implements SingleValueKnowledgeBaseOption

An Enum for Left & Right Unlinking option.

 drools.lrUnlinkingEnabled = <true|false>
 
DEFAULT = false.

Left & Right unlinking is a RETE optimization that leads to improvements in performance and memory consumption, mainly for large rule bases. It is still an experimental feature in Drools and not active by default. For further details, have look at this blog entry.
