Joern Code Property Graph Analysis

Overview

Joern parses source code into a Code Property Graph (CPG) — AST + CFG + dataflow merged into one queryable graph. After a one-time build (~30s–several min depending on codebase size), all subsequent queries are interactive and avoid repeated grep/find/manual call-tracing.

Core principle: Pay the parse cost once, then ask the same codebase arbitrarily many structural / interprocedural questions instantly.
