Constant Summary collapse

UNLISTEN_WRAPPER_TYPE =

Redefining this constant would allow you to set whatever unlisten wrapper you want

{
    unlisten_wrapper_with_termination: "CelluloidIOPGListener::UnlistenWrappers::WithTermination",
    unlisten_wrapper_without_termination: "CelluloidIOPGListener::UnlistenWrappers::WithoutTermination"
}
VERSION = 
"0.3.2"

Class Method Summary collapse

Class Method Details

.client(unlisten_wrapper_type = :unlisten_wrapper_with_termination) ⇒ Object

Returns a module Usage:

class MyClient
  include CelluloidIOPGListener.client(:unlisten_wrapper_with_termination) # with no argument this is default
end

For a Client that will be used inside a SupervisorContainer you want to let the Supervisor handle termination.

At least that's my operating hypothesis, if anyone knows better please let me know.

class MyClient
  include CelluloidIOPGListener.client(:unlisten_wrapper_without_termination)
end
