|
* execution plan for pulling a specific exit node.
|
|
* Usable as blue print for generating actual render jobs.
|
|
* Job tickets are created on demand, specialised for each segment
|
|
* of the low-level model, and for each individual feed (corresponding
|
|
* to a single model port). Once created, they are final for this segment,
|
|
* stored together with the other descriptor objects (ProcNode and WiringDescriptor)
|
|
* and finally discarded in bulk, in case that segment of the low-level model becomes
|
|
* obsolete and is replaced by a newly built new version of.
|
|
*
|
|
* Job tickets are created by a classical recursive descent call on the exit node,
|
|
* which figures out everything to be done for generating data from this node.
|
|
* To turn a JobTicket into an actual job, we need the additional information
|
|
* regarding the precise frame number (=nominal time) and the channel number
|
|
* to calculate (in case the actual feed is multichannel, which is the default).
|
|
* This way, the JobTicket acts as <i>higher order function:</i> a function
|
|
* generating on invocation another, specific function (= the job).
|
|
*
|
|
* @todo 1/12 WIP-WIP-WIP defining the invocation sequence and render jobs
