/**
* 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
