Examples of org.drools.common.RuleFlowGroupImpl$DeactivateCallback

org.drools.common.RuleFlowGroupImpl
Implementation of a RuleFlowGroup that collects activations of rules of this ruleflow-group. If this group is activated, all its activations are added to the agenda. As long as this group is active, its activations are added to the agenda. Deactivating the group removes all its activations from the agenda and collects them until it is activated again. By default, RuleFlowGroups are automatically deactivated when there are no more activations in the RuleFlowGroup. However, this can be configured.


        while (stream.readShort() == PersisterEnums.RULE_FLOW_GROUP) {
            String rfgName = stream.readUTF();
            boolean active = stream.readBoolean();
            boolean autoDeactivate = stream.readBoolean();
            RuleFlowGroupImpl rfg = new RuleFlowGroupImpl( rfgName,
                                                           active,
                                                           autoDeactivate );
            agenda.getRuleFlowGroupsMap().put( rfgName,
                                               rfg );
            int nbNodeInstances = stream.readInt();
            for (int i = 0; i < nbNodeInstances; i++) {
                Long processInstanceId = stream.readLong();
                String nodeInstanceId = stream.readUTF();
                rfg.addNodeInstance( processInstanceId,
                                     nodeInstanceId );
