What metrics does Understand have?
This list is intended to be comprehensive, but we do make errors. If you don't see a metric you want, it may be named differently, or we may have it but forgot to add it to this list, or we may need to add it. E-mail us and we can sort it out for you.
Language Key:
- A = Ada 83 or Ada 95
- C = C/C++
- F = FORTRAN
- J = Java
- P = Pascal
- V = Jovial
Column Header explanations:
- Understand API Metric Name - the name used to get the metric when programming with Understand's PERL or C/C++ API.
- Project - the metric is available as a measure for an entire project.
- File - metric available as measure for entire file.
- Function or Program Unit - metric is available as a measure for a function, method, or Program Unit.
- Class- metric is available as measure of a Class.
- Common Name - the name of the metric as described in most metrics literature. Not all metrics have this.
