类 FetchProfile

  • public class FetchProfile
extends Object
    A 'fetch profile' allows a user to dynamically modify the fetching strategy used for particular associations at runtime, whereas that information was historically only statically defined in the metadata.

    This class defines the runtime representation of this data.
