METHODS ^

These object methods are supported:

 spotInstanceRequestId       -- ID of this spot instance request

                instance launched under this request,
                in USD.

                and terminated together.

 availabilityZoneGroup -- Availability zone group of the instances
                run under this request. Instances in the same
                availability zone group will always be launched
                into the same availability zone.

 launchSpecification -- Additional information for launching
                instances, represented as a VM::EC2::Spot::LaunchSpecificaton
                object.

 instanceId  -- The instance ID, if an instance has been launched as a 
                result of this request.

                created.

                instance request.

Convenience Methods ^

This class supports the standard tagging interface. In addition it provides the following convenience method:

$instance = $request->instance

If an instance was launched as a result of this request, the instance() method will return the corresponding VM::EC2::Instance object.

$state = $request->current_status

Refreshes the request information and returns its status as a VM::EC2::Spot::Status. This will string interpolate as the status code, such as "fulfilled". You may also call its object methods to get the time of the last update and full message.

$state = $request->current_state

Refreshes the request information and returns its state, such as "open".

$request->refresh

Refreshes the request information.
