Now I've realised that there are two degrees of connectedness.
It is very much possible to have a "free standing" BusTerm, which
only allows to send uplink messages. In fact, this is how CoreService
is implemented, and probably it should also the way how to connect
the GuiNotification service...
Decision was made to use the CoreService as PImpl to organise
all those technical aspects of running the backbone. Thus,
the Nexus (UI-Bus hub) becomes part of CoreService
Damn sideeffect of the suppport for move-only types: since we're
moving our binding now into place /after/ construction, in some cases
the end() iterator (embedded in RangeIter) becomes invalid. Indeed this
was always broken, but didn't hurt, as long as we only used vectors.
Solution: use a dedicated init() hook, which needs to be invoked
*after* the TreeMutator has been constructed and moved into the final
location in the stack buffer.
the generic typing to DiffMutatble does not make much sense,
since the desired implementation within gui::ctrl::Nexus
is bound to work on Tangibles only, since that is what
the UI-Bus stores in the routing table
based on the previous experiments, this adds a fake operation
and a definition frame to hook this operation as pseudo Proc-Layer command
WIP: the invocation itself is not yet implemented.
We need to build a custom invocation pattern for that,
in order to be able to capture the instance-ID of the command
on invocation
NOTE: also, because of #989, we can not bind a time value for this test
I worked under the erroneous assumption, that Doxygen
will use its internal entity-IDs as the link-IDs when
generating mardown-links. Yes, this seemed logical and
this would be the way I'd implement it....
But seemingly, Doxygen is not so consistent when it
comes to questions of syntax. The same holds true for
markdown, which lacking a coherent definition anyway.
Another problem is that Doxygen's auto-link generation
frequently fails, for reasons not yet clear to me.
Sometimes it seems to be necessary to give it a nudge
by including the \ref command. While I'm not willing
to go into focussed invstigation of Doxygen syntax
right now, at least I've done a search-and-replace
to remove the malformed links I've written the
last days
at the point when we're connecting a new node to the UI-Bus,
the new node's BusTerm is not yet initialised, since we need
the uplink connection we're about to create for setting up
this BusTerm.
Consequently, the new nodes's ID is not yet initialised,
so we need to pass this endpoint-ID explicitly to the
registration function.
since, by definition, the Nexus is "the" up-link,
all we need is clever overriding of the relevant
handling functions, so the nexus will care for the routing,
while the CoreService cares for command and presentation
state handling
