(事件名称 。callback_function)

• 事件名称是以下外部参照反应器事件之一：

  外部参照反应器事件
  事件名称	描述
  ：VLR-开始附加	即将附加外部参照。
  ：VLR-其他附加	正在将外部参照添加到图形数据库中。此事件发生在克隆对象之后，但在任何转换之前。此回调函数紧随其后发送，但仅在外部参照连接过程中发生。beginDeepCloneXlation notification
  ：VLR-中止附加	外部参照附着操作在成功完成之前已终止。
  ：VLR-endAttach	外部参照附着操作已成功完成。
  ：VLR重定向	正在修改外部参照图形中的对象 ID，以指向正在参照的图形中的关联对象。
  ：VLR通信	对象的对象 ID 将追加到要外部参照的图形的符号表中。
  ：VLR-开始恢复	即将解析现有外部参照（通常在加载具有外部参照的图形时）。
  ：VLR-中止恢复	外部参照卸载或重新加载在成功完成之前已终止。
  ：VLR-endRestore	已解析现有外部参照（通常在具有外部参照的图形完成加载时）。
  ：VLR-xrefSubcommandBindItem	已调用外部参照的 BIND 子命令，或者正在绑定预先存在的外部参照。 注意：BIND 子命令是交互式的，可触发多个事件。
  ：VLR-xrefSubcommandAttachItem	已调用外部参照的 ATTACH 子命令，或者正在解析先前存在的外部参照。 注意：附加子命令是交互式的，可触发多个事件。
  ：VLR-外部参照子命令覆盖项	已调用外部参照的叠加子命令，或者正在解析预先存在的外部参照。 注意：OVERLAY 子命令是交互式的，可触发多个事件。
  ：VLR-xrefSubcommandDetachItem	外部参照的 DETACH 子命令被调用。 注意：DETACH 子命令是交互式的，可触发多个事件。
  ：VLR-xrefSubcommandPathItem	外部参照的 PATH 子命令被调用。 Note: The PATH subcommand is interactive and triggers multiple events.
  :VLR-xrefSubcommandReloadItem	The RELOAD subcommand of XREF was invoked, or a preexisting xref is being reloaded. Note: The RELOAD subcommand is interactive and triggers multiple events.
  :VLR-xrefSubcommandUnloadItem	The UNLOAD subcommand of XREF was invoked, or a preexisting xref is being unloaded.

• callback_function is a symbol representing a function to be called when the event fires. Each callback function accepts two arguments:

  reactor_object -- The VLR object that called the callback function.

  list -- A list of extra data elements associated with the particular event. The contents of this list for particular events are shown in the “XREF reactor callback data” table.
