--------------------------------------------------------------
[~yunta] Thanks you very much.
For example， I have different rules for every device ，but I don’t want compile the rule repeatly. So I keep it in keyed state ,but the RuleEvaluator maybe not serializable.
{code:java}
public Class PojoClass
{
public RuleDescription[] rules;
public transient RuleEvaluator[] evaluators;
}
{code}
