Class TaskInfo

java.lang.Object

org.elasticsearch.action.admin.cluster.node.tasks.list.TaskInfo

All Implemented Interfaces:

StreamableReader<TaskInfo>, Writeable<TaskInfo>, ToXContent

public class TaskInfo
extends Object
implements Writeable<TaskInfo>, ToXContent

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 streamable TaskInfo objects are used to represent snapshot information about currently running tasks.
