NamedRegistries

Description

The class NamedRegistries (see Figure C-7) manages all instances of TestFactoryRegistry and is responsible for their creation and destruction. It also keeps track of which instances of TestFactory have been destroyed , thus preventing multiple deletions.

NamedRegistries is a singleton: there is one and only one static instance of it. Thus, it has no constructor. A reference to the single NamedRegistries object is obtained using its static getInstance( ) method.

NamedRegistries belongs to the namespace CppUnit . It is declared and implemented in TestFactoryRegistry.cpp .
