1. The argument to the DECLARE_FACTORY_ENTRIES statement is the name of the
component library.
2. Each component within the library should be declared using one of the DECLARE_XXX
statements discussed in detail in the next Section.
18.4.1.2 Component declaration statements
The complete set of statements that are available for declaring components is given below. They
include those that support C++ classes in different namespaces, as well as for DataObjects or
ContainedObjects using the generic converters.
Listing 18.4 The available component declaration statements
DECLARE_ALGORITHM(X)
DECLARE_AUDITOR(X)
DECLARE_CONVERTER(X)
DECLARE_GENERIC_CONVERTER(X) [1]
DECLARE_OBJECT(X)
DECLARE_SERVICE(X)
DECLARE_NAMESPACE_ALGORITHM(N,X) [2]
DECLARE_NAMESPACE_AUDITOR(N,X)
DECLARE_NAMESPACE_CONVERTER(N,X)
DECLARE_NAMESPACE_GENERIC_CONVERTER(N,X)
DECLARE_NAMESPACE_OBJECT(N,X)
DECLARE_NAMESPACE_SERVICE(N,X)
Notes:
1. Declarations of the form DECLARE_GENERIC_CONVERTER(X) are used to declare the
generic converters for DataObject and ContainedObject classes. For DataObject
classes, the argument should be the class name itself (e.g. EventHeader), whereas for
ContainedObject classes, the argument should be the class name concatenated with
either List or Vector (e.g. CellVector) depending on whether the objects are
associated with an ObjectList or ObjectVector.
2. Declarations of this form are used to declare components from explicit C++ namespaces. The
first argument is the namespace (e.g. Atlfast), the second is the class name (e.g.
CellMaker).
