Example 91 with FieldInfo

use of org.neo4j.ogm.metadata.FieldInfo in project neo4j-ogm by neo4j.

the class EntityAccessManagerTest method shouldPreferFieldBasedOnRelationshipTypeToPlainSetterWithMatchingParameterType.

@Test
public void shouldPreferFieldBasedOnRelationshipTypeToPlainSetterWithMatchingParameterType() {
    // 4th, try to find a "XYZ" field name where XYZ is derived from the relationship type
