Class Resource

java.lang.Object

hudson.model.Resource

public final class Resource
extends Object

Represents things that Queue.Executable uses while running.

This is used in Queue to support basic mutual exclusion/locks. If two Queue.Tasks require the same Resource, they will not be run at the same time.

Resources are compared by using their names, and need not have the "same object" semantics.
