List modification methods

These methods combine list modifications (via the STL vector interface) with the corresponding updates of the last action properties. They are provided for convenience when only a single modification is performed and the field to which the list might be connected is touched directly after this modification. Do not use these methods if several modifications are performed before the list field is touched.

List item persistence

List persistence is directly based on the persistence methods of the list item class. Hence, the following methods are mapped to the item class persistence methods.

std::string itemState (typename ListTemplate< T >::const_iterator it) const override
void setItemState (typename ListTemplate< T >::iterator it, const std::string &state) override
 Initialize the item object from the string state.

Detailed Description

template<class T>
class ml::BaseListTemplate< T >

Base object template list class for list item classes derived from BaseItem.

List class template (derived from ListTemplate) for list item classes derived from BaseItem. Persistence of the list is based on the corresponding methods of the list class. The list maintains a 'next id' feature to support unique item id's.

To implement an instance of BaseListTemplate with a given type T (where T must be a subclass of BaseItem), the following steps are necessary:

  • Derive a subclass from the template instance class BaseListTemplate<T>
  • Use the ML_CLASS_HEADER and ML_CLASS_SOURCE macros to implement the runtime type system for this class. In the ML_CLASS_SOURCE macro, use ListBase in the base class argument.
  • If persistence is desired for the new class, make sure to initialize the base class with BaseListTemplate<T>(true) in the constructor of the new class. This requires that the persistence methods are properly defined for the item class T.
  • IMPORTANT: Make sure that the item class T has proper copy constructor and assignment operator (these are used by the STL).
