All Implemented Interfaces:

QuerydslPredicateExecutor<T>

@API(status=INTERNAL,
     since="6.1")
public final class QuerydslNeo4jPredicateExecutor<T>
extends Object
implements QuerydslPredicateExecutor<T>

Querydsl specific fragment for extending SimpleNeo4jRepository with an implementation of QuerydslPredicateExecutor. Provides the necessary infrastructure for translating Query-DSL predicates into conditions that are passed along to the Cypher-DSL and eventually to the template infrastructure. This fragment will be loaded by the repository infrastructure when a repository is declared extending the above interface.

Since:

6.1
