#==(other) ⇒ `Boolean`

Parameters:

other (Object)

Returns:

(Boolean)

222	# File 'lib/method_ruby/internal/type/base_model.rb', line 222 def ==(other) = self.class == other.class && @data == other.to_h

#[](key) ⇒ `Object`^?

Returns the raw value associated with the given key, if found. Otherwise, nil is returned.

It is valid to lookup keys that are not in the API spec, for example to access undocumented features. This method does not parse response data into higher-level types. Lookup by anything other than a Symbol is an ArgumentError.

Parameters:

key (Symbol)

Returns:

(Object, nil)

# File 'lib/method_ruby/internal/type/base_model.rb', line 404

def [](key)
  unless key.instance_of?(Symbol)
    raise ArgumentError.new("Expected symbol key for lookup, got #{key.inspect}")
  end

  @data[key]
end

#deconstruct_keys(keys) ⇒ `Hash{Symbol=>Object}`

Examples:

# `address` is a `MethodRuby::Address`
address => {
  city: city,
  line1: line1,
  line2: line2
}

Parameters:

keys (Array<Symbol>, nil)

Returns:

(Hash{Symbol=>Object})

# File 'lib/method_ruby/internal/type/base_model.rb', line 447

def deconstruct_keys(keys)
  (keys || self.class.known_fields.keys)
    .filter_map do |k|
      unless self.class.known_fields.key?(k)
        next
      end

      [k, public_send(k)]
    end
    .to_h
end

#deep_to_h ⇒ `Hash{Symbol=>Object}`

In addition to the behaviour of ‘#to_h`, this method will recursively call `#to_h` on nested models.

Returns:

(Hash{Symbol=>Object})

434	# File 'lib/method_ruby/internal/type/base_model.rb', line 434 def deep_to_h = self.class.recursively_to_h(@data, convert: false)

#hash ⇒ `Integer`

Returns:

(Integer)

227	# File 'lib/method_ruby/internal/type/base_model.rb', line 227 def hash = [self.class, @data].hash

#inspect ⇒ `String`

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Returns:

(String)

# File 'lib/method_ruby/internal/type/base_model.rb', line 520

def inspect
  converted = self.class.recursively_to_h(self, convert: true)
  "#<#{self.class}:0x#{object_id.to_s(16)} #{converted}>"
end

#to_h ⇒ `Hash{Symbol=>Object}` Also known as: to_hash

Returns a Hash of the data underlying this object. O(1)

Keys are Symbols and values are the raw values from the response. The return value indicates which values were ever set on the object. i.e. there will be a key in this hash if they ever were, even if the set value was nil.

This method is not recursive. The returned value is shared by the object, so it should not be mutated.

Returns:

(Hash{Symbol=>Object})

424	# File 'lib/method_ruby/internal/type/base_model.rb', line 424 def to_h = @data

#to_json(*a) ⇒ `String`

Parameters:

a (Object)

Returns:

(String)

464	# File 'lib/method_ruby/internal/type/base_model.rb', line 464 def to_json(a) = MethodRuby::Internal::Type::Converter.dump(self.class, self).to_json(a)

#to_s ⇒ `String`

Returns:

(String)

515	# File 'lib/method_ruby/internal/type/base_model.rb', line 515 def to_s = deep_to_h.to_s

#to_yaml(*a) ⇒ `String`

Parameters:

a (Object)

Returns:

(String)

471	# File 'lib/method_ruby/internal/type/base_model.rb', line 471 def to_yaml(a) = MethodRuby::Internal::Type::Converter.dump(self.class, self).to_yaml(a)
