org.elasticsearch.script.Metadata

org.elasticsearch.script.ReindexMetadata

public class ReindexMetadata
extends Metadata

Metadata for the ReindexScript context. _index, _id, _version, _routing are all read-write. _id, _version and _routing are also nullable. _now is millis since epoch and read-only op is read-write one of 'index', 'noop', 'delete' If _version is set to null in the ctx map, that is interpreted as using internal versioning. The setVersionToInternal(Metadata) and isVersionInternal(Metadata) augmentations are provided for users of this class. These augmentations allow the class to appear as Metadata but handle the internal versioning scheme without scripts accessing the ctx map.

 long timestamp)

Method Details

metadataMap

protected static Map<String,Object> metadataMap(String index,
 String id,
 Long version,
 String routing,
 String op,
 long timestamp)

Create the backing metadata map with the standard contents assuming default validators.

getVersion

public long getVersion()

Get version, if it's null, return sentinel value Long.MIN_VALUE

Overrides:

getVersion in class Metadata

isVersionInternal

public boolean isVersionInternal()

isVersionInternal

public static boolean isVersionInternal(Metadata receiver)

Augmentation to allow ReindexScripts to check if the version is set to "internal"

setVersionToInternal

public static void setVersionToInternal(Metadata receiver)

Augmentation to allow ReindexScripts to set the version to "internal". This is necessary because Metadata.setVersion(long) takes a primitive long.

versionChanged

public boolean versionChanged()

indexChanged

public boolean indexChanged()

idChanged

public boolean idChanged()

routingChanged

public boolean routingChanged()
