Class ContainmentGraphCollector

java.lang.Object
  org.plasma.sdo.core.ContainmentGraphCollector

All Implemented Interfaces:

PlasmaDataGraphVisitor

public class ContainmentGraphCollector
extends Object
implements PlasmaDataGraphVisitor

Visits a data graph from a given source/root, collecting the source and any contained nodes from the source which are part of the contiguous containment hierarchy. Clients must call accept() passing this visitor to trigger the traversal from a given source data object.
