Package com.vaadin.data.util

Provides implementations of Property, Item and Container interfaces, and utilities for the data layer.

Various Property, Item and Container implementations are provided in this package. Each implementation can have its own sets of constraints on the data it encapsulates and on how the implementation can be used. See the class javadocs for more information.

Interface Summary

Interface	Description
AbstractBeanContainer.BeanIdResolver<IDTYPE,BEANTYPE>	Resolver that maps beans to their (item) identifiers, removing the need to explicitly specify item identifiers when there is no need to customize this.
ItemSorter	An item comparator which is compatible with the Container.Sortable interface.
VaadinPropertyDescriptor<BT>	Property descriptor that can create a property instance for a bean.

AbstractContainer.BaseItemSetChangeEvent	An event object specifying the container whose Item set has changed.
AbstractContainer.BasePropertySetChangeEvent	An event object specifying the container whose Property set has changed.
AbstractInMemoryContainer<ITEMIDTYPE,PROPERTYIDCLASS,ITEMCLASS extends Item>	Abstract Container class that handles common functionality for in-memory containers.
AbstractInMemoryContainer.BaseItemAddEvent	An Event object specifying information about the added items.
AbstractInMemoryContainer.BaseItemRemoveEvent	An Event object specifying information about the removed items.
AbstractProperty<T>	Abstract base class for Property implementations.
AbstractProperty.ReadOnlyStatusChangeEvent	An Event object specifying the Property whose read-only status has been changed.
BeanContainer<IDTYPE,BEANTYPE>	An in-memory container for JavaBeans.
BeanItem<BT>	A wrapper class for adding the Item interface to any Java Bean.
BeanItemContainer<BEANTYPE>	An in-memory container for JavaBeans.
BeanUtil	Utility class for Java Beans information access.
ContainerHierarchicalWrapper	A wrapper class for adding external hierarchy to containers not implementing the Container.Hierarchical interface.
ContainerOrderedWrapper	A wrapper class for adding external ordering to containers not implementing the Container.Ordered interface.
DefaultItemSorter	Provides a default implementation of an ItemSorter.
DefaultItemSorter.DefaultPropertyValueComparator	Provides a default comparator used for comparing Property values.
FilesystemContainer	A hierarchical container wrapper for a filesystem.
GeneratedPropertyContainer	Container wrapper that adds support for generated properties.
GeneratedPropertyContainer.GeneratedProperty<T>	Property implementation for generated properties
HierarchicalContainer	A specialized Container whose contents can be accessed like it was a tree-like structure.
HierarchicalContainerOrderedWrapper	A wrapper class for adding external ordering to containers not implementing the Container.Ordered interface while retaining Container.Hierarchical features.
IndexedContainer	An implementation of the Container.Indexed interface with all important features.
IndexedContainer.ItemSetChangeEvent	An event object specifying the list whose Item set has changed.
LegacyPropertyHelper	Deprecated. This is only used internally for backwards compatibility
ListSet<E>	ListSet is an internal Vaadin class which implements a combination of a List and a Set.
MethodProperty<T>	Proxy class for creating Properties from pairs of getter and setter methods of a Bean property.
MethodPropertyDescriptor<BT>	Property descriptor that is able to create simple MethodProperty instances for a bean, using given accessors.
NestedMethodProperty<T>	Nested accessor based property for a bean.
NestedPropertyDescriptor<BT>	Property descriptor that is able to create nested property instances for a bean.
ObjectProperty<T>	A simple data object containing one typed value.
PropertyFormatter<T>	Deprecated. As of 7.0, replaced by Converter
PropertysetItem	Class for handling a set of identified Properties.
PropertyValueGenerator<T>	PropertyValueGenerator for GeneratedPropertyContainer.
TextFileProperty	Property implementation for wrapping a text file.
TransactionalPropertyWrapper<T>	Wrapper class that helps implement two-phase commit for a non-transactional property.
