NOT FOR GENERAL USE ObjectContainerBase function overloads.
The implementation of these methods ensure the behaviour of the class as a type of class ObjectContainerBase. This base class and its behaviour are only used by "generic" object handlers. These classes collaborate with several classes such as the SmartRef classes. Generic converters. Interfaces for interactivity (e.g. Python) For this reason, the entry points in this section are reserved for "generic" object handling and should NOT be used in public.

Sequential array access to objects using iterators.
Sequential object access using iterators is much faster then object access by key. In case all objects of the container should be addressed, use iterators rather than direct object access. If the container is accessed through the iterators defined below, the elements may be sorted according to the user needs. The container can be accesses in both const and non-const mode. Iterations are supported in both directions: From the beginning to the end and the reverse.

Random access to objects in the container.
Access to objects is given by Key. Please note, that random object access is nearly in all cases significantly slower than sequential access.

## Detailed Description

### template<class DATATYPE, class MAPPING = Containers::HashMap>
class KeyedContainer< DATATYPE, MAPPING >

template class KeyedContainer, KeyedContainer.h

This class represents a container, where the contained objects are accessed by a key. Such a key can be any class, which is able to convert to and from a 32-bit (long) integer.

To insert objects into the container, this implementation determines the key in the following way:

- If the object is already keyed, the object's key is kept and cannot be modified.
- If the object is NOT keyed, and a key is supplied, this key is used to register the object in the map and the same key is given to the object.
- If the object is NOT keyed, and NO key is supplied, a key is generated by the map implementation and this key is given to the object.
- It is not possible to insert two objects with the same key into the same container. This causes an exception.

Access to objects is given two-fold:

- Using iterators. This access is very efficient. The container however, may not be manipulated: No objects may not be inserted or removed using iterators.
- Using object keys: This access patterns provides random access to objects.

The KeyedContainer class uses for further specialization a traits class. By specializing these traits extra behaviour can be forced on request for special containers or special keys.

Returns
  Enumeration value from the Containers namespace:

  - OBJ_NOT_FOUND: The indicated object was not found in the container
  - OBJ_ERASED: The indicated object was found and removed from the container. The object was not yet deleted, because its reference count was non zero.

Remove/erase object (identified by iterator) from the container.

This member function removes an object, which is identified by its reference from the container. No key value is supplied. To identify the object within the container, the key of the object is used as it can be retrieved using the KeyedObject::key() method.

  val | Reference to object to be removed from the container.

Returns
  Enumeration value from the Containers namespace:
  - OBJ_NOT_FOUND: The indicated object was not found in the container
  - OBJ_ERASED: The indicated object was found and removed from the container. The object was not yet deleted, because its reference count was non zero.
  - OBJ_DELETED The indicated object was found and removed from the container. The object was deleted, because its reference count was zero.

const KeyedContainer< DATATYPE, MAPPING >::key_type & KeyedContainer< DATATYPE, MAPPING >::insert | ( | const value_type | val,
|  | const key_type & | kval
| ) |  |
| inline

Insert entry to the container with a valid key.

This member function inserts an element, which is identified by its reference to the container. The element will be inserted using the specified key. If the object is already keyed, the long representations of the supplied key and the object's key must agree.

The object will not be inserted and an exception will be raised under the following conditions:

- The supplied key does not agree with the object's key.
- An object with the supplied key is already present in the container.

Parameters

  val | Reference to object to be inserted into the container. The object reference may NOT be NULL.
  kval | Key to identify the object within the container.

Returns
  Key, which was used to index the object within the container. If the operation is not successful, an exception is thrown.

const KeyedContainer< DATATYPE, MAPPING >::key_type & KeyedContainer< DATATYPE, MAPPING >::insert | ( | const value_type | val | ) |

Insert entry to the container with automatic key assignment.

This member function inserts an element, which is identified by its reference to the container. No key value is supplied. The key used to insert the object is retrieved from the element itself. In the event the object already has a key, the assigned key of the object is used. If no key was assigned to the object, (i.e. the object's key is equal to the invalid key), a key is generated according to the number of objects present in the container.

The object will not be inserted and an exception will be raised under the following conditions:

- A key was already assigned to the object, but another object with the same key is already present in the container.

Parameters

  val | Reference to object to be inserted into the container.

Returns
  Key, which was used to index the object within the container. If the operation is not successful, an exception is thrown.

long KeyedContainer< DATATYPE, MAPPING >::remove | ( | ContainedObject * | pObject | ) |

ObjectContainerBase overload: Remove an object from the container.

Because this function is also called from the destructor of The ContainedObject class, it is no longer possible to deduce the key from the object itself. It is hence necessary to relay on the NON-EXISTENCE of virtual inheritance, ie. (void*)pObject = (void*)(contained_object). If the virtual object table is still intact, the normal erase is called.

Parameters

  pObject | Pointer to the object to be removed from the container.

Implements ObjectContainerBase.
