Nested and Inner Type Summary

Modifier and Type	Class and Description
public static class	EntityGraphTraversalState.FetchStrategy
public static class	EntityGraphTraversalState.TraversalResult Details of a particular traversal within the entity graph

Method Summary

Modifier and Type	Method and Description
public void	backtrack(EntityGraphTraversalState.TraversalResult The previous entity graph context node; should not be null previousContext) Backtrack to previous entity graph status before last traversal.
public EntityGraphTraversalState.TraversalResult	traverse(FetchParent parent, Fetchable fetchable, boolean exploreKeySubgraph) Traverses to the next part of the Jakarta Persistence entity graph relating to the given fetchable.

Method Detail

backtrack	back to summary
public void backtrack(EntityGraphTraversalState.TraversalResult previousContext) Backtrack to previous entity graph status before last traversal. Mainly reset the current context entity graph node to the passed method parameter. Parameters previousContext:EntityGraphTraversalState.TraversalResult The previous entity graph context node; should not be null See Also `traverse(FetchParent, Fetchable, boolean)`

traverse	back to summary
public EntityGraphTraversalState.TraversalResult traverse(FetchParent parent, Fetchable fetchable, boolean exploreKeySubgraph) 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
