Interface Summary

JoinExecTableLookupStrategy

Strategy for looking up, in some sort of table or index, an event, potentially based on the events properties, and returning a set of matched events.

Class Summary

CompositeTableLookupStrategy	Lookup on an nested map structure that represents an index for use with at least one range and possibly multiple ranges and optionally keyed by one or more unique keys.
ExecNode	Interface for an execution node that looks up events and builds a result set contributing to an overall join result set.
ExecNodeNoOp
FullTableScanLookupStrategy	Lookup on an unindexed table returning the full table as matching events.
FullTableScanUniqueValueLookupStrategy	Lookup on an unindexed table returning the full table as matching events.
HistoricalDataExecNode	Execution node for executing a join or outer join against a historical data source, using an lookup strategy for looking up into cached indexes, and an indexing strategy for indexing poll results for future lookups.
HistoricalTableLookupStrategy	A lookup strategy for use in outer joins onto historical streams.
IndexedTableLookupStrategy	Lookup on an index using a set of properties as key values.
IndexedTableLookupStrategyExpr	Lookup on an index using a set of expression results as key values.
IndexedTableLookupStrategySingle
IndexedTableLookupStrategySingleExpr
InKeywordMultiTableLookupStrategyExpr	Lookup on an index using a set of expression results as key values.
InKeywordSingleTableLookupStrategyExpr	Lookup on an index using a set of expression results as key values.
LookupInstructionExec	Execution for a lookup instruction to look up in one or more event streams with a supplied event and using a given set of lookup strategies, and adding any lookup results to a lighweight repository object for later result assembly.
LookupInstructionExecNode	Execution for a set of lookup instructions and for a set of result assemble instructions to perform joins and construct a complex result.
LookupInstructionExecNode.MyResultAssembler	Receives result rows posted by result set assembly nodes.
NestedIterationExecNode	Execution node that performs a nested iteration over all child nodes.
RangeIndexLookupValue
RangeIndexLookupValueEquals
RangeIndexLookupValueRange
SortedTableLookupStrategy	Lookup on an index that is a sorted index on a single property queried as a range.
TableLookupExecNode	Execution node for lookup in a table.
TableLookupExecNodeTableLocking	Execution node for lookup in a table.
