receiverName - the next receiver

relationA - the left relation

relationB - the bottom relation

msg - an additional message (might be null)

Throws:

IOException

EDBException

reasoning process and cannot be accessed after this method returns.

Specified by:

postJoin in interface ReasoningMonitor

Parameters:

rule - the rule

literal - the body literal

operatorName - the operator
