Instance Method Details

def context(a_context)
  @statemachine.context = a_context
  a_context.statemachine = @statemachine if a_context.respond_to?(:statemachine=)
end

#stub_context(options = {}) ⇒ Object

Stubs the context. This makes statemachine immediately useable, even if functionless. The stub will print all the actions called so it’s nice for trial runs.

sm = Statemachine.build do
  ...
  stub_context :verbose => true
end

Statemachine.context may also be used.
