getWriteableName

public String getWriteableName()

Description copied from interface: VersionedNamedWriteable

Returns the name of the writeable object

Specified by:

getWriteableName in interface NamedWriteable

Specified by:

getWriteableName in interface VersionedNamedWriteable

getMinimalSupportedVersion

public Version getMinimalSupportedVersion()

Description copied from interface: VersionedNamedWriteable

The minimal version of the recipient this object can be sent to

Specified by:

getMinimalSupportedVersion in interface VersionedNamedWriteable

readDiffFrom

public static NamedDiff<ClusterState.Custom> readDiffFrom(StreamInput in)
                                                   throws IOException

Throws:

writeTo

public void writeTo(StreamOutput out)
             throws IOException

Description copied from interface: Writeable

Write this into the StreamOutput.

Specified by:

toXContent

public org.elasticsearch.xcontent.XContentBuilder toXContent(org.elasticsearch.xcontent.XContentBuilder builder,
 org.elasticsearch.xcontent.ToXContent.Params params)
                                                      throws IOException

Description copied from interface: ClusterState.Custom

Serialize this ClusterState.Custom for diagnostic purposes, exposed by the

GET _cluster/state

API etc. The XContent representation does not need to be 100% faithful since we never reconstruct a cluster state from its XContent representation, but the more faithful it is the more useful it is for diagnostics.

Specified by:

toXContent in interface ClusterState.Custom

Specified by:

toXContent in interface org.elasticsearch.xcontent.ToXContent

Throws:

IOException

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()

Overrides:

toString in class Object

startedEntry

public static SnapshotsInProgress.Entry startedEntry(Snapshot snapshot,
 boolean includeGlobalState,

Creates the initial SnapshotsInProgress.Entry when starting a snapshot, if no shard-level snapshot work is to be done the resulting entry will be in state SnapshotsInProgress.State.SUCCESS right away otherwise it will be in state SnapshotsInProgress.State.STARTED.

startClone

version - repository metadata version to write

Returns:

snapshot clone entry

completed

public static boolean completed(Collection<SnapshotsInProgress.ShardSnapshotStatus> shards)

Checks if all shards in the list have completed

Parameters:

shards - list of shard statuses

Returns:

true if all shards have completed (either successfully or failed), false otherwise
