    • Method Detail

      • copy

        default T copy()
        Make a deep copy of the object, with all new instances. Implementations should use apply(Object) to apply this values to the new instance. Default implementation returns null. 
         @Override
 public Budget copy() {
        final Budget copy = new Budget();
        copy.apply(this);
        return copy;
 }
        Returns:
        a deep copy

      • apply

        default T apply​(T source)
        Apply values from source to this object. It should not handle lists, sets and other complicated things. The default implementation is based on ReflectionUtils.shallowCopyFieldState(Object, Object) but it only uses accessible fields and ignores Collections.
        Parameters:
        source - the source
        Returns:
        the t

      • copyList

        default <R extends Copyable<R>> List<R> copyList​(List<R> source,
                                                 Consumer<? super R> action)
        Utility method that makes a deep copy of Copyable elements.
        Type Parameters:
        R - the generic type
        Parameters:
        source - the source
        action - the action
