It is the cyclomatic complexity, also known as McCabe metric. Whenever the control flow of a method function splits, the complexity counter gets incremented by one.
|Complexity /class||class_complexity||Average complexity by class.|
|Complexity /file||file_complexity||Average complexity by file.|
|Complexity /method||function_complexity||Average complexity by method function.|
A class afferent couplings is a measure of how many other classes use the specific class.
Depth in Tree
The depth of inheritance tree (DIT) metric provides for each class a measure of the inheritance levels from the object hierarchy top.
A class efferent couplings is a measure of how many different classes are used by the specific class.

The number of children of a class is the number of direct and indirect descendants of this classThis metric is available at directory level.
Minimal number of package directory cycles detected to be able to identify all undesired dependencies. This metric is available at directory, module and project level.
Package dependencies to cut
Number of package directory dependencies to cut in order to remove all cycles between packages.directories. This metric is available at the package, module and program levels.
Package tangle index
Level of tangle of the packagesdirectory interdependency. Best value (0%) means that there is no cycle and worst value (100%) means that packages directories are really tangled. This metric is computed with the following formula: 2 * (File dependencies to cut / Number of file dependencies between packagesdirectories) * 100.
Response for class
See RFC documentation pageThis metric is available at directory, module and project level.
Package edges weight
Number of file dependencies between packages.directories. This metric is available at directory, module and project level.
File dependencies to cut in order to remove cycles between files inside a packagedirectory. Note that cycles between files inside a package directory does not always mean a bad quality architecture.

|Technical debt||sqale_index||Effort in days to fix all issues.|
|Blocker||Operational/security risk: This issue might make the whole application unstable in production. Ex: calling garbage collector, not closing a socket, etc.|

On each line of code containing some boolean expressions, the branch coverage simply answers the following question: 'Has each boolean expression been evaluated both to true and false?'. This is the density of possible branches in flow control structures that have been followed during unit tests execution.
