Description
Interface Summary | |
---|---|
EngineImportService | Service for engine-level resolution of static methods and aggregation methods. |
MethodResolutionService | Service for resolving methods and aggregation functions, and for creating managing aggregation instances. |
OrderByProcessor | A processor for ordering output events according to the order specified in the order-by clause. |
ResultSetProcessor | Processor for result sets coming from 2 sources. |
SelectExprProcessor | Interface for processors of select-clause items, implementors are computing results based on matching events. |
StreamTypeService | Service supplying stream number and property type information. |
ViewResourceCallback | Callback for use by expression nodes to receive view resources. |
ViewResourceDelegate | Service to expression nodes for indicating view resource requirements. |
Class Summary | |
---|---|
AliasNodeSwapper | A utility class for replacing select-clause aliases with their definitions in expression node trees. |
EngineImportServiceImpl | Implementation for engine-level imports. |
EngineSettingsService | Service for engine-level settings around threading and concurrency. |
MethodPollingExecStrategy | Viewable providing historical data from a database. |
MethodPollingViewable | Polling-data provider that calls a static method on a class and passed parameters, and wraps the results as POJO events. |
MethodPollingViewableFactory | Factory for method-invocation data provider streams. |
MethodResolutionServiceImpl | Implements method resolution. |
OrderByProcessorFactory | Factory for OrderByProcessor processors. |
OrderByProcessorSimple | An order-by processor that sorts events according to the expressions in the order_by clause. |
PropertyResolutionDescriptor | Encapsulates the result of resolving a property and optional stream name against a supplied list of streams
StreamTypeService . |
ResultSetAggregateAllIterator | Iterator for aggregation results that aggregate all rows. |
ResultSetAggregateGroupedIterator | Iterator for group-by with aggregation. |
ResultSetProcessorAggregateAll | Result set processor for the case: aggregation functions used in the select clause, and no group-by, and not all of the properties in the select clause are under an aggregation function. |
ResultSetProcessorAggregateGrouped | Result-set processor for the aggregate-grouped case: there is a group-by and one or more non-aggregation event properties in the select clause are not listed in the group by, and there are aggregation functions. |
ResultSetProcessorFactory | Factory for output processors. |
ResultSetProcessorRowForAll | Result set processor for the case: aggregation functions used in the select clause, and no group-by, and all properties in the select clause are under an aggregation function. |
ResultSetProcessorRowPerGroup | Result set processor for the fully-grouped case: there is a group-by and all non-aggregation event properties in the select clause are listed in the group by, and there are aggregation functions. |
ResultSetProcessorSimple | Result set processor for the simplest case: no aggregation functions used in the select clause, and no group-by. |
ResultSetProcessorSimple.ResultSetSimpleTransform | Method to transform an event based on the select expression. |
ResultSetRowPerGroupIterator | Iterator for the group-by case with a row per group. |
SelectExprEvalProcessor | Processor for select-clause expressions that handles a list of selection items represented by expression nodes. |
SelectExprEvalProcessorStreams | Processor for select-clause expressions that handles a list of selection items represented by expression nodes. |
SelectExprJoinWildcardProcessor | Processor for select-clause expressions that handles wildcards. |
SelectExprProcessorFactory | Factory for select expression processors. |
StreamTypeServiceImpl | Implementation that provides stream number and property type information. |
ViewResourceDelegateImpl | Coordinates between view factories and requested resource (by expressions) the availability of view resources to expressions. |
Exception Summary | |
---|---|
DuplicatePropertyException | Indicates a property exists in multiple streams. |
EngineImportException | Indicates a problem importing classes, aggregation functions and the like. |
EngineImportUndefinedException | Indicates a problem importing classes, aggregation functions and the like. |
PropertyNotFoundException | Exception to indicate that a property name used in a filter doesn't resolve. |
StreamNotFoundException | Exception to indicate that a stream name could not be resolved. |
StreamTypesException | Base class for stream and property name resolution errors. |
Contains EQL statement specification classes define the constructs that make up an EQL statement, such as the list of items in the select clause, the insert-into stream name and property names etc.
