Class Summary

Class	Description
AbstractBackEndDataProvider<T,F>	Abstract base class for implementing back end data providers.
AbstractComponentDataGenerator<T>	Abstract class used as base for DataGenerators that need to manage the lifecycle of components, according to what items are requested or destroyed.
AbstractDataProvider<T,F>	Abstract data provider implementation which takes care of refreshing data from the underlying data provider.
AbstractDataView<T>	Abstract data view implementation which handles parts that apply for any type of data.
AbstractLazyDataView<T>	Abstract lazy data view implementation which handles the interaction with a data communicator.
AbstractListDataView<T>	Abstract list data view implementation which provides common methods for fetching, filtering and sorting in-memory data to all ListDataView subclasses.
BeanDataGenerator<T>	A DataGenerator that sends all the fields of the objects in the model to the client, using the field names as property names.
CallbackDataProvider<T,F>	Data provider that uses one callback for fetching items from a back end and another callback for counting the number of available items.
ComponentDataGenerator<T>	A DataGenerator that manages the creation and passivation of components generated by ComponentRenderers.
CompositeDataGenerator<T>	A DataGenerator that aggregates multiple DataGenerators and delegates the data generation to them.
ConfigurableFilterDataProviderWrapper<T,Q,C,F>	A configurable data provider that wraps another data provider by combining any filter from the component with the configured filter and passing that to the wrapped provider through the query.
DataChangeEvent<T>	An event fired when the data of a DataProvider changes.
DataChangeEvent.DataRefreshEvent<T>	An event fired when a single item of a DataProvider has been updated.
DataCommunicator<T>	DataProvider base class.
DataProviderWrapper<T,F,M>	Wrapper class for modifying, chaining and replacing filters and sorting in a query.
FilterUtils	Internal filter related utilities for data provider.
InMemoryDataProviderHelpers	Helper methods for implementing InMemoryDataProviders.
ItemCountChangeEvent<T extends Component>	Event describing the item count change for a component.
KeyMapper<V>	KeyMapper is the simple two-way map for generating textual keys for objects and retrieving the objects later with the key.
ListDataProvider<T>	DataProvider wrapper for Collections.
Query<T,F>	Immutable query object used to request data from a backend.
QuerySortOrder	Sorting information for Query.
QuerySortOrderBuilder	Helper classes with fluent API for constructing QuerySortOrder lists.
SortOrder<T>	Sorting information for one field.
SortOrderBuilder<T extends SortOrder<V>,V>	Base class for helper classes with fluent API for constructing sort order lists.
