Instance Method Details

#pick_fields(*keys) ⇒ Object

Return a hash table representation of ourselves, with the key equal to the @node.name, and the value equal to the fields specified in *keys.

Also, the result is flattened to a single hash, so a key of ‘a.b’ becomes ‘a_b’

compare to Object#pick(*keys). This method is the sames as Config::ObjectList#pick_fields, but works on a single node.

Example:

node.pick('domain.internal') =>

  {
    'node1': {
      'domain_internal': 'node1.example.i'
    }
  }

end
