Examples of org.drools.common.TruthMaintenanceSystem

org.drools.common.TruthMaintenanceSystem
The Truth Maintenance System is responsible for tracking two things. Firstly It maintains a Map to track the classes with the same Equality, using the EqualityKey. The EqualityKey has an internal datastructure which references all the handles which are equal. Secondly It maintains another map tracking the justificiations for logically asserted facts.
