Example 1 with IAccessControlService

use of org.eclipse.scout.rt.shared.services.common.security.IAccessControlService in project scout.rt by eclipse.

the class AbstractSqlService method execCustomBindFunction.

/**
 * Custom functions that can be used in sql statements as binds or sql style independent functions
 * <p>
 * Default functions are<br>
 * ::level(permissionClass) --> int //to resolve a permissin level by executing a permission<br>
 * ::level(permissionLevel) --> int //to resolve a permissin level by its id<br>
 * ::code(codeClass or codeTypeClass) --> the ID of the code or code type<br>
 * ::text(textId) --> the text in the user sessions language
 * <p>
 * Examples:<br>
 * ::level(UpdatePersonPermission)<br>
 * ::level(UpdatePersonPermission.LEVEL_OWN)<br>
 * <br>
 * ::code(CompanyAddressCodeType.MainAddressCode)<br>
 * ::code(MainAddressCode)<br>
 * <br>
 * ::text(SalutationMr)
 * <p>
 *
 * @return a plain object value or in case of a null value preferrably a {@link IHolder} of the correct value type
