Non-templatized classes and class template specializations for implementing function objects that are used in various places in ACE. There are currently two major categories of function objects in ACE: GoF Command Pattern objects, and STL-style functors for comparison of container elements. The command objects are invoked via an execute () method, while the STL-style functors are invoked via an operator() () method. Non-templatized classes for implementing the GoF Command Pattern, also known as functors or function objects.
