Method Detail

sizeOfReservation

public abstract int sizeOfReservation(hudson.model.Computer computer,
                                      long timestamp)

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.

Parameters:

computer - Computer for which the reservation is computed.

timeOfNextChange

public abstract long timeOfNextChange(hudson.model.Computer computer,
                                      long timestamp)

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

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