    Specifies the algorithm to use to when decrypting the object (for example, AES256).

  • :sse_customer_key (String) —

    Specifies the customer-provided encryption key for Amazon S3 used to encrypt the data. This value is used to decrypt the object when recovering it and must match the one used when storing the data. The key must be appropriate for use with the algorithm specified in the ‘x-amz-server-side-encryption-customer-algorithm` header.

  • :sse_customer_key_md5 (String) —

    Specifies the 128-bit MD5 digest of the encryption key according to RFC 1321. Amazon S3 uses this header for a message integrity check to ensure that the encryption key was transmitted without error.

Parameters:

    ({})

Options Hash (options):

  • :if_match (String) —

    Return the object only if its entity tag (ETag) is the same as the one specified; otherwise, return a 412 (precondition failed) error.

  • :if_modified_since (Time, DateTime, Date, Integer, String) —

  • :if_none_match (String) —

    Return the object only if its entity tag (ETag) is different from the one specified; otherwise, return a 304 (not modified) error.

  • :if_unmodified_since (Time, DateTime, Date, Integer, String) —

    Return the object only if it has not been modified since the specified time; otherwise, return a 412 (precondition failed) error.

  • :range (String) —

    Because ‘HeadObject` returns only the metadata for an object, this parameter has no effect.

  • :sse_customer_algorithm (String) —

    Specifies the algorithm to use to when encrypting the object (for example, AES256).

  • :sse_customer_key (String) —

    Specifies the customer-provided encryption key for Amazon S3 to use in encrypting data. This value is used to store the object and then it is discarded; Amazon S3 does not store the encryption key. The key must be appropriate for use with the algorithm specified in the ‘x-amz-server-side-encryption-customer-algorithm` header.

  • :sse_customer_key_md5 (String) —

    Specifies the 128-bit MD5 digest of the encryption key according to RFC 1321. Amazon S3 uses this header for a message integrity check to ensure that the encryption key was transmitted without error.

  • :request_payer (String) —

    Confirms that the requester knows that they will be charged for the request. Bucket owners need not specify this parameter in their requests.

    [1]: docs.aws.amazon.com/AmazonS3/latest/dev/ObjectsinRequesterPaysBuckets.html

  • :part_number (Integer) —

    Part number of the object being read. This is a positive integer between 1 and 10,000. Effectively performs a ‘ranged’ HEAD request for the part specified. Useful querying about the size of the part and the number of parts in this object.

  • :expected_bucket_owner (String) —

    The account ID of the expected bucket owner. If the bucket is owned by a different account, the request fails with the HTTP status code ‘403 Forbidden` (access denied).

  • :checksum_mode (String) —

    To retrieve the checksum, this parameter must be enabled.

    In addition, if you enable ‘ChecksumMode` and the object is encrypted with Amazon Web Services Key Management Service (Amazon Web Services KMS), you must have permission to use the `kms:Decrypt` action for the request to succeed.

#wait_until(options = {}) {|resource| ... } ⇒ Resource

Deprecated.

Use [Aws::S3::Client] #wait_until instead

Note:

The waiting operation is performed on a copy. The original resource remains unchanged.

Waiter polls an API operation until a resource enters a desired state.

## Basic Usage

Waiter will polls until it is successful, it fails by entering a terminal state, or until a maximum number of attempts are made.

# polls in a loop until condition is true
resource.wait_until(options) {|resource| condition}

## Example

instance.wait_until(max_attempts:10, delay:5) do |instance|
  instance.state.name == 'running'
end

## Configuration

You can configure the maximum number of polling attempts, and the delay (in seconds) between each polling attempt. The waiting condition is set by passing a block to #wait_until:

# poll for ~25 seconds
resource.wait_until(max_attempts:5,delay:5) {|resource|...}

## Callbacks

You can be notified before each polling attempt and before each delay. If you throw ‘:success` or `:failure` from these callbacks, it will terminate the waiter.

started_at = Time.now
# poll for 1 hour, instead of a number of attempts
proc = Proc.new do |attempts, response|
  throw :failure if Time.now - started_at > 3600
end

  # disable max attempts
instance.wait_until(before_wait:proc, max_attempts:nil) {...}

## Handling Errors

When a waiter is successful, it returns the Resource. When a waiter fails, it raises an error.

begin
  resource.wait_until(...)
rescue Aws::Waiters::Errors::WaiterFailed
  # resource did not enter the desired state in time
end

attempts attempt in seconds invoked before each attempt invoked before each wait

Parameters:

  • options (Hash) (defaults to: {}) —

    a customizable set of options

Options Hash (options):

  • :max_attempts (Integer) — default: 10 —

    Maximum number of

  • :delay (Integer) — default: 10 —

    Delay between each

  • :before_attempt (Proc) — default: nil —

    Callback

  • :before_wait (Proc) — default: nil —

    Callback

Yield Parameters:

  • resource (Resource) —

    to be used in the waiting condition.

Returns:

  • (Resource) —

    if the waiter was successful

Raises:

  • (Aws::Waiters::Errors::FailureStateError) —

    Raised when the waiter terminates because the waiter has entered a state that it will not transition out of, preventing success.

    yet successful.

  • (Aws::Waiters::Errors::UnexpectedError) —

    Raised when an error is encountered while polling for a resource that is not expected.

  • (NotImplementedError) —

    Raised when the resource does not
