true when the associated task was scheduled on a specific member in the cluster

toUrn

public abstract String toUrn()

Useful for persisting and/or communicating this info. A ScheduledTaskHandler can be constructed again from the Urn String using of(String)

Returns:

URN representing the handler in a String format

of

public static ScheduledTaskHandler of(String urn)
