The <TT>attach-agent</TT> method can be used to attach an applicationto an agent, as follows:<PRE> set ftp1 [new Application/FTP] $ftp1 attach-agent $src</PRE><P>The following shortcut accomplishes the same result:<PRE> set ftp1 [$src attach-app FTP]</PRE><P>The attach-agent method, which is also used by attach-app, is implemented in C++. It sets the <TT>agent_</TT>pointer in <TT>class Application</TT> to point to the transport agent, and thenit calls <TT>attachApp()</TT> in <TT>agent.cc</TT> to set the <TT>app_</TT> pointerto point back to the application. By maintaining this binding only in C++,OTcl-level instvars pointers are avoided and consistency between OTcl and C++ is guaranteed. The OTcl-level command <TT>[$ftp1 agent]</TT> can be used by applications to obtain the handler for the transport agent.<P><BR><HR><ADDRESS>2003-09-23</ADDRESS></BODY></HTML>⌨️ 快捷键说明
