Classes
Class | Description | |
---|---|---|
![]() | ExecNodeQueryStrategy |
Query strategy for building a join tuple set by using an execution node tree.
|
![]() | HistoricalDataQueryStrategy | Query strategy for use with net.esper.view.HistoricalEventViewable
to perform lookup for a given stream using the poll method on a viewable.
|
![]() | JoinExecStrategyDispatchable |
This class reacts to any new data buffered by registring with the dispatch service.
When dispatched via execute, it takes the buffered events and hands these to the join
execution strategy.
|
![]() | JoinExecutionStrategyImpl | Join execution strategy based on a 3-step GetSelectListEvents of composing a join set, filtering the join set and
indicating.
|
![]() | JoinSetComposerFactory |
Factory for building a net.esper.eql.join.JoinSetComposer from analyzing filter nodes, for
fast join tuple result set composition.
|
![]() | JoinSetComposerImpl | Implements the function to determine a join result set using tables/indexes and query strategy
instances for each stream.
|
![]() | JoinSetFilter |
Processes join tuple set by filtering out tuples.
|
Interfaces
Interface | Description | |
---|---|---|
![]() | JoinExecutionStrategy | Strategy for executing a join. |
![]() | JoinSetComposer | Interface for populating a join tuple result set from new data and old data for each stream. |
![]() | JoinSetIndicator | Marker interface for indicators to join set processors. |
![]() | JoinSetProcessor |
Processes a join result set constisting of sets of tuples of events.
|
![]() | QueryStrategy |
Encapsulates the strategy use to resolve the events for a stream into a tuples of events in a join.
