Method Detail

applyLocksback to summary
protected String applyLocks(String sqlSelectString, LockOptions lockOptions, Dialect dialect) throws QueryException

Overrides org.hibernate.loader.Loader.applyLocks.

Doc from org.hibernate.loader.Loader.applyLocks.

Append FOR UPDATE OF clause, if necessary. This empty superclass implementation merely returns its first argument.

protected boolean areResultSetRowsTransformedImmediately(ResultTransformer transformer)

Overrides org.hibernate.loader.Loader.areResultSetRowsTransformedImmediately.

Doc from org.hibernate.loader.Loader.areResultSetRowsTransformedImmediately.

Are rows transformed immediately after being read from the ResultSet?

Parameters
transformer:ResultTransformer

the specified transformer

Returns:boolean

true, if getResultColumnOrRow() transforms the results; false, otherwise

Overrides org.hibernate.loader.Loader.getResultColumnOrRow.

Doc from org.hibernate.loader.Loader.getResultColumnOrRow.

Get the actual object that is returned in the user-visible result list. This empty implementation merely returns its first argument. This is overridden by some subclasses.
