 org.cougaar.logistics.plugin.utils.TaskSchedulingPolicy
| TaskSchedulingPolicy | | public class TaskSchedulingPolicy (Code) | | A TaskSchedulingPolicy instance prioritizes tasks as to which
should be scheduled first.
There are n priority levels, each with an accompanying predicate/test
that tells whether a task is at that priority level.
If a task matches the predicate for more than one level, it is
assigned the highest level.
Note that the highest level corresponds to the lowest number (e.g.,
priority 0 is the highest priority and should be scheduled first).
A TaskSchedulingPolicy also can contain a sequence of time phases.
This specified how to break a task into different time periods without
actually expanding the task, hence allowing a plugin to handle
particular time periods before others.

| Constructor Summary | |
| public | TaskSchedulingPolicy(Predicate[] priorityTests)
Constructor when using just priorities and not phases
Parameters:
priorityTests - A set of tests that determines what prioritya given task is. | | public | TaskSchedulingPolicy(TimeSpan[] phases)
| | public | TaskSchedulingPolicy(Predicate[] priorityTests, PriorityPhaseMix[] ordering)
|
| PASSALL | | public static Predicate PASSALL(Code) | | Predicate that lets everything pass
|
| UNKNOWN_PRIORITY | | final public static int UNKNOWN_PRIORITY(Code) | | |
| TaskSchedulingPolicy | | public TaskSchedulingPolicy(Predicate[] priorityTests)(Code) | | Constructor when using just priorities and not phases
Parameters:
priorityTests - A set of tests that determines what prioritya given task is. If a task passes the test in the ithentry of the array but not previous test, then the task isof priority i. |
