Instance Method Details

#const_missing(const) ⇒ Object

def const_missing(const)
  init if [:Actor, :Commit, :Repository].include?(const)
  super unless const_defined? const
  const_get const
end

#init ⇒ Object

This initializes the VCS's implementation Module

This requires the Actor, Commit and Repository classes for that VCS implementation.
