Name

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.
