@param [Hash] options ({}) @option options [required, Types::NotificationConfiguration] :notification_configuration

A container for specifying the notification configuration of the
bucket. If this element is empty, notifications are turned off for the
bucket.

The account ID of the expected bucket owner. If the bucket is owned by
a different account, the request will fail with an HTTP `403 (Access
Denied)` error.

wait_until(options = {}, &block) click to toggle source

@deprecated Use [Aws::S3::Client] wait_until instead

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

@note The waiting operation is performed on a copy. The original resource

remains unchanged.

## 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

@yieldparam [Resource] resource to be used in the waiting condition.

@raise [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.

@raise [Aws::Waiters::Errors::UnexpectedError] Raised when an error is

encountered while polling for a resource that is not expected.

@raise [NotImplementedError] Raised when the resource does not
