Exception Summary

Package com.itmill.toolkit.data.util Description

Provides various utility classes that implement the data layer functionality.

The first Property class, ObjectProperty, provides a simple class containing a typed data value. The second, MethodProperty, provides a way to bind a field of an object to the Property interface using the accessor methods for the field.

The next level of the data layer, the Item, is implemented by BeanItem, though it is only a simple wrapper to the former to provide the Item interface for any regular Java Bean.

The third level, the Container, has several implementations in the com.itmill.toolkit.data.util package.
