Enumeration IlcActivityIteratorFilter

Given an activity act on a schedule with a schedule precedence graph, several useful sets of activities can be defined with respect to act (set of successors of act, set of predecessors of act, etc.).

The enumeration IlcActivityIteratorFilter can be used to create an activity iterator IlcActivityIterator that allows traversing such sets of activities. Each element of the enumeration specifies a particular set to traverse.

IlcPredecessors specifies that the iterator traverse the set of activities that are predecessors of a given activity.

IlcSuccessors specifies that the iterator traverse the set of activities that are successors of a given activity.

IlcDirectPredecessors specifies that the iterator traverse the set of activities that are direct predecessors of a given activity.

IlcDirectSuccessors specifies that the iterator traverse the set of activities that are direct successors of a given activity.

IlcUnranked specifies that the iterator traverse the set of activities that are unranked with respect to a given activity.
