Interface Summary

AggregationFunctionFactory	Interface to implement for factories of aggregation functions.
BaseCondition	Marker interface for conditions reported.
ConditionHandler	Interface for a handler registered with an engine instance to receive reported engine conditions.
ConditionHandlerFactory	Factory for engine condition handler instance(s).
EPLScriptContext	Available when using JSR-223 scripts or MVEL, for access of script attributes.
ExceptionHandler	Interface for an exception handler.
ExceptionHandlerFactory	Factory for exception handler instance(s).
SQLColumnTypeConversion	Implement this interface when providing a callback for SQL input parameter and column result processing for a statement, converting an input parameter or converting an output column value into any other value.
SQLOutputRowConversion	Implement this interface when providing a callback for SQL row result processing for a statement, converting each row's values into a POJO.
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 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

ConditionHandlerContext	Context provided to ConditionHandler implementations providing engine-condition-contextual information.
ConditionHandlerFactoryContext	Context provided to ConditionHandlerFactory implementations providing engine contextual information.
ConditionPatternEngineSubexpressionMax	Indicates that on the engine level the followed-by pattern operator, regardless whether parameterized with a max number of sub-expressions or not, has reached the configured engine-wide limit at runtime.
ConditionPatternSubexpressionMax	Indicates that the followed-by pattern operator, when parameterized with a max number of sub-expressions, has reached that limit at runtime.
EPLExpressionEvaluationContext	Provides expression evaluation context information in an expression.
EPLMethodInvocationContext	Invocation context for method invocations that invoke static methods or plug-in single-row functions.
ExceptionHandlerContext	Context provided to ExceptionHandler implementations providing exception-contextual information as well as the exception itself.
ExceptionHandlerFactoryContext	Context provided to ExceptionHandlerFactory implementations providing engine contextual information.
SQLColumnTypeContext	For use with SQLColumnTypeConversion, context of column conversion.
SQLColumnValueContext	For use with SQLColumnTypeConversion, context of column conversion.
SQLInputParameterContext	For use with SQLColumnTypeConversion, context of parameter conversion.
SQLOutputRowTypeContext	For use with SQLOutputRowConversion, context of row conversion.
SQLOutputRowValueContext	For use with SQLOutputRowConversion, context of row conversion.
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 informaion.
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 about the named window and the type of events held, handle for posting insert and remove streams and factory for event bean instances.
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.
