XACLI – Special Commands – xfeedback (I)
About the TANDBERG API
The special command xfeedback lets the user
register user defined XPath expressions (with pos-
sible exposure options) to monitor changes in the
XML/XACLI data. Whenever there is a change in
one or more elements addressed by a registered
XPath expression, the part of the element struc-
ture containing these changes will be returned.
The system supports a total of 20 registered
expressions, with a total of 15 expressions for one
RS 232/Telnet session.
The xfeedback is a session specific command,
i.e. different RS 232/Telnet session can define
feedback individually.
This also implies that the feedback expressions
must be set each time the control application
connects to the codec, i.e. the control application
should always set the necessary feedback expres-
sions when connecting to the system (or after
system reboot when using RS 232).
