Method: PDK::Config::Setting#previous_setting=

Defined in:
lib/pdk/config/setting.rb

#previous_setting=(value) ⇒ Object (writeonly)

It is possible to have multiple setting definitions for the same setting; for example, defining a default value with a lambda, but the the validation is within a JSON schema document. These are expressed as two settings objects, and uses a single linked list to join them together:

(PDK::Config::JSONSchemaSetting) –previous_setting–> (PDK::Config::Setting)

So in the example above, calling default the on the first object in the list will:

  1. Look at default on PDK::Config::JSONSchemaSetting

  2. If a default could not be found then it calls default on previous_setting

  3. If a default could not be found then it calls default on previous_setting.previous_setting

  4. and so on down the linked list (chain) of settings
