ActivityEdge link notes support

[grivo]

prerequisites

as standard of UML 2.5 claims, ActivityEdge of an activity type diagram may have its own note attached due to some features existence

current ad-hoc

the only way now to attach a note to a link between activity nodes is a subdiagram, embraced by awkward whitespace and single character (i have used dot here) - it decreases the chance of overlapping between subdiagram and parent diagram's elements

here is an example

@startuml example

start

:read tasks;

->selecting my tasks;

:tasks
[open, running, failed, closed]; <<task>>
note right
    as UML standard says,
    //selection// annotation
    attached to an //ObjectNode//
    means base filtering and
    ordering, syntax may vary

    --<<selection>>--
    
    export non-closed tasks only 
end note

split
    ->my active tasks
    {{
        skinparam Backgroundcolor transparent

        note as _
            as UML standard says, //selection// annotation attached to an //ActivityEdge//
            means secondary filtering of tokens exported by an //ObjectNode// from
            above, syntax may vary
            
            --<<selection>>--

            process active (opened and running) tasks only 
        end note
    }}








    
                                                                                       .;
    
    :set tasks priority;
split again
    ->my failed tasks
    {{
        skinparam Backgroundcolor transparent

        note as _
            as UML standard says, //transformation// annotation attached to an //ActivityEdge//
            means tokens will be transformed somehow, syntax may vary
            
            --<<transformation>>--

            extract name of reporter from every task
        end note
    }}
    ;



    :reporters; <<task>>

    :have meeting with reporters of failed issues;
    
end split

:prepare tasks resolution schedule;

stop

request

ActivityEdge should have not support sort of

:action;

->my link;
note [left, top, bottom, right] on link
    text of the node
end note

:next action;
