isJoinedFetchEnabled

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

The superclass deliberately excludes collections

Overrides:

isJoinedFetchEnabled in class JoinWalker

isJoinFetchEnabledByProfile

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

getComment

public abstract java.lang.String getComment()

isDuplicateAssociation

protected boolean isDuplicateAssociation(java.lang.String foreignKeyTable,
                                         java.lang.String[] foreignKeyColumns)

Description copied from class: JoinWalker

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

Overrides:

isDuplicateAssociation in class JoinWalker

getPersister

public final Loadable getPersister()

getAlias

public final java.lang.String getAlias()

orderBy

protected java.lang.String orderBy(java.util.List associations,
                                   java.lang.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.

Overrides:

orderBy in class JoinWalker

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
