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.
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.

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.
