Class EntityAccessManager

java.lang.Object

org.neo4j.ogm.entity.io.EntityAccessManager

public class EntityAccessManager
extends Object

Determines how entities should be accessed in both reading and writing scenarios by looking 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.
