GuzzleHttp\Promise\Promise
each (
callable
$handleResult
)
Runs a paginator asynchronously and uses a callback to handle results.
The callback should have the signature: function (Aws\Result $result). A non-null return value from the callback will be yielded by the promise. This means that you can return promises from the callback that will need to be resolved before continuing iteration over the remaining items, essentially merging in other promises to the iteration. The last non-null value returned by the callback will be the result that fulfills the promise to any downstream promises.
Parameters
| callable | $handleResult | Callback for handling each page of results. The callback accepts the result that was yielded as a single argument. If the callback returns a promise, the promise will be merged into the coroutine. |
Returns
GuzzleHttp\Promise\Promise |
Iterator search ( string $expression )
Returns an iterator that iterates over the values of applying a JMESPath search to each result yielded by the iterator as a flat sequence.
Parameters
| string | $expression | JMESPath expression to apply to each result. |
Returns
| Iterator |
