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.
DataCommunicator.EmptyDataProvider<T1>	In-memory data provider with no items.
DataCommunicator.Filter<F>	Wraps the component's filter object with the meta information whether this filter changing should trigger the item count change event.
DataProviderWrapper<T,F,M>	Wrapper class for modifying, chaining and replacing filters and sorting in a query.
DataViewUtils	Internal utility class used by data view implementations and components to simplify the filtering and sorting handling, but not limited to it.
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.
