Functions

add(Name, Data)

-spec add(name(), any()) -> ok.

See also: add/3.

add(Name, Pid, Data)

-spec add(name(), pid(), any()) -> ok.

Adds the current process data. Usually called in the start/2 callback of an amoc scenario.

notify(Name, Event)

-spec notify(name(), coordinator_timeout | reset_coordinator | {coordinate, {pid(), term()}}) -> ok.

reset(Name)

-spec reset(name()) -> ok.

Resets a coordinator, that is, calls all coordination actions with reset as the coordination data.

start(Name, CoordinationPlan)

-spec start(name(), plan()) -> ok | error.

See also: start/3.

start(Name, CoordinationPlan, Timeout)

-spec start(name(), plan(), coordination_timeout_in_sec()) -> ok | error.

Starts a coordinator. Usually called in the init callback of an amoc scenario.

stop(Name)

-spec stop(name()) -> ok.

Stops a coordinator.
