Method Detail

sizeOfReservation

public int sizeOfReservation(long timestamp)

Description copied from class: SlaveSquatter

Returns the number of executors that should be reserved at the specified time.

The timestamp is the same format as Date.getTime(). The precision is 1 minute, and thus the caller should set the second and millisecond portion to 00.000.

Specified by:

sizeOfReservation in class SlaveSquatter

timeOfNextChange

public long timeOfNextChange(long timestamp)

Description copied from class: SlaveSquatter

Given the timestamp, return the nearest future timestamp (including itself --- the ceil semantics) when the size of the reservation changes.

Hudson uses this information to figure out the scheduling that takes the future capacity change into account.
