Method Summary

Methods

Modifier and Type	Method and Description
void	run()
boolean	runAfter(List tasks, int size) This method returns true if the current instance of this class must be run after at least one task in the input task list with an index less than the size parameter (size may be less than tasks.size()).
private void	setRegInfoGroups(FiddlerImpl.RegistrationInfo regInfo, String[] groups) Replaces the registration's managed set of groups with the new groups (even if the new set of groups is empty -- this just means group discovery will be "turned off" for this registration).

               int size)

This method returns true if the current instance of this class must be run after at least one task in the input task list with an index less than the size parameter (size may be less than tasks.size()).

Note that using List.get will be more efficient than List.iterator.

tasks - the tasks to consider. A read-only List, with all elements being an instanceof Task.

size - elements with index less than size should be considered
