====== ConditionInstanceManager ======

**//Inherited from//**  [[class::domain::xmanager|XManager]],

**//Inherited by//**  NULL

**//Friend class//**  NULL

**//Description//**

ConditionInstanceManager从XManager继承，是条件实例对象管理器，所有条件实例对象的创建、销毁、访问以及修改都通过调用它的通用接口完成。它的域识别码是Domain_ConditionInstance，类型名是“DCNDINSTANCE”。

**//Public interface//**
  * [[conditioninstancemanager#conditioninstancemanager1|ConditionInstanceManager]](XMemPool * item_pool)
  * virtual [[conditioninstancemanager#~conditioninstancemanager|~ConditionInstanceManager]]()
  * void [[conditioninstancemanager#write|write]](XH5IO * io, H5Obj * grp)
  * bool [[conditioninstancemanager#read|read]](XH5IO * io, H5Obj * grp)
  * void [[conditioninstancemanager#serialize|serialize]](XBinaryIO * io, XItem * obj, bool bSave)
  * void [[conditioninstancemanager#updatecache|updateCache]](XItem * obj, OpnType opn)
