You can dynamically update the rule chain at runtime, change the behavior and business logic of the rule chain, and achieve non-stop update and expansion of business logic.

• Update the root rule chain

err := ruleEngine.ReloadSelf([]byte(ruleFile))

• Update a node of the root rule chain

//Update the sub-rule chain
ruleEngine.ReloadChild(types.EmptyRuleNodeId, types.RuleNodeId{Id: "s1"}, []byte(modifyNodeFile))
