Examples of com.db4o.ObjectContainer.store()

com.db4o.ObjectContainer.store()

newly stores objects or updates stored objects.

An object not yet stored in the ObjectContainer will be stored when it is passed to store(). An object already stored in the ObjectContainer will be updated.

Updates
- will affect all simple type object members.
- links to object members that are already stored will be updated.
- new object members will be newly stored. The algorithm traverses down new members, as long as further new members are found.
- object members that are already stored will not be updated themselves.
Every object member needs to be updated individually with a call to store() unless a deep {@link com.db4o.config.Configuration#updateDepth global} or {@link com.db4o.config.ObjectClass#updateDepth class-specific}update depth was configured or cascaded updates were {@link com.db4o.config.ObjectClass#cascadeOnUpdate defined in the class}or in {@link com.db4o.config.ObjectField#cascadeOnUpdate one of the member fields}. Depending if the passed object is newly stored or updated, Creating/Created or Updating/Updated callback method is triggered. Callbacks might also be used for cascaded updates.
