Synopsis
require 'identifier/uuid'
uuid = Identifier::UUID::Random.get
# => "df95804e-02fc-490a-a946-e7304942b09e"
string = "My UUID v4 is: #{uuid}"
Identifier::UUID.parse(string)
# => "df95804e-02fc-490a-a946-e7304942b09e"
Identifier::UUID.uuid?('df95804e-02fc-490a-a946-e7304942b09e')
# => true
Identifier::UUID.uuid?('something')
# => falseDependency Configuration
This library was written according to The Doctrine of Useful Objects. As such, it can be configured as either :identifer or :uuid, and has a useful inert substitute.
require 'identifier/uuid'
class MyClass
dependency :identifier, Identifier::UUID::Random
def self.build
instance = new
Identifier::UUID::Random.configure(instance)
instance
end
end
instance = MyClass.new
instance.identifier.get # nil
instance.identifier.set("my string")
instance.identifier.get # "my string"
operational = MyClass.build
operational.identifier.get # "df95804e-02fc-490a-a946-e7304942b09e"License
