Instance Method Details

#sl_warden(rescue_proc = nil, retry_interval = 0, &block) ⇒ Object

Handles gracefully SoftLayer API calls.

The block code is executed, catching both common connection errors and API exceptions.

Optionally, in the not-so-uncommon case when the object (e.g. the SoftLayer instance) is not found, executes a proc and/or retry the API call after some seconds.

A future version of the method will add a retry timeout.
