Method Detail

selectFragment

String selectFragment(String alias,
                      String columnSuffix)

Generate a list of collection index and element columns

getIndexColumnNames

String[] getIndexColumnNames()

Get the names of the collection index columns if this is an indexed collection (optional operation)

getIndexFormulas

String[] getIndexFormulas()

Get the index formulas if this is an indexed collection (optional operation)

getIndexColumnNames

String[] getIndexColumnNames(String alias)

Get the names of the collection index columns if this is an indexed collection (optional operation), aliased by the given table alias

getElementColumnNames

String[] getElementColumnNames(String alias)

Get the names of the collection element columns (or the primary key columns in the case of a one-to-many association), aliased by the given table alias

getElementColumnNames

String[] getElementColumnNames()

Get the names of the collection element columns (or the primary key columns in the case of a one-to-many association)

getSQLOrderByString

String getSQLOrderByString(String alias)

Get the order by SQL

getManyToManyOrderByString

String getManyToManyOrderByString(String alias)

Get the order-by to be applied at the target table of a many to many

Parameters:

alias - The alias for the many-to-many target table

Returns:

appropriate order-by fragment or empty string.

hasWhere

boolean hasWhere()

Does this collection role have a where clause filter?

getElementPersister

EntityPersister getElementPersister()

Get the persister of the element class, if this is a collection of entities (optional operation). Note that for a one-to-many association, the returned persister must be OuterJoinLoadable.

getFetchMode

FetchMode getFetchMode()

Should we load this collection role by outerjoining?
