Public Member Functions

virtual BaseItemgetItemAt (MLssize_t index)
 This virtual function is reimplemented from ListBase, where it returns 0 in any case (also in ListTemplate<T>, because the items are not necessarily BaseItems there).
virtual const BaseItemgetConstItemAt (MLssize_t index) const
 Same as getItemAt(MLssize_t index) for constant access.
virtual void insertItemAt (MLssize_t index, const BaseItem *item)
 This virtual function is reimplemented from ListBase, where it does nothing at all.
virtual void modifyItemAt (MLssize_t index, const BaseItem *item)
 This virtual function is reimplemented from ListBase, where it does nothing at all.
virtual void deleteItemAt (MLssize_t index)
 This virtual function is reimplemented from ListBase, where it does nothing at all.
virtual void selectItemAt (MLssize_t index)

Constructors
 BaseListTemplate ()
 Standard constructor, disables persistence.
 BaseListTemplate (bool persistance)
 Special constructor to explicitly enable/disable persistence.
Next-id support
virtual MLssize_t newId ()
 Get new unused id.
virtual void usedId (MLssize_t id)
 Notify list that id is used.
virtual void resetId ()
 Reset next id.
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.

virtual void doDeleteItem (MLssize_t index)
 Delete single item at position index and set the corresponding ActDelete action.
virtual void doInsertItem (MLssize_t index, const T &item)
 Insert item at position index, assign a new id value to the inserted item and set the corresponding ActInsert action.
virtual void doModifyItem (MLssize_t index, const T &item)
 Store item at position index and set the corresponding ActModify action.
virtual void doSelectItem (MLssize_t index)
 Select item at position index, or deselect if item == -1, and set the corresponding ActSelect action.
virtual void appendItem (const T &item)
 Appends an item to the list.
virtual void addStateToTree (TreeNode *parent) const
 Attaches the object state as children of the given parent node.
 ML_SET_ADDSTATE_VERSION (1)
 Set addState version number.
virtual void readStateFromTree (TreeNode *parent)
 Reads the object state from the children of the given parent node.

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.

virtual char * getItemState (typename ListTemplate< T >::const_iterator it) const
 Return a string representation of the item object.
virtual void setItemState (typename ListTemplate< T >::iterator it, const char *state)
 Initialize the item object from the string state.
virtual void clearItemState (typename ListTemplate< T >::iterator it, char *state) const
 Dispose the string state, which has been previously obtained by getItemState()

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).

Member Function Documentation

template<class T >
void ml::BaseListTemplate< T >::addStateToTree ( TreeNode parent) const [virtual]

Attaches the object state as children of the given parent node.

BE SURE TO INCREASE THE VERSION NUMBER IN THE DECLARATION AND ADAPT readStateFromTree() TO THE NEW VERSION WHILE KEEPING IT DOWNWARD- COMPATIBLE!

Reimplemented from ml::ListTemplate< T >.

template<class T>
void ml::BaseListTemplate< T >::appendItem ( const T &  item) [virtual]

Appends an item to the list.

Equivalent to list.doInsertItem(list->getSize(), item);
