Participants list

[Amedeo]

Hello,

We are trying to retrieve the list of all participants involved (or potentially involved) in a process. Is there any api or way to retrieve this list?

Thanks

Hello Amedeo,

no, but would something like (https://gist.github.com/3040131) this help?

---8<---
require 'pp'
require 'ruote'

pdef = Ruote.define do
alice
concurrence do
bob
charly
end
participant :ref => 'doug'
end

dboard = Ruote::Dashboard.new(Ruote::HashStorage.new)

dboard.register do
alice Ruote::NoOpParticipant
participant /.+/, Ruote::StorageParticipant
end

def find_participants(dboard, tree, accu=[])

if tree[0] == 'participant'
accu << [ tree[1]['ref'], dboard.participant(tree[1]['ref']).class ]
elsif exp_class = dboard.context.expmap.expression_class(tree[0])
# do nothing
elsif pa = dboard.participant(tree[0])
accu << [ tree[0], pa.class ]
end

tree[2].each do |t|
find_participants(dboard, t, accu)
end

accu
end

pp find_participants(dboard, pdef)
