All Implemented Interfaces:

Serializable

public class Disk
extends DiskInfo

A Google Compute Engine persistent disk. A disk can be used as primary storage for your virtual machine instances. Objects of this class are immutable. To get a Disk object with the most recent information use reload(com.google.cloud.compute.deprecated.Compute.DiskOption...). Disk adds a layer of service-related functionality over DiskInfo.

Method Detail

exists

public boolean exists()

Checks if this disk exists.

Returns:

true if this disk exists, false otherwise

Throws:

ComputeException - upon failure

reload

public Disk reload(Compute.DiskOption... options)

Fetches current disk's latest information. Returns null if the disk does not exist.

Parameters:

options - disk options

Returns:

a Disk object with latest information or null if not found

Throws:

ComputeException - upon failure

delete

public Operation delete(Compute.OperationOption... options)

Deletes this disk.

Returns:

a zone operation if the delete request was successfully sent, null if the disk was not found

Throws:

ComputeException - upon failure

createSnapshot

public Operation createSnapshot(String snapshot,
                                Compute.OperationOption... options)

Creates a snapshot for this disk given the snapshot's name.

Returns:

a zone operation for snapshot creation

Throws:

ComputeException - upon failure

createSnapshot

public Operation createSnapshot(String snapshot,
                                String description,
                                Compute.OperationOption... options)

Creates a snapshot for this disk given the snapshot's name and description.

Returns:

a zone operation for snapshot creation

Throws:

ComputeException - upon failure

createImage

public Operation createImage(String image,
                             Compute.OperationOption... options)

Creates an image for this disk given the image's name.

Returns:

a global operation if the image creation was successfully requested

Throws:

ComputeException - upon failure

createImage

public Operation createImage(String image,
                             String description,
