Annotation Type PersistenceFunction

@Retention(RUNTIME)
@Target(METHOD)
public @interface PersistenceFunction
Defines the persistence related rendering of a declaratively defined domain function as template string. The domain function arguments are rendered into placeholders. A function like @DomainFunction("IS_OLD") @FunctionExpression("?1.age > 18") static Boolean isOld(@DomainFunctionParam("person") User user) { return user.getAge() > 18; } will render for the use of the function like IS_OLD(me) to something like meJpqlAlias.age > 18
