This interface extends interface IKCmdOps by providing access to
notification suspension for the IK system.
This class contains functionality for suspending and resuming IK
system notification and for inquiring its status. If you have a
large number of node parenting, you can expect a performance gain
if you suspend IK link notifications. Be sure to match any call to
SuspendLinkNotify()
with one to ResumeLinkNotify()
since they are nestable. You get this interface by calling
