Mac OS X Leopard与目录服务(AD/OD)集成宝典(9)

9.扩展记录扩展记录是在Leopard的OD中引入的概念.正如这个名字隐含的,扩展记录是在另一个引入的记录上添加了信息的记录.扩展记录允许实施一个本来在前面目录服务中没有的记录应用到一个用户记录.这一点对主目录服务器没有扩展架构权限的管理很有用.为了实施扩展记录,要把主OD绑定到根目录服务,把对象从根目录引入,然后用MacOSX特殊的属性增加到引入的记录上,比如MCX设置,IMHandle和WeblogURI等.MacOSX客户被绑定到主OD和其它的目录服

ESBasic 可复用的.NET类库（14）－－优先级管

1.缘起：假设我们的订单处理系统所要处理的订单是有优先级的，也就是说，不同的订单类型所要求被处理的紧迫程度不同，对那些优先级高的注单要先处理，对于优先级低的注单可稍后处理。对于处于同一优先级的订单了，就按照其到达的先后顺序进行处理。这是一个典型的管理具有优先级的对象的需求，注单就是具有优先级（WithPriority）的对象。我设计了ESBasic.ObjectManagement.Managers.IPriorityManager优先级管理器（确切地说，
