The Cyclomatic Complexity is measured by summing the number of and
, or
and xor
operators, the number of
control flow statement like IF
, WHILE
, DO
, RETURN
… in the body of a class plus one for each
method. Even when the Cyclomatic Complexity of a class is very high, this complexity might be well distributed among all methods. Nevertheless, most
of the time, a very complex class is a class which breaks the Single Responsibility Principle and which should be re-factored to be split in several
classes.
