Glossary: IsA
When one
class,
say class X
inherits
from another, say class Y, then the relationship between them is sometimes
described as "X IsA Y". For example a
TH2F
inherits (indirectly) from
TObject
so TH2F IsA TObject.
The IsA relationship can be contrasted with the
HasA
relationship, where one of a class's
data members
is another object.
