@API(status=INTERNAL,
     since="6.0")
public final class PreparedQuery<T>
extends Object

Typed preparation of a query that is used to create either an executable query. Executable queries come in two fashions: imperative and reactive. Depending on which client is used to retrieve one, you get one or the other.

When no mapping function is provided, the Neo4j client will assume a simple type to be returned. Otherwise, make sure that the query fits to the mapping function, that is: It must return all nodes, relationships and paths that is expected by the mapping function to work correctly.

Since:
