Method Detail

taskInfo

public TaskInfo taskInfo(DiscoveryNode node,
                         boolean detailed)

Build a version of the task status you can throw over the wire and back to the user.

Parameters:

node - the node this task is running on

detailed - should the information include detailed, potentially slow to generate data?

getId

public long getId()

Returns task id

getType

public String getType()

Returns task channel type (netty, transport, direct)

getAction

public String getAction()

Returns task action

getDescription

public String getDescription()

Generates task description

getStartTime

public long getStartTime()

Returns the task start time

getParentTaskId

public TaskId getParentTaskId()

Returns id of the parent task or NO_PARENT_ID if the task doesn't have any parent tasks

getStatus

public Task.Status getStatus()

Build a status for this task or null if this task doesn't have status. Since most tasks don't have status this defaults to returning null. While this can never perform IO it might be a costly operation, requiring collating lists of results, etc. So only use it if you need the value.
