Instance Method Details

#from_hash(properties_hash, property_order) ⇒ Object

Does the same job as Entity.from_hash except of the following differences:

  1. unknown properties from the properties_hash are stored to additional_data of the relayable instance
  2. parent entity fetch is attempted
  3. signatures verification is performed; property_order is used as the order in which properties are composed to compute signatures
  4. unknown properties' keys must be of String type

def from_hash(properties_hash, property_order)
  # Use all known properties to build the Entity (entity_data). All additional elements
  # are respected and attached to a hash as string (additional_data). This is needed
  # to support receiving objects from the future versions of diaspora*, where new elements may have been added.
