Instance Public methods
==(other_aggregation)

Returns trueif selfand other_aggregationhave the same nameattribute, active_recordattribute, and other_aggregation has an options hash assigned to it.

# File activerecord/lib/active_record/reflection.rb, line 117
def ==(other_aggregation)
  other_aggregation.kind_of?(self.class) && name == other_aggregation.name && other_aggregation.options && active_record == other_aggregation.active_record
end
belongs_to?()

Returns trueif selfis a belongs_to reflection.

# File activerecord/lib/active_record/reflection.rb, line 126
def belongs_to?
  macro == :belongs_to
end
class_name()

Returns the class name for the macro. For example, composed_of :balance, :class_name => 'Money'returns 'Money'and has_many :clientsreturns 'Client'.

# File activerecord/lib/active_record/reflection.rb, line 111
def class_name
  @class_name ||= options[:class_name] || derive_class_name
end
klass()

Returns the class for the macro. For example, composed_of :balance, :class_name => 'Money'returns the Money class and has_many :clientsreturns the Client class.

# File activerecord/lib/active_record/reflection.rb, line 105
def klass
  @klass ||= class_name.constantize
end
macro()

Returns the macro type. For example, composed_of :balance, :class_name => 'Money'will return :composed_ofor for has_many :clientswill return :has_many.

# File activerecord/lib/active_record/reflection.rb, line 93
def macro
  @macro
end
name()

Returns the name of the macro. For example, composed_of :balance, :class_name => 'Money'will return :balance or for has_many :clientsit will return :clients.

# File activerecord/lib/active_record/reflection.rb, line 87
def name
  @name
end
options()

Returns the hash of options used for the macro. For example, it would return { :class_name => "Money" }for composed_of :balance, :class_name => 'Money'or +{}+ for has_many :clients.
