Do the following annotations @OneToMany @ManyToOne @ ManyToMany @OneToOne imply @Index   ? Thanks, Carl   FastModel Ben Schreiber Actually these annotations (except @ ManyToMany ) should apply @Unique on the @One side. But ObjectDB doesn't apply these indexes automatically

public class ProductSet implements Serializable { @ ManyToMany (fetch = FetchType.EAGER, cascade ... Serializable, Convertable { @ ManyToMany (targetEntity = ProductSet.class, mappedBy = "productDemands

Given that the default seems to be FetchType.LAZY for all collections @OneToMany and @ ManyToMany . Such as a configuration option. Instead of having to explicitly set fetch in annotation code in every relationship. webel Dr Darren Kelly No. There is no such configuration option, since having EAGER

hi,   what is the purpose of annotating a field with a RDB relationship shuch as OneToMany. ManyToMany etc? sprintf Reuben Alfred Using these annotations is optional in ObjectDB but required by standard JPA. You still need these annotations in ObjectDB to specify cascading / fetch policy and other settings. support Support

I'm having an issue eager loading a nested map. I've attached @ ManyToMany (fetch=FetchType.EAGER) attributes to no avail. If the map is viewed in the debugger or force iterated in the code it loads ok. The attached code attempts to replicate the scenario. Its not an exact match but is the best I
