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.
The following tables list the members exposed by the PatternStreamSpec type.
