Method Detail

addOrderTo

public void addOrderTo(ExtendedOrder eo,

                       int curTime)
                throws java.lang.Exception

Adds the order to the taskplan after the last station before useable tasks. If the current taskplan contains the the load station [and the unload station] its [they're] reused if possible.

Parameters:

eo - The order to be added to the taskplan

plan - The taskplan to add the tasks for the order to

lastBeforePlan - The station to add the tasks for the order after

curTime -

Throws:

java.lang.Exception

java.lang.Exception - Thrown if there isn't a path to add the order

addOrderBehind

public void addOrderBehind(ExtendedOrder eo,
                           TaskPlanInterface plan,
                           int lastBeforePlan,
                           int curTime)
                    throws java.lang.Exception

Adds the order to the taskplan after the current tasks of the taskplan, at least after the last station before useable tasks.

Parameters:

eo - The feature to be added to the OrderBehindRoute attribute

plan - The feature to be added to the OrderBehindRoute attribute

lastBeforePlan - The feature to be added to the OrderBehindRoute attribute

curTime -

Throws:

java.lang.Exception

java.lang.Exception - Exception description not provided

getShortestBetween

                                     throws java.lang.Exception

Returns the shortest taskplan between start and destination without use of edge dontUse. Tasks will added to the returned taskplan with the given order id.

Parameters:

start - The start node of the returned taskplan

dest - The destination node of the returned taskplan

id - The order id that will be used to add tasks to the returned taskplan

not - The edge that don't will be contained in the returned taskplan.

Returns:

The shortest taskplan between start and destination, without use of the edge dontUse.

Throws:

java.lang.Exception - An Exception will be thrown if no path exists.
