`class Name`

Extensions to the Resolv::DNS::Name class.

Definitions

`def with_origin(origin, absolute = true)`

Computes the name, typically absolute, with the specified origin as a suffix. If the origin is nil, don't change the name, but change it to absolute (as specified).

Signature

parameter　origin　Array | String: The origin to append to the name.
parameter　absolute　Boolean: If true, the name will be made absolute.

Implementation

def with_origin(origin, absolute = true)
	return self.class.new(@labels, absolute) if origin == nil
	
	origin = Label.split(origin) if String === origin
	
	return self.class.new(@labels + origin, absolute)
end

`def without_origin(origin, absolute = false)`

Compute the name, typically relative, without the specified origin suffix. If the origin is nil, don't change the name, but change it to absolute (as specified).

Signature

parameter　origin　Array | String: The origin to remove from the name.
parameter　absolute　Boolean: If true, the name will be made absolute.
raises　OriginError: If the name does not end with the specified origin.

Implementation

def without_origin(origin, absolute = false)
	return self.class.new(@labels, absolute) if origin == nil
	
	origin = Label.split(origin) if String === origin
	
	if @labels.last(origin.length) == origin
		return self.class.new(@labels.first(@labels.length - origin.length), absolute)
	else
		raise OriginError.new("#{self} does not end with #{origin.join('.')}")
	end
