从类复制的说明: JoinWalker

Determine the appropriate type of join (if any) to use to fetch the given association.

覆盖:

getJoinType 在类中 JoinWalker

参数:

persister - The owner of the association.

path - The path to the association

propertyNumber - The property number representing the association.

associationType - The association type.

metadataFetchMode - The metadata-defined fetch mode.

metadataCascadeStyle - The metadata-defined cascade style.

lhsTable - The owner table

lhsColumns - The owner join columns

nullable - Is the association nullable.

currentDepth - Current join depth

返回:

type of join to use (JoinType.INNER_JOIN, JoinType.LEFT_OUTER_JOIN, or -1 to indicate no joining.

抛出:

MappingException - ??

getComment

public String getComment()

指定者:

getComment 在类中 AbstractEntityJoinWalker

getCompositeKeyManyToOneTargetIndices

public int[][] getCompositeKeyManyToOneTargetIndices()
