<pre>//the process of issuing a session command from the UI//
Within the Lumiera UI, we distinguish between core concerns and the //local mechanics of the UI.// The latter is addressed in the usual way, based on a variation of the [[MVC-Pattern|http://en.wikipedia.org/wiki/Model%E2%80%93view%E2%80%93controller]]. The UI toolkit set, here the GTK, affords ample ways to express actions and reactions within this framework, where widgets in the presentation view are wired with the corresponding controllers vice versa (GTK terms these connections as //&quot;signals&quot;//, we rely on {{{libSigC++}}} for implementation).
A naive approach would extend these mature mechanisms to also cover the actual functionality of the application. This compelling solution allows quickly to get &quot;something tangible&quot; up and running, yet -- on the long run -- inevitably leads to core concerns being tangled into the presentation layer, which in turn becomes hard to maintain and loaded with &quot;code behind&quot;. Since we are here &quot;for the long run&quot;, we immediately draw the distinction between UI mechanics and core concerns. The latter are, by decree and axiom, required to perform without even an UI layer running. This decision gives rise to the challenge how to form and integrate the invocation of ''core commands'' into the presentation layer.

!command invocation protocol
* at start-up, command definitions are created in Proc, hard wired

* when command usage is indicated, some part in the UI queries the {{{CmdAccess}}} for an InteractionState
* the latter in turn retrieves a new command instance ID from the {{{CmdInstanceManager}}} in Proc
* and the latter keeps a smart-ptr corresponding to this instance in its internal registration table
* within the UI, a command instance corresponds to a specific invocation trail, and is thus stored within the managing {{{InteractionState}}}

* when a command is completely parametrised, it can be invoked. The managing {{{InteractionState}}} knows about this

* ~UI-Elements know the basic ~Command-IDs relevant to their functionality. These are &amp;rarr; [[defined in some central header|CommandSetup]]

*;context bound
*:invocation of a command is formed within a context, typically through a //interaction gesture.//
*:most, if not all arguments of the command are picked up from the context, based on the current [[Spot]]
*:* on setup of such an invocation context, the responsible part in the UI queries the {{{CmdAccess}}} for an InteractionState
*:* the latter in turn retrieves a new command instance ID from the {{{CmdInstanceManager}}} in Proc

An immediate consequence is that command instances will be formed //per instance// of InteractionState. Each distinct kind of control system has its own instances, which are kept around, until they are ready for invocation. Each invocation &quot;burns&quot; an instance -- on next access, a new instance ID will be allocated, and the next command invocation cycle starts...

Command instances are like prototypes -- thus each additional level of differentiation will create a clone copy and decorate the basic command ID. Yet this extension process is delegated into multiple stages. Already when a specific InvocationTrail is established, the bare command prototype is specialised, and additionally combined with specific context access rules and maybe even a accessor to retrieve some argument value. The {{{CmdInstanceManager}}} internally maintains and tracks a prepared anonymous command instance within a local registration table. The //smart-handle//-nature of command instance is enough to keep concurrently existing instances apart; instances might be around for an extended period, because commands are enqueued with the ProcDispatcher.
Command instances are like prototypes -- thus each additional level of differentiation will create a clone copy and decorate the basic command ID. This is necessary, since the same command may be used and parametrised differently at various places in the UI.
