Class ObjectGraphTraverser

java.lang.Object

cz.cvut.kbss.jsonld.serialization.traversal.ObjectGraphTraverser

public class ObjectGraphTraverser
extends Object

Traverses the provided object graph, visiting each instance and its fields, notifying visitors of these encounters.

Each object is visited only once, so circular references are not a problem.

The traversal algorithm is depth-first in nature.
