
creating an initially empty BeanItemContainer.
Note that when using this constructor, the actual class of the first item
in the collection is used to determine the bean properties supported by
the container instance, and only beans of that class or its subclasses
can be added to the collection. If this is problematic or empty
collections need to be supported, use BeanItemContainer(Class)
