Overview

Convert input into hash

Input value can be anything implementing :to_hash method.

Example

class Piece
  include Aws::Templates::Utils::Parametrized

  parameter :param, :transform => as_hash
  parameter :param2,
    transform: as_hash {
      value name: :number,
        description: 'Number',
        constraint: not_nil,
        transform: as_integer
    }
end

i = Piece.new
i.param # => nil
i = Piece.new(:param => [[1,2]])
i.param # => {1=>2}
i = Piece.new(:param2 => [[1,'3']])
i.param # => {1=>3}
