module

protected JpaModule module

repositoryConfig

protected JpaRepositoryConfig<T> repositoryConfig

Constructor Detail

JpaRepositoryBase

protected JpaRepositoryBase(JpaModule module,
                            JpaRepositoryConfig<T> repositoryConfig)

Method Detail

getUnique

protected static <D> D getUnique(java.util.List<D> list,
                                 java.lang.Object id)

fetchRelations

protected boolean fetchRelations(java.lang.String fieldName)

By default LookupIncludeBehavior.ALWAYS is in place and we let the relationship repositories load the relations. There is no need to do join fetches, which can lead to problems with paging (evaluated in memory instead of the db).

Parameters:

fieldName - of the relation to fetch

Returns:

relation will be eagerly fetched if true

filterQuerySpec

protected io.crnk.core.queryspec.QuerySpec filterQuerySpec(io.crnk.core.queryspec.QuerySpec querySpec)

filterQuery

protected <E> JpaQuery<E> filterQuery(io.crnk.core.queryspec.QuerySpec querySpec,
                                      JpaQuery<E> query)

filterExecutor

protected <E> JpaQueryExecutor<E> filterExecutor(io.crnk.core.queryspec.QuerySpec querySpec,
                                                 JpaQueryExecutor<E> executor)

filterTuples

protected java.util.List<Tuple> filterTuples(io.crnk.core.queryspec.QuerySpec querySpec,
                                             java.util.List<Tuple> tuples)

filterResults

protected io.crnk.core.resource.list.ResourceList<T> filterResults(io.crnk.core.queryspec.QuerySpec querySpec,
                                                                   io.crnk.core.resource.list.ResourceList<T> resources)

map

protected io.crnk.core.resource.list.ResourceList<T> map(java.util.List<Tuple> tuples)
