add
Registers a task from its ID and implementation class.
Return
This Dag, for chaining.
Parameters
id
Task identifier, unique within this Dag.
definition
Class that implements Task. Must have a public no-arg constructor.
Throws
if a task with the same ID is already registered.
Registers a task with this Dag.
A TaskDef belongs to at most one DagDef; registering the same instance with a second Dag, or twice with the same one, fails. Task IDs must be unique within a Dag. Tasks named as upstreams by Deps.Flow.before or Deps.Flow.after must be registered with the same Dag by the time it is added to a Bundle.
Return
This Dag, for chaining.
Parameters
task
Task definition to register.
Throws
if the task already belongs to a Dag or a task with the same ID is already registered.
