Programmatically override or completely redefine fetching at runtime through API and queries:

* Criteria respects the laziness settings in your mappings and guarantees that what you want loaded is loaded. This means one Criteria query might result in several SQL immediate SELECT statements to fetch the subgraph with all non-lazy mapped associations and collections. If you want to change the "how" and even the "what", use setFetchMode() to enable or disable outer join fetching for a particular collection or association. Criteria queries also completely respect the fetching strategy (join vs select vs subselect).

* HQL respects the laziness settings in your mappings and guarantees that what you want loaded is loaded. This means one HQL query might result in several SQL immediate SELECT statements to fetch the subgraph with all non-lazy mapped associations and collections. If you want to change the "how" and even the "what", use LEFT JOIN FETCH to enable outer-join fetching for a particular collection or nullable many-to-one or one-to-one association, or JOIN FETCH to enable inner join fetching for a non-nullable many-to-one or one-to-one association. HQL queries do not respect any fetch="join" defined in the mapping document.

* At the moment no batch or subselect fetching override is available dynamically. Both Criteria and HQL respect the settings defined in the mapping document if additional SELECT statements must be executed to load the non-lazy mapped associations and collections.

Hy all

I'd like to know if there is a way of forcing non-laziness from the code (other than explicitly calling all the getters).

I'd like most of my association to be lazily loaded when running in the server but forcing a full load before sending a graph of object to the client where my session will have disappeared and so will generate an error.

thanks

Note: This only ensures intialization of a proxy object or collection; it is not guaranteed that the elements INSIDE the collection will be initialized/materialized.
