SubselectFetch

public SubselectFetch(String alias,
                      Loadable loadable,
                      QueryParameters queryParameters,
                      Set resultingEntityKeys,
                      Map namedParameterLocMap)

Construct a SubselectFetch instance. The subselect fetch query fragment is generated by createSubselectFetchQueryFragment(org.hibernate.engine.spi.QueryParameters). If the same value for queryParameters is to be used when constructing multiple SubselectFetch objects, then it is preferable to generate the subselect fetch query fragment using createSubselectFetchQueryFragment(org.hibernate.engine.spi.QueryParameters), and pass the result as an argument to constructor SubselectFetch(String, String, Loadable, QueryParameters, Set, Map).

参数:

alias - - the table alias used in the subselect fetch query fragment (to be generated by createSubselectFetchQueryFragment(QueryParameters) that corresponds to loadable;

loadable - - the Loadable for the associated entities to be subselect fetched;

queryParameters - - the query parameters;

resultingEntityKeys - - the EntityKey objects for the entities to be subselect fetched;

namedParameterLocMap - - mapping from named parameter to the parameter index located in the subselect fetch query fragment.

SubselectFetch

public SubselectFetch(String subselectFetchQueryFragment,
                      String alias,
                      Loadable loadable,
                      QueryParameters queryParameters,
                      Set resultingEntityKeys,
                      Map namedParameterLocMap)

Construct a SubselectFetch instance using the provided subselect fetch query fragment, subselectFetchQueryFragment. It is assumed that subselectFetchQueryFragment is the result of calling createSubselectFetchQueryFragment(org.hibernate.engine.spi.QueryParameters) with the same value provided for queryParameters.

参数:

subselectFetchQueryFragment - - the subselect fetch query fragment;

alias - - the table alias used in subselectFetchQueryFragment that corresponds to loadable;

loadable - - the Loadable for the associated entities to be subselect fetched;

queryParameters - - the query parameters;

resultingEntityKeys - - the EntityKey objects for the entities to be subselect fetched;

namedParameterLocMap - - mapping from named parameter to the parameter index located in the subselect fetch query fragment.
