Method Details

name

public String name()

Returns repository name

Returns:

repository name

type

public String type()

Returns repository type

Returns:

repository type

uuid

public String uuid()

Return the repository UUID, if set and known. The repository UUID is stored in the repository and typically populated here when the repository is registered or when we write to it. It may not be set if the repository is maintaining support for versions before SnapshotsService.UUIDS_IN_REPO_DATA_VERSION. It may not be known if the repository was registered with ?verify=false and has had no subsequent writes. Consumers may, if desired, try and fill in a missing value themselves by retrieving the RepositoryData and calling RepositoriesService.updateRepositoryUuidInMetadata(org.elasticsearch.cluster.service.ClusterService, java.lang.String, org.elasticsearch.repositories.RepositoryData, org.elasticsearch.action.ActionListener<java.lang.Void>).

Returns:

repository UUID, or RepositoryData.MISSING_UUID if the UUID is not set or not known.

settings

public Settings settings()

Returns repository settings

Returns:

repository settings

generation

public long generation()

Returns the safe repository generation. RepositoryData for this generation is assumed to exist in the repository. All operations on the repository must be based on the RepositoryData at this generation. See package level documentation for the blob store based repositories org.elasticsearch.repositories.blobstore for details on how this value is used during snapshots.

Returns:

safe repository generation

pendingGeneration

public long pendingGeneration()

Returns the pending repository generation. RepositoryData for this generation and all generations down to the safe generation generation may exist in the repository and should not be reused for writing new RepositoryData to the repository. See package level documentation for the blob store based repositories org.elasticsearch.repositories.blobstore for details on how this value is used during snapshots.

Returns:

highest pending repository generation

writeTo

public void writeTo(StreamOutput out)
             throws IOException

Writes repository metadata to stream output

Specified by:

writeTo in interface Writeable

Parameters:

out - stream output

Throws:

IOException

equalsIgnoreGenerations

public boolean equalsIgnoreGenerations(RepositoryMetadata other)

Checks if this instance is equal to the other instance in all fields other than generation and pendingGeneration.

Parameters:

other - other repository metadata

Returns:

true if both instances equal in all fields but the generation fields
