19  \ingroup Roofitcore
20 
21 RooAbsArg is the common abstract base class for objects that
22 represent a value (of arbitrary type) and "shape" that in general
23 depends on (is a client of) other RooAbsArg subclasses. The only
24 state information about a value that is maintained in this base
25 class consists of named attributes and flags that track when either
26 the value or the shape of this object changes. The meaning of shape
27 depends on the client implementation but could be, for example, the
28 allowed range of a value. The base class is also responsible for
29 managing client/server links and propagating value/shape changes
30 through an expression tree. RooAbsArg implements public interfaces
31 for inspecting client/server relationships and
32 setting/clearing/testing named attributes.
