Entity nesting is not supported.

[CorvusYe]

Issue from qq feedback.

Such as:

List<ComplexEntity> path();

public class ComplexEntity {
    private Object v1;
    private Object e;
    private Object v2;
}

MATCH (v1)-[e: type1 | type2 ]->(v1)
RETURN v1, e, v2;

Expect: v1 、e and v2 are set into mapped entity at runtime.
