20/** \class TMethodArg
21Each ROOT method (see TMethod) has a linked list of its arguments.
22This class describes one single method argument.
23The method argument info is obtained via the CINT api.
24See class TCling.
25
26The method argument information is used a.o. in the TContextMenu
27and THtml classes.

117/// To learn how to specify the data member to which the argument should
118/// "point", look at TMethod. This is TMethod which sets up fDataMember,
