Class	Description
DataProvider	Provides an interface to be implemented by a Data Adapter in order to attach a Data Provider to Lightstreamer Kernel.
DataProviderException	Thrown by the init method in DataProvider if there is some problem that prevents the correct behavior of the Data Adapter.
DiffAlgorithm	Enumerative class that lists the available "diff" algorithms that can be specified in ItemEventListener.declareFieldDiffOrder(java.lang.String, java.util.Map<java.lang.String, com.lightstreamer.interfaces.data.DiffAlgorithm[]>) and ItemEventListener.smartDeclareFieldDiffOrder(java.lang.Object, java.util.Map<java.lang.String, com.lightstreamer.interfaces.data.DiffAlgorithm[]>).
FailureException	Thrown by the subscribe and unsubscribe methods in DataProvider if the method execution has caused a severe problem that can compromise future operation of the Data Adapter.
IndexedItemEvent	Provides to the Data Adapter an alternative interface for creating ItemEvents in order to send updates to Lightstreamer Kernel.
ItemEvent	Provides to the Data Adapter a base interface for creating ItemEvents in order to send updates to Lightstreamer Kernel.
ItemEventListener	Used by Lightstreamer Kernel to receive the ItemEvents and other kinds of events related with the Item subscription lifecycle.
OldItemEvent	Provides to the Data Adapter a special interface for creating ItemEvents in order to send updates to Lightstreamer Kernel.
SmartDataProvider	Provides an extended interface to be implemented by a Data Adapter in order to attach a Data Provider to Lightstreamer Kernel.
SubscriptionException	Thrown by the subscribe and unsubscribe methods in DataProvider if the request cannot be satisfied.
