                    throws ExprValidationException

Compiles a raw stream specification consisting event type information and filter expressions to an validated, optimized form for use with filter service

Parameters:

statementContext - statement-level services

eventTypeReferences - event type names used by the statement

isInsertInto - true for insert-into

isJoin - indicates whether a join or not a join

isContextDeclaration - indicates whether declared as part of the context declarations, if any

isOnTrigger - indicator for on-trigger

optionalStreamName - stream name

assignedTypeNumberStack - for assigning nested type numbers

Returns:

compiled stream

Throws:

ExprValidationException - to indicate validation errors
