Class DeepCopyMapper<T>

java.lang.Object

org.goplanit.utils.misc.DeepCopyMapper<T>

Type Parameters:

T - type of entity

All Implemented Interfaces:

BiConsumer<T,T>

Direct Known Subclasses:

GraphEntityDeepCopyMapper, ManagedIdDeepCopyMapper

public class DeepCopyMapper<T>
extends Object
implements BiConsumer<T,T>

A bi-consumer that tracks the mapping of an original and deep copy that was created such mappings are required when dependencies within the copied instances exist that require updating after-the-fact, e.g., a deep copy of nodes and links where link shave references to nodes. After deep copying both containers, the references to the nodes need updating on the links. this is the mapping that is required to be able to know how to do that
