NAME

       VM::EC2::BlockDevice::Mapping - Object describing an EC2 block device attached to an
       instance

SYNOPSIS

         use VM::EC2;

         $ec2        = VM::EC2->new(...);
         $instance   = $ec2->describe_instances(-instance_id=>'i-123456');
         my @devices   = $instance->blockDeviceMapping;
         for my $dev (@devices) {
           $dev       = $dev->deviceName;
           $volume_id = $dev->volumeId;
           $status    = $dev->status;
           $atime     = $dev->attachmentTime;
           $delete    = $dev->deleteOnTermination;
           $volume    = $dev->volume;
         }

DESCRIPTION

       This object represents an Amazon block device associated with an instance; it is returned
       by Instance->blockDeviceMapping().

       Please see VM::EC2::Generic for methods shared by all VM::EC2 objects.

METHODS

       These object methods are supported:

        deviceName  -- Name of the device, such as /dev/sda1.
        instance    -- Instance object associated with this volume.
        ebs         -- A VM::EC2::BlockDevice::Mapping::EBS object
                       describing the characteristics of the attached
                       EBS volume

       For your convenience, a number of the ebs() object's methods are passed through:

        volumeId         -- ID of the volume.
        status           -- One of "attaching", "attached", "detaching", "detached"
        attachTime       -- Time this volume was attached
        deleteOnTermination -- Whether the volume will be deleted when its attached
                          instance is deleted. Note that this will return perl true/false
                          vales, rather than the strings "true" "false".

       The deleteOnTermination() method can be used to retrieve or modify this flag:

        # get current deleteOnTermination flag
        my $current_flag = $dev->deleteOnTermination;

        # if flag is true, then set it to false
        if ($current_flag) { $dev->deleteOnTermination(0) }

       In addition, the following convenience function is provided:

   $volume = $dev->volume
       This returns a VM::EC2::Volume object from which more information about the volume, such
       as its size, can be derived.

STRING OVERLOADING

       When used in a string context, this object will be interpolated as the deviceName.
