#init_data ⇒ Hash readonly

the raw hash from which this object was constructed.

Class Method Summary collapse

.mutable? ⇒ Boolean

By default,OAPIObjects (as a whole) are mutable, although some attributes may not be (see OAPI_PROPERTIES in the JSONObject docs).
.parse_oapi_properties ⇒ Object

create getters and setters for subclasses of APIObject based on their OAPI_PROPERTIES Hash.
.required_attributes ⇒ Object

An array of attribute names that are required when making new instances - they cannot be nil, but may be empty.
.validate_attr(attr_name, value) ⇒ Object

Used by auto-generated setters and .create to validate new values.

Constructor Details

#initialize(data) ⇒ `OAPIObject`

Make an instance. Data comes from the API

Parameters:

data (Hash) —

the data for constructing a new object.

# File 'lib/jamf/api/jamf_pro/base_classes/oapi_object.rb', line 347

def initialize(data)
  @init_data = data

  # creating a new one, not fetching from the API
  creating = data.delete :creating_from_create

  if creating
    self.class::OAPI_PROPERTIES.each_key do |attr_name|
      # we'll enforce required values when we save
      next unless data.key? attr_name

      # use our setters for each value so that they are validated, and
      # in the unsaved changes list
      send "#{attr_name}=", data[attr_name]
    end
    return

Class Method Details

.mutable? ⇒ `Boolean`

By default,OAPIObjects (as a whole) are mutable, although some attributes may not be (see OAPI_PROPERTIES in the JSONObject docs)

When an entire sublcass of OAPIObject is read-only/immutable, `extend Jamf::Immutable`, which will override this to return false. Doing so will prevent any setters from being created for the subclass and will cause Jamf::Resource.save to raise an error

Returns:

(Boolean)

end

.parse_oapi_properties ⇒ `Object`

create getters and setters for subclasses of APIObject based on their OAPI_PROPERTIES Hash.

This method can't be private, cuz we want to call it from a Zeitwerk callback when subclasses are loaded.

# File 'lib/jamf/api/jamf_pro/base_classes/oapi_object.rb', line 69

  got_primary = false

  self::OAPI_PROPERTIES.each do |attr_name, attr_def|
    Jamf.load_msg "Creating getters and setters for attribute '#{attr_name}' of #{self}"

    # see above comment
    # don't make one for :id, that one's hard-coded into CollectionResource
    # create_list_methods(attr_name, attr_def) if need_list_methods && attr_def[:identifier] && attr_name != :id

    # there can be only one (primary ident)
    if attr_def[:identifier] == :primary
      raise Jamf::UnsupportedError, 'Two identifiers marked as :primary' if got_primary

      got_primary = true
    end

    # create getter unless the attr is write only
    create_getters attr_name, attr_def unless attr_def[:writeonly]

    # Don't crete setters for readonly attrs, or immutable objects
    next if attr_def[:readonly] || !mutable?

    create_setters attr_name, attr_def
  end #  do |attr_name, attr_def|

  @oapi_properties_parsed = true
end

.required_attributes ⇒ `Object`

An array of attribute names that are required when making new instances - they cannot be nil, but may be empty.

end

.validate_attr(attr_name, value) ⇒ `Object`

Used by auto-generated setters and .create to validate new values.

returns a valid value or raises an exception

This method only validates single values. When called from multi-value setters, it is used for each value individually.

Parameters:

attr_name (Symbol) —

, a top-level key from OAPI_PROPERTIES for this class
value (Object) —

the value to validate for that attribute.

Returns:

(Object) —

The validated, possibly converted, value.

Raises:

(ArgumentError)

def self.validate_attr(attr_name, value)
  attr_def = self::OAPI_PROPERTIES[attr_name]

  # validate the value based on the OAPI definition.

  # if this is an identifier, it must be unique
