注解

业务逻辑处理器通过调用 RegisterBusinessLogicHandler来注册。 在调用RegisterBusinessLogicHandler之前，必须先设置好对象的BusinessLogicHandler属性。

业务逻辑处理程序的注册通过调用 UnregisterBusinessLogicHandler来移除。

调用 EnumBusinessLogicHandlers 以获取服务器上注册的业务逻辑处理器列表。

构造函数

名称 说明
BusinessLogicHandler()

初始化 BusinessLogicHandler 类的新实例。

属性

名称 说明
DotNetAssemblyName

获取或设置实现业务逻辑处理器的汇编名称。
DotNetClassName

获取或设置实现业务逻辑处理器的类名称。
FriendlyName

获取或设置服务器上注册业务逻辑处理器的名称。
IsDotNetAssembly

获取或设置一个值，指示注册的业务逻辑处理器是否为托管代码汇编。
UserData

获取或设置一个对象，用户可以附加自己的数据。

方法

名称 说明
CheckValidDefinition(Boolean)

表示该定义是否有效。
