Constructor Details

#initialize(opts = {}) {|_self| ... } ⇒ Statement

Constructs a new statement.

Parameters:

  • opts (Hash) (defaults to: {}) —

    a customizable set of options

Options Hash (opts):

  • :sid (String) —

    The statement ID. This is optional; if omitted, a UUID will be generated for the statement.

  • :effect (String) —

    The statement effect, which must be either “Allow” or “Deny”. @see Policy#allow @see Policy#deny

  • :principals (String or array of strings) —

    The account(s) affected by the statement. These should be AWS account IDs.

  • :actions (Object) —

    The action or actions affected by the statement. These can be symbols or strings. If they are strings, you can use wildcard character “*” to match zero or more characters in the action name. Symbols are expected to match methods of S3::Client.

  • :excluded_actions (Object) —

    Action or actions which are explicitly not affected by this statement. As with :actions, these may be symbols or strings.

  • :resources (String or array of strings) —

    The resource(s) affected by the statement. These can be expressed as ARNs (e.g. arn:aws:s3:::mybucket/mykey) or you may omit the arn:aws:s3::: prefix and just give the path as bucket_name/key. You may use the wildcard character “*” to match zero or more characters in the resource name.

  • :conditions (ConditionBlock or Hash) —

    Additional conditions that narrow the effect of the statement. It’s typically more convenient to use the ConditionBuilder instance returned from Policy#allow or Policy#deny to add conditions to a statement.

Yields:

  • (_self)

Yield Parameters:

  • S3::Client
