Message relay based on ns_connchan

Defined in packages/xotcl-core/tcl/message-relay-procs.tcl

Class Relations

• class: ::xo::MessageRelay

Methods (to be applied on the object)

• can_be_used (scripted, public)

   xo::mr::connchan can_be_used

  ns_connchan can be used on every recent NaviServer.

  Testcases:

  No testcase defined.

• send_to_subscriber (scripted, public)

   xo::mr::connchan send_to_subscriber key msg

  Write directly to the subscribers from the connection thread via ns_connchan. It would be possible, to perform asynchronous operations via "ns_connchan callback", which would be handled in the background. Not sure, this is necessary.

  Parameters:

  key (required)

  msg (required)

  Testcases:

  No testcase defined.

• subscribe (scripted, public)

   xo::mr::connchan subscribe [ -initmsg initmsg ] [ -mode mode ] key

  ns_log notice "#### [self] subscribe $key mode $mode" Unplug the connection channel from the current connection thread. The currently unplugged channels can be queried via "ns_connchan list"

  Switches:

  -initmsg (optional)

  -mode (optional)

  Parameters:

  key (required)

  Testcases:

  No testcase defined.

• sweep (scripted, public)

   xo::mr::connchan sweep key

  For the time being, do nothing. Since the chat is verbose on logins/logouts, write operations will fail, in which case the array is cleaned up. If this is not sufficient, probably a "ns_connchan eof" operation would be useful.

  Parameters:

  key (required)

  Testcases:

  No testcase defined.
