Classes
Class | Description | |
---|---|---|
![]() | DBStatementStreamSpec | Specification object for historical data poll via database SQL statement. |
![]() | FilterStreamSpec | Specification for building an event stream out of a filter for events (supplying type and basic filter criteria)
and views onto these events which are staggered onto each other to supply a final stream of events.
|
![]() | InsertIntoDesc | Descriptor generated by INSERT-INTO clauses specified in expressions to insert the

|
![]() | OuterJoinDesc | Contains the ON-clause criteria in an outer join. |

![]() | PatternStreamSpec | Specification for building an event stream out of a pattern statement and views staggered onto the
pattern statement.
The pattern statement is represented by the top EvalNode evaluation node. A pattern statement contains tagged events (i.e. a=A -> b=B). Thus the resulting event type is has properties "a" and "b" of the type of A and B. |
![]() | SelectExprElementNamedSpec | Represents a single item in a SELECT-clause, with a name assigned
either by the engine or by the user specifying an "as" tag name.
|
![]() | SelectExprElementUnnamedSpec | Represents a single item in a SELECT-clause, potentially unnamed
as no "as" tag may have been supplied in the syntax.
Compare to net.esper.eql.spec.SelectExprElementNamedSpec which carries a determined name. |

Specification object representing a complete EQL statement including all EQL constructs.
|
![]() | StreamSpec |
