Description copied from interface: StreamSpecRaw

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

Specified by:

compile in interface StreamSpecRaw

Parameters:

context - 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

Returns:

compiled stream

Throws:

ExprValidationException - to indicate validation errors
