Interface Summary

EPServiceProviderSPI	A service provider interface that makes available internal engine services.
EPServicesContextFactory	Interface for a factory class to provide services in a services context for an engine instance.
EPStatementDispatch	Interface for statement-level dispatch.
EPStatementSPI	Statement SPI for statements operations for state transitions and internal management.
EPStatementStopMethod	Method to call to stop an EPStatement.
ExtensionServicesContext	Marker interface for extension services that provide additional engine or statement-level extensions, such as views backed by a write-behind store.
InternalEventRouter	Interface for a service that routes events within the engine for further processing.
StatementContextFactory	Interface for a factory class that makes statement context specific to a statement.
StatementExtensionSvcContext	Statement-level extension services.
StatementLifecycleSvc	Handles statement management.
StatementLockFactory	Factory for the managed lock that provides statement resource protection.

Class Summary

EPStatementObjectModelHelper	Helper methods for use by the statement object model.
EPStatementStartMethod	Starts and provides the stop method for EQL statements.
InsertIntoLatchFactory	Class to hold a current latch per statement that uses an insert-into stream (per statement and insert-into stream relationship).
InsertIntoLatchSpin	A spin-locking implementation of a latch for use in guaranteeing delivery between a single event produced by a single statement and consumable by another statement.
InsertIntoLatchWait	A suspend-and-notify implementation of a latch for use in guaranteeing delivery between a single event produced by a single statement and consumable by another statement.
PatternListenerDispatch	Dispatchable for dispatching events to update listeners.
StatementContext	Contains handles to the implementation of the the scheduling service for use in view evaluation.
StatementContextFactoryDefault	Default implementation for making a statement-specific context class.
StatementLifecycleSvcImpl	Provides statement lifecycle services.
StatementLockFactoryImpl	Provides statement-level locks.
SubSelectHolder	Entry holding lookup resource references for use by SubSelectStreamCollection.
SubSelectStreamCollection	Holds stream information for subqueries.
UpdateDispatchFutureSpin	UpdateDispatchFutureSpin can be added to a dispatch queue that is thread-local.
UpdateDispatchFutureWait	UpdateDispatchFutureWait can be added to a dispatch queue that is thread-local.
UpdateDispatchViewBase	Convenience view for dispatching view updates received from a parent view to update listeners via the dispatch service.
UpdateDispatchViewBlockingSpin	Convenience view for dispatching view updates received from a parent view to update listeners via the dispatch service.
UpdateDispatchViewBlockingWait	Convenience view for dispatching view updates received from a parent view to update listeners via the dispatch service.
UpdateDispatchViewNonBlocking	Convenience view for dispatching view updates received from a parent view to update listeners via the dispatch service.
