ScopedCollection_test Class Reference

Description

Test:

ScopedCollection manages a fixed set of objects, but these child objects are noncopyable, may be polymorphic, an can be created either all at once or chunk wise. The API is similar to a vector and allows for element access and iteration.

Test:

using the ScopedCollection to hold a variable and possibly increasing number of elements, within the fixed limits of the maximum capacity defined by the ctor parameter. Any new elements will be created behind the already existing objects. In case of failure while creating an element, only this element gets destroyed, the rest of the container remains intact.

building_RAII_Style()

void building_RAII_Style ( )

inlineprivate

Test:

using the ScopedCollection according to the RAII pattern. For this usage style, the collection is filled right away, during construction. If anything goes wrong, the whole collection is cleared and invalidated. Consequently there is no tangible "lifecycle" at the usage site. Either the collection is fully usable, or not at all. This requires the client to provide a functor (callback) to define the actual objects to be created within the ScopedCollection. These may as well be subclasses of the base type I, provided the general element storage size #siz was chosen sufficiently large to hold those subclass instances.

This test demonstrates the most elaborate usage pattern, where the client provides a full blown functor object #Populator, which even has embedded state. Generally speaking, anything exposing a suitable function call operator is acceptable.

Test:

for using ScopedCollection in RAII style, several pre-defined "populators" are provided. The most obvious one being just to fill the collection with default constructed objects.

Test:

simulate the typical situation of a manager owning some embedded components. Here, our ManagerDemo instance owns a collection of numbers 50..1. They are created right while initialising the manager, and this initialisation is done by invoking a member function of the manager
