Examples of AllocatedResource

eu.stratosphere.nephele.instance.AllocatedResource
An allocated resource object unambiguously defines the hardware resources which have been assigned to an {@link eu.stratosphere.nephele.executiongraph.ExecutionVertex} forexecuting a task. The allocated resource is comprised of an {@link eu.stratosphere.nephele.instance.AbstractInstance}which identifies the node the task is scheduled to run on as well as an {@link eu.stratosphere.nephele.instance.AllocationID} which determines the resources the task is scheduled toallocate within the node.
The class is thread-safe.
