CollapsibleCriteria (OpenNMS 28.0.2 API)

All Known Subinterfaces:

SearchCriteria

All Known Implementing Classes:

AlarmHopCriteria, CategoryHopCriteria, IpLikeHopCriteria
```
public interface CollapsibleCriteria
```
This interface indicates that a criteria can be used to "collapse" elements of the graph. When collapsed, all of the elements of the graph will be replaced with a single vertex that represents all of the members. Edges that point to any member will be attached to the single vertex.
