METRICS.CIHL

"class" or "Interface" inheritance level

This metric measures "class" or "interface" inheritance level.

An unnecessarily deep class hierarchy adds to complexity and can represent a poor use of the inheritance mechanism.

By default, Jtest reports an error if this metric's value is not between 0 and 5.
