createCoalescedDisplayNameExpression

public static javax.persistence.criteria.Expression<String> createCoalescedDisplayNameExpression(javax.persistence.criteria.CriteriaBuilder cb,
                                                                                                 javax.persistence.criteria.From<?,Projekt> projectFrom,
                                                                                                 Locale locale)

Creates an expression to coalesce the display name of a project, handling localization fallbacks.

The display name is coalesced in the following order:

1. Given locale localization
2. Default locale localization
3. Project title

The given locale localization is determined by the given locale, the default locale localization is determined by the project's default locale, and the project title is the default display name.

Parameters:

cb - Criteria builder to create the expression

projectFrom - Project root to create the expression from

locale - Locale to filter by

Returns:

Expression to coalesce the display name of a project

createCoalescedShortDescriptionExpression

public static javax.persistence.criteria.Expression<String> createCoalescedShortDescriptionExpression(javax.persistence.criteria.CriteriaBuilder cb,
                                                                                                      javax.persistence.criteria.From<?,Projekt> projectRoot,
                                                                                                      Locale locale)

Creates an expression to coalesce the short description of a project, handling localization fallbacks.

The short description is coalesced in the following order:

1. Given locale localization
2. Default locale localization

The given locale localization is determined by the given locale, and the default locale localization is determined by the project's default locale.

Parameters:

cb - Criteria builder to create the expression

projectRoot - Project root to create the expression from

locale - Locale to filter by

Returns:

Expression to coalesce the short description of a project
