Method Detail

runAfter

public boolean runAfter(List tasks,
               int size)

Returns true if the current instance of this task must be run after at least one task in task manager queue. The criteria for determining what value to return is as follows: If there is at least one task in the given task list that is associated with the same serviceID as this task, and that task has a sequence number less than the sequence number of this task, then run this task *after* the task in the list (return true); otherwise run this task now (return false).

Specified by:

runAfter in interface TaskManager.Task

Overrides:

runAfter in class ServiceDiscoveryManager.CacheTask

Parameters:

tasks - the tasks to consider.

size - elements with index less than size are considered.

getServiceID

public ServiceID getServiceID()

Returns the ServiceID associated with this task.
