NamedObjectCont< T > Class Template Reference

#include <NamedObjectCont.h>

Detailed Description

template<class T>
class NamedObjectCont< T >

A map of named object pointers.

An associative storage (map) for objects (pointers to them to be exact), which do have a name. In order to get the stored objects as a list, each insertion/deletion sets the internal state value "myHaveChanged" to true, indicating the list must be rebuild.

Member Function Documentation

template<class T>
virtual bool NamedObjectCont< T >::add ( const std::string &  id,
T  item 
) throw () [inline, virtual]

Adds an item.

If another item with the same name is already known, false is reported and the item is not added.

Parameters:
[in] id The id of the item to add
[in] item The item to add
Returns:
If the item could been added (no item with the same id was within the container before)

template<class T>
bool NamedObjectCont< T >::erase ( const std::string &  id  )  throw () [inline]

Removes the named item from the container.

If the named object exists, it is deleted, the key is removed from the map, and true is returned. If the id was not known, false is returned.

Parameters:
[in] id The id of the item to delete
Returns:
Whether the object could be deleted (was within the map)
