Method Detail

getFingerprint

public String getFingerprint()

Specifies a fingerprint for this request, which is essentially a hash of the metadata's contents and used for optimistic locking. The fingerprint is initially generated by Compute Engine and changes after every request to modify or update metadata. You must always provide an up-to-date fingerprint hash in order to update or change metadata, otherwise the request will fail with error 412 conditionNotMet. To see the latest fingerprint, make a get() request to retrieve the resource.

Returns:

value or null for none

See Also:

decodeFingerprint()

decodeFingerprint

public byte[] decodeFingerprint()

Specifies a fingerprint for this request, which is essentially a hash of the metadata's contents and used for optimistic locking. The fingerprint is initially generated by Compute Engine and changes after every request to modify or update metadata. You must always provide an up-to-date fingerprint hash in order to update or change metadata, otherwise the request will fail with error 412 conditionNotMet. To see the latest fingerprint, make a get() request to retrieve the resource.

Returns:

Base64 decoded value or null for none

Since:

1.14

See Also:

getFingerprint()

setFingerprint

public Metadata setFingerprint(String fingerprint)

Specifies a fingerprint for this request, which is essentially a hash of the metadata's contents and used for optimistic locking. The fingerprint is initially generated by Compute Engine and changes after every request to modify or update metadata. You must always provide an up-to-date fingerprint hash in order to update or change metadata, otherwise the request will fail with error 412 conditionNotMet. To see the latest fingerprint, make a get() request to retrieve the resource.

Parameters:

fingerprint - fingerprint or null for none

See Also:

#encodeFingerprint()

encodeFingerprint

public Metadata encodeFingerprint(byte[] fingerprint)

Specifies a fingerprint for this request, which is essentially a hash of the metadata's contents and used for optimistic locking. The fingerprint is initially generated by Compute Engine and changes after every request to modify or update metadata. You must always provide an up-to-date fingerprint hash in order to update or change metadata, otherwise the request will fail with error 412 conditionNotMet. To see the latest fingerprint, make a get() request to retrieve the resource.

Since:

1.14

See Also:

The value is encoded Base64 or {@code null} for none.

getItems

public List<Metadata.Items> getItems()

Array of key/value pairs. The total size of all keys and values must be less than 512 KB.

Returns:

value or null for none

setItems

public Metadata setItems(List<Metadata.Items> items)

Array of key/value pairs. The total size of all keys and values must be less than 512 KB.

Parameters:

items - items or null for none

getKind

public String getKind()

[Output Only] Type of the resource. Always compute#metadata for metadata.

Returns:

value or null for none

setKind

public Metadata setKind(String kind)

[Output Only] Type of the resource. Always compute#metadata for metadata.

Parameters:

kind - kind or null for none

set

public Metadata set(String fieldName,
                    Object value)

Overrides:

set in class GenericJson

clone

public Metadata clone()

Overrides:

clone in class GenericJson
