Constructor Details

#initialize({ Symbol = > Object }) ⇒ SuperStruct #initialize([ value1, value1, ... ]) ⇒ SuperStruct #initialize(value1, value1, ...) ⇒ SuperStruct

Overwrites the standard Struct initializer to add the ability to create an instance from a Hash of parameters.

Examples:

attributes = { :foo => 1, :bar => "baz" }
Struct.new(attributes)
# => #<Struct foo=1, bar="baz">

Overloads:

  • #initialize({ Symbol = > Object }) ⇒ SuperStruct

    Initializes the object with a key/value hash.

    Parameters:

    • values ({ Symbol => Object })
  • #initialize([ value1, value1, ... ]) ⇒ SuperStruct

    Initializes the object with given values.

    Parameters:

    • values (Array)
  • #initialize(value1, value1, ...) ⇒ SuperStruct

    Initializes the object with given values.

Yields:

  • self
