Coupled Packages

API ID: CountPackageCoupled
Languages: Ada
Targets: Packages

Number of other packages coupled to.

Package A is coupled to package B if package A depends on (Ada's with) something declared in package B. Only the depending package counts the coupling — the package being depended on doesn't count as coupled to its dependents.

For example:

with Essential_Demo;

package Essential_Helper is

   procedure Use_Essential (X : in out Integer);

end Essential_Helper;

Essential_Helper depends on Essential_Demo (calling Essential_Demo.Simple_Proc), giving Essential_Helper's CountPackageCoupled = 1. Essential_Demo itself has no dependencies of its own, so its CountPackageCoupled = 0, even though another package depends on it.

This is the package-level counterpart to Coupled Classes (Chidamber & Kemerer's CBO), which measures the same kind of coupling between classes.
