Constructor Detail

ProjectionBean

public ProjectionBean(List<String> fields,
                      boolean autoAliasing)

Parameters:

fields - the list of the field names

autoAliasing - if the fields should be autoaliased. See important note above

Method Detail

fieldList

public static org.hibernate.criterion.ProjectionList fieldList(List<String> fieldList,
                                                               boolean autoaliasing)

Parameters:

fieldList - a list of fields to retrieve Important Note : the projection are automatically aliased with the same name, you could have some problems when using restriction (column yX_ doesn't exists) see http://opensource.atlassian.com/projects/hibernate/browse/HHH-817. To avoid this problem you could disable aliasing .
activate auto-aliasing if you want to use aliasToBean Transformers. disable auto-aliasing if you want to add a restriction on a field that is in the fields list

Returns:

a new ProjectionList

beanFieldList

public static org.hibernate.criterion.ProjectionList beanFieldList(Class<?> clazz,
                                                                   String[] ignoreFields,
                                                                   boolean autoaliasing)

Parameters:

clazz - the class to inspect to retrieve the fields

ignoreFields - an array of fields that should be ignore

autoaliasing - if the fields should be auto-aliased See important note above

Returns:

a new ProjectionList
