Interface Summary

Interface	Description
VirtualDataWindow	A virtual data window exposes externally-managed data transparently as a named window without the need to retain any data in memory.
VirtualDataWindowFactory	Factory for virtual data windows.
VirtualDataWindowFactoryFactory	A factory that the runtime invokes at deployment time to obtain the virtual data window factory.
VirtualDataWindowFactoryMode	Describes to the compiler how it should manage code for the virtual data window factory.
VirtualDataWindowForge	Factory for VirtualDataWindow.
VirtualDataWindowLookup	Represents a lookup strategy object that an EPL statement that queries a virtual data window obtains to perform read operations into the virtual data window.
VirtualDataWindowOutStream	For use with virtual data windows, handles any insert stream and remove stream events that a virtual data window may post to consuming statements.

Class Summary

Class	Description
VirtualDataWindowContext	Context for use with virtual data window factory VirtualDataWindowFactory provides contextual information about the named window and the type of events held, handle for posting insert and remove streams and factory for event bean instances.
VirtualDataWindowEvent	Base class for events related to virtual data windows.
VirtualDataWindowEventConsumerAdd	Event indicating a named-window consuming statement is being added.
VirtualDataWindowEventConsumerBase	Base class for events indicating a named-window consumer management.
VirtualDataWindowEventConsumerRemove	Event indicating a named-window consuming statement is being removed.
VirtualDataWindowEventStartIndex	Event raised when an index gets created or started via the "create index" syntax.
VirtualDataWindowEventStartIndex.VDWCreateIndexField	Captures virtual data window indexed field information.
VirtualDataWindowEventStopIndex	Event to indicate that for a virtual data window an exitsing index is being stopped or destroyed.
VirtualDataWindowEventStopWindow	This event is raised when a virtual data window is stopped.
VirtualDataWindowFactoryContext	Context for use with virtual data window factory VirtualDataWindowFactory provides contextual information as well as the handle for posting insert and remove streams and factory for event bean instances.
VirtualDataWindowFactoryFactoryContext	Context for use with a virtual data window factory factory VirtualDataWindowFactoryFactory.
VirtualDataWindowFactoryModeManaged	Use this class to provide a virtual data window factory wherein there is no need to write code that generates code.
VirtualDataWindowForgeContext	Context for use with virtual data window forge VirtualDataWindowForge provides contextual information about the named window and the type of events held.
VirtualDataWindowKeyRange	Provides a range as a start and end value, for use as a paramater to the lookup values passed to the VirtualDataWindowLookup lookup method.
VirtualDataWindowLookupContext	Context passed to VirtualDataWindow upon obtaining a lookup strategy for use by an EPL statement that queries the virtual data window.
VirtualDataWindowLookupFieldDesc	As part of a lookup context, see VirtualDataWindowLookupContext, this object encapsulates information about a single property in a correlated where-clause.

Enum Summary

Enum	Description
VirtualDataWindowLookupOp	Enumeration for indicating the type of operator for a lookup against a virtual data window, see VirtualDataWindowLookupContext.
