initAll

protected final void initAll(String whereString,
                             String orderByString,
                             LockOptions lockOptions)
                      throws MappingException

抛出:

MappingException

initAll

protected final void initAll(String whereString,
                             String orderByString,
                             LockOptions lockOptions,
                             JoinWalker.AssociationInitCallback callback)
                      throws MappingException

抛出:

MappingException

initProjection

protected final void initProjection(String projectionString,
                                    String whereString,
                                    String orderByString,
                                    String groupByString,
                                    LockOptions lockOptions)
                             throws MappingException

抛出:

MappingException

getWhereFragment

protected String getWhereFragment()
                           throws MappingException

抛出:

MappingException

isJoinedFetchEnabled

protected boolean isJoinedFetchEnabled(AssociationType type,
                                       FetchMode config,
                                       CascadeStyle cascadeStyle)

The superclass deliberately excludes collections

覆盖:

isJoinedFetchEnabled 在类中 JoinWalker

isJoinFetchEnabledByProfile

protected final boolean isJoinFetchEnabledByProfile(OuterJoinLoadable persister,
                                                    PropertyPath path,
                                                    int propertyNumber)

getComment

public abstract String getComment()

isDuplicateAssociation

protected boolean isDuplicateAssociation(String foreignKeyTable,
                                         String[] foreignKeyColumns)

从类复制的说明: JoinWalker

Used to detect circularities in the joined graph, note that this method is side-effecty

覆盖:

isDuplicateAssociation 在类中 JoinWalker

getPersister

public final Loadable getPersister()

getAlias

public final String getAlias()

orderBy

protected String orderBy(List associations,
                         String orderBy)

For entities, orderings added by, for example, Criteria#addOrder need to come before the associations' @OrderBy values. However, other sub-classes of JoinWalker (BasicCollectionJoinWalker, OneToManyJoinWalker, etc.) still need the other way around. So, override here instead. See HHH-7116.

覆盖:

orderBy 在类中 JoinWalker

toString

public String toString()

覆盖:

toString 在类中 Object
