Implements org.hibernate.IdentifierLoadAccess.disableFetchProfile.

Customize the associations fetched by specifying a fetch profile that should be disabled during this operation.

This allows the session-level fetch profiles to be temporarily overridden.

getReferenceback to summary
public final T getReference(Object id)

Implements org.hibernate.IdentifierLoadAccess.getReference.

Doc from org.hibernate.IdentifierLoadAccess.getReference.

Return the persistent instance with the given identifier, assuming that the instance exists. This method might return a proxied instance that is initialized on-demand, when a non-identifier method is accessed.

You should not use this method to determine if an instance exists; to check for existence, use load instead. Use this only to retrieve an instance that you assume exists, where non-existence would be an actual error.

Parameters
id:Object

The identifier for which to obtain a reference

Returns:T

the persistent instance or proxy

loadback to summary
public final T load(Object id)

Implements org.hibernate.IdentifierLoadAccess.load.

Doc from org.hibernate.IdentifierLoadAccess.load.

Return the persistent instance with the given identifier, or null if there is no such persistent instance. If the instance is already associated with the session, return that instance, initializing it if needed. This method never returns an uninitialized instance.

Parameters
id:Object

The identifier

Returns:T

The persistent instance or null

Returns:Optional<T>
