// Class : ConfigVariableEnum
|
|
// Description : This class specializes ConfigVariable as an
|
|
// enumerated type. It is a template class, so it
|
|
// cannot be easily published; it's not really necessary
|
|
// outside of C++ anyway.
|
|
//
|
|
// This variable assumes that the enumerated type in
|
|
// question has input and output stream operators
|
|
// defined that do the right thing (outputting a
|
|
// sensible string for the type, and converting a string
|
|
// to the correct value).
