Package org.elasticsearch.tasks

Class TaskInfo

java.lang.Object

org.elasticsearch.tasks.TaskInfo

All Implemented Interfaces:

Writeable, ToXContent, ToXContentFragment

public final class TaskInfo
extends Object
implements Writeable, ToXContentFragment

Information about a currently running task.

Tasks are used for communication with transport actions. As a result, they can contain callback references as well as mutable state. That makes it impractical to send tasks over transport channels and use in APIs. Instead, immutable and writeable TaskInfo objects are used to represent snapshot information about currently running tasks.
