Overview

Aggregate constraint

It is used to perform checks against a list of constraints-functors or lambdas.

Example

class Piece
  include Aws::Templates::Utils::Parametrized
  parameter :param1,
    :constraint => all_of(
      not_nil,
      satisfies("Should be moderate") { |v| v < 100 }
    )
end

i = Piece.new(:param1 => nil)
i.param1 # raise ParameterValueInvalid
i = Piece.new(:param1 => 200)
i.param1 # raise ParameterValueInvalid with description
i = Piece.new(:param1 => 50)
i.param1 # => 50
