Metrics Summary

The scope of the metrics report depends on the selection made in the Report Explorer window. This can be a file, one or several classes or any other set of source code components.

Below the Halstead graph, the Root page displays a metrics summary table, which lists for for the source code component of the selected scope:

V(g): provides a complexity estimate of the source code component
Statements: shows the number of statements within the component
Nested Levels: shows the highest nesting level reached in the component

Ext Var Use: measures the number of uses of attributes defined outside of the component class (C++)
