Class DefaultEntityAccessStrategy

java.lang.Object

org.neo4j.ogm.entityaccess.DefaultEntityAccessStrategy

All Implemented Interfaces:

EntityAccessStrategy

public class DefaultEntityAccessStrategy
extends Object
implements EntityAccessStrategy

Default implementation of EntityAccessStrategy that looks up information from ClassInfo in the following order.

1. Annotated Method (getter/setter)
2. Annotated Field
3. Plain Method (getter/setter)
4. Plain Field

The rationale is simply that we want annotations, whether on fields or on methods, to always take precedence, and we want to use methods in preference to field access, because in many cases hydrating an object means more than just assigning values to fields.
