#<(other) ⇒ Object

call-seq: mod < other -> true, false, or nil

Returns true if mod is a subclass of other. Returns nil if there’s no relationship between the two. (Think of the relationship in terms of the class definition: “class A < B” implies “A < B”.)

def <(other)
  if self.equal?(other)
    false
  else
    self <= other
  end
end

#<=(other) ⇒ Object

call-seq: mod <= other -> true, false, or nil

Returns true if mod is a subclass of other or is the same as other. Returns nil if there’s no relationship between the two. (Think of the relationship in terms of the class definition: “class A < B” implies “A < B”.)

def <=(other)
  raise TypeError, 'compared with non class/module' unless other.is_a?(Module)
  if self.ancestors.include?(other)
    return true
  elsif other.ancestors.include?(self)
    return false
  end
end

#<=>(other) ⇒ Object

call-seq: module <=> other_module -> -1, 0, +1, or nil

Comparison—Returns -1, 0, +1 or nil depending on whether module includes other_module, they are the same, or if module is included by other_module.

Returns nil if module has no relationship with other_module, if other_module is not a module, or if the two values are incomparable.

  return -1 if cmp

end

#>(other) ⇒ Object

call-seq: mod > other -> true, false, or nil

Returns true if mod is an ancestor of other. Returns nil if there’s no relationship between the two. (Think of the relationship in terms of the class definition: “class A < B” implies “B > A”.)

end

#>=(other) ⇒ Object

call-seq: mod >= other -> true, false, or nil

Returns true if mod is an ancestor of other, or the two modules are the same. Returns nil if there’s no relationship between the two. (Think of the relationship in terms of the class definition: “class A < B” implies “B > A”.)
