Method Detail

backtrack

public void backtrack(EntityGraphTraversalState.TraversalResult previousContext)

Description copied from interface: EntityGraphTraversalState

Backtrack to previous entity graph status before last traversal. Mainly reset the current context entity graph node to the passed method parameter.

Specified by:

backtrack in interface EntityGraphTraversalState

Parameters:

previousContext - The previous entity graph context node; should not be null

traverse

public EntityGraphTraversalState.TraversalResult traverse(FetchParent fetchParent,
                                                          Fetchable fetchable,
                                                          boolean exploreKeySubgraph)

Description copied from interface: EntityGraphTraversalState

Traverses to the next part of the Jakarta Persistence entity graph relating to the given fetchable.

The AttributeNode corresponding to the given `fetchable` is resolved. Depending on `exploreKeySubgraph`, either AttributeNode.getSubGraphs() or AttributeNode.getKeySubGraphs() will be used

Specified by:
