Métriques de code

Descriptions et exemples de métriques de code

Lorsque Polyspace® Bug Finder™ analyse votre code, vous pouvez choisir de calculer des statistiques à propos de votre programme. Utilisez l'option d’analyse Calculate code metrics (-code-metrics) pour activer le contrôle des métriques de code. Pour comprendre les différents résultats des métriques de code et la manière dont Bug Finder les calcule, consultez ces pages de référence.

Polyspace Bug Finder ne supporte pas le calcul des métriques d'utilisation des piles. Pour calculer les métriques d'utilisation des piles, utilisez Polyspace Code Prover™. Consultez Calculate stack usage (-stack-usage) (Polyspace Code Prover).
