Class OrderedProperties

java.lang.Object

java.util.Dictionary<K,V>

java.util.Hashtable<Object,Object>

java.util.Properties

com.ctrip.framework.apollo.util.OrderedProperties

All Implemented Interfaces:

Serializable, Cloneable, Map<Object,Object>

public class OrderedProperties
extends Properties

An OrderedProperties instance will keep appearance order in config file. Warnings: 1. It should be noticed that stream APIs or JDk1.8 APIs( listed in https://github.com/ctripcorp/apollo/pull/2861) are not implemented here. 2. Properties implementation are different between JDK1.8 and later JDKs. At least, Properties have an individual implementation in JDK10. Hence, there should be an individual putAll method here.
