// Class : CPPInstanceIdentifier
|
|
// Description : This class is used in parser.y to build up a variable
|
|
// instance definition. An instance is something like
|
|
// 'int *&a'; the InstanceIdentifier stores everything
|
|
// to the right of the typename. Later this can be
|
|
// passed to make_instance() to construct a CPPInstance.
