Method Detail

initialize

void initialize(ilog.views.gantt.IlvGanttModel model,
              ilog.views.gantt.IlvActivity[] selectedActivities)
                throws java.lang.Exception

Called to let the extension code initialize anything needed for the CPM extension logic. The selectedActivities will be null, if the CPM is applied to the entire schedule.

Parameters:

model - GanttModel

selectedActivities - selected activities, will be null, if CPM is applied on all

Throws:

java.lang.Exception

computeEarlyStartAndFinish

SKDCPMAdjustedActivityData computeEarlyStartAndFinish(ilog.views.gantt.IlvGanttModel model,
                                                    ilog.views.gantt.IlvActivity activity,
                                                    java.util.Date parentEarlyStart,
                                                    java.util.Date activityEarlyStart,
                                                    java.util.Date activityEarlyFinish)
                                                      throws java.lang.Exception

Compute the early start of the activity based on an already computed early start and early finish values. Note that if there are multiple extensions, then the earliest dates of all extension's are used as the earliest start date for the activity. Note that the extension should try to calculate the early start date following the early start already computed by the basic CPM. The early start date computed must not be before the already computed early start (i.e it should always be >= activityEarlyStart).

Parameters:

model - GanttModel

activity - activity on which the early start and finish need to be computed.

parentEarlyStart - parent node's early start

activityEarlyStart - activity early start as determined by the basic CPM logic

activityEarlyFinish - activity early finish as determined by the basic CPM logic

Returns:

Throws:

java.lang.Exception

isEarlyStartAndFinishAcceptable

boolean isEarlyStartAndFinishAcceptable(ilog.views.gantt.IlvGanttModel model,
                                      ilog.views.gantt.IlvActivity activity,
                                      java.util.Date parentEarlyStart,
                                      java.util.Date activityEarlyStart,
                                      java.util.Date activityEarlyFinish)
                                        throws java.lang.Exception

Returns true, if the activity early start and finish are acceptable to this extension or not.

Parameters:

model - GanttModel

activity - activity on which the early start and finish need to be computed.

parentEarlyStart - parent node's early start

activityEarlyStart - activity early start as determined by the basic CPM logic

activityEarlyFinish - activity early finish as determined by the basic CPM logic

Returns:

Throws:

java.lang.Exception

computeLateStartAndFinish

                                                     throws java.lang.Exception

Compute the late start of the activity based on an already computed late start and late finish values. Note that if there are multiple extensions, then the latest dates of all extension's are used as the latest start date for the activity. Note that the extension should try to calculate the late start date following the late start already computed by the basic CPM. The late start date computed must not be before the already computed late start (i.e it should always be >= activityLateStart).

Parameters:

model - GanttModel

activity - activity on which the late start and finish need to be computed.

parentLatestFinish - parent node's late start

activityLateStart - activity late start as determined by the basic CPM logic

activityLatefinish - activity late finish as determined by the basic CPM logic

Returns:

Throws:

java.lang.Exception

                                       throws java.lang.Exception

Returns true, if the activity late start and finish are acceptable to this extension or not.

Parameters:

model - GanttModel

activity - activity on which the late start and finish need to be computed.

parentLatestFinish - parent node's late start

activityLateStart - activity late start as determined by the basic CPM logic

activityLatefinish - activity late finish as determined by the basic CPM logic

Returns:

Throws:

java.lang.Exception

void release(ilog.views.gantt.IlvGanttModel model,
           ilog.views.gantt.IlvActivity[] selectedActivities,
           boolean success)

Called to indicate to the extension that the CPM process has completed and indicates the status
