org.apache.commons.configuration2.tree.InMemoryNodeModel
An interface used internally for handling concurrent updates. An implementation has to populate the passed in {@code ModelTransaction}. The transaction is then executed, and an atomic update of the model's {@code TreeData} is attempted. If this fails - because another updatecame across -, the whole operation has to be tried anew.
