public interface TraversalContext extends TraversalMetadata
TraversalBranch
es which they need to
move further and report their progress.Modifier and Type | Method and Description |
---|---|
Evaluation |
evaluate(TraversalBranch branch,
BranchState state)
Evaluates a
TraversalBranch whether or not to include it in the
result and whether or not to continue further down this branch or not. |
boolean |
isUnique(TraversalBranch branch)
Used for all except branches to check adherence to the traversal
uniqueness.
|
boolean |
isUniqueFirst(TraversalBranch branch)
Used for start branches to check adherence to the traversal uniqueness.
|
void |
relationshipTraversed()
Reports that one more relationship has been traversed in this
traversal.
|
void |
unnecessaryRelationshipTraversed()
Reports that one more relationship has been traversed, albeit
a relationship that hasn't provided any benefit to the traversal.
