@deprecated Use [Aws::RDS::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
