6822a9e2fb DOC: reorganise the Doxygen configuration and structure
- upgrade the configuration to a current version
- provide a frontpage with cross-links to other documentation
- define a set of modules; relevant classes and files can be
  added to these, to create a exploration path for new readers
- fix a lot of errors in documentation comments
- use a custom configuration for the documentation pages
- tweak the navigation, the sections and further arrangements

974c670d41 fix **** in doxygen comments
to make them stand out more prominently, some entity comments
where started with a line of starts. Unfortunately, doxygen
(and javadoc) only recogise comments which are started exactly
with /**

This caused quite some comments to be ignored by doxygen.
Credits to Hendrik Boom for spotting this problem!

A workaround is to end the line of stars with *//**

a344604f1b Clang(#928): adjustments regarding scope and visibility
Clang doesn't allow to declare a private nested class as friend.
This is unfortunate, but likely correct to the letter of the standard.

As a workaround, now we're creating the instances within a static
function of DependencyFactory -- in the end this improves readability


A second issue fixed with this changeset is the scope of the
marker function. Clang is right, this isn't ADL, thus an inline
friend definition is simply not visible outside the class.

0ea37402d2 Ticket #934: switch entire code-base to use the new Singleton factory
lib::Depend<TY>  works as drop-in replacement for lib::Singleton<TY>

This changeset removes the convoluted special cases like
SingletonSub and MockInjector.

4ea20f0e74 Clang(#928): fix inconsistencies and compilation problems
Compilation with Clang 3.0 (which is available in Debian/stable) fails,
mostly due to some scoping and naming inconsistencies which weren't detected
by GCC. At some instances, Clang seems to have problems to figure out a
perfectly valid type definition; these can be resolved by more explicit
typing (which is preferrable anyway)

febce1282c standard hash value for jobs (prerequisite for #786)
this is mostly a diagnostic facility; the actual scheduling
of jobs doesn't rely on hash values.

77066ee3ce WIP: how to start the actual calculation streams within EngineService
this draft fills in the structure how to get from an invocation
of the engine service to the starting of actual CalcStream instances.

Basically the EngineService implementation is repsonsile to
instruct the Segmentation to provide a suitable Dispatcher.

723096d3f2 WIP introduce a new kind of job closure to perform the planning
this might help solving that gordian knot related to the TimeAnchor,
the Dispatcher and the introduction of a possible playback strategy
2013-06-02 03:09:18 +02:00
082822fde8 relocate the JobClosure interface to be defined alongside of Job
This is necessary since the implementation of the job functions
calls through the VTable of the interface JobClosure. Thus this
interface (and the VTable definition) needs to reside within
some compilation unit linked together with the basic job class.

TODO: move class Job entirely into the Backend

8982223a4d pondering about a suitable definition of a planning chunk (#920)
mostly this seems to be a matter of getting the terms

25be40bb4a change PlanningStepGenerator end-of-sequence logic
basically I've changed my mind to prefer an
infinite JobPlanningSequence, which is just
evaluated partially. This removes the need to
embody the logic of planning chunk generation,
which really is a different concern.

18605b0c19 handling of real time start offset
decision: the base for any deadline calculations
is the expected real time corresponding to the grid origin.
This value is contained in the Timings record.
2013-01-12 08:36:35 +01:00
72e5557d1e locate the real time / nominal within engine::TimeAnchor
this clarifies the relation of TimeAnchor and Timings,
the latter act as a general spec and abstracted grid,
while the latter actually performs the conversion and
deadline checking

44435fd1db clarify and settle the relation between Dispatcher and PlanningStepGenerator
the solution is to introduce a superinterface
and let Dispatcher augment that with the specific parts.
This way, the Job planning only has to rely on the
rather generic stuff (TimeAnchor, FrameCoord)

NOTE: this commit makes the whole JobPlanning machinery
compilable for the first time!

3300d00cc8 WIP working towards a solution for generating frame location sequences
..the Idea is to rely on some kind of service,
to break the cyclic dependency with the Dispatcher.
But I seem unable to find a natural location or
concept to house that service.

involved templates, i.e. get the complete
pipeline definition through the compiler
2012-10-10 05:20:22 +02:00
b52a1a8366 refactor JobTicket to remove the double layering
basically we had two lines of doubly nested capsules, due to
using the IterAdaptor template. Actually, the evaluation stack
within JobTicket can be considered an implementation detail and
thus doesn't require an iterator interface; the intention is to
use this through JobPlanning solely.

Thus this reworking removes the special iterator within JobTicket,
but retains the idea of exposing the "current" JobTicket through
a smart pointer or  operator->()

work done during the FrOSCon travel
2012-10-10 05:20:21 +02:00
66defdc0cb refactor JobPlanning to encapsulate all state mechanics into a "state core"
especially the exploration stack is pushed down
first successful definition of all the JobPlanning classes

just the framework of classes necessary to pass the compiler;
all implementation is still stubbed

a3bc69cc77 maybe a breakthrough on the job planning design quest?
why the hell is getting this design about right
such a chellenging task. Anyway, seems to be the
first step ahead after numerous failed attempts
2012-10-10 05:20:21 +02:00
016a739a5c WIP back to the original problem: how to dispatch jobs...
brainstorming how to implement the job planning stage

the idea is to built on top of the IterExplorer,
but have the "stack" of re-evaluation integrated
into a custom type, which exploits the static
node network structure to avoid heap allocations

solution idea: again use a builder function?
