The codeanalyzer backends

Source parsing, symbol resolution, and call-graph construction are performed by standalone language analyzers, one per language, collectively the codeanalyzer-* backends. Each backend emits typed JSON, and the SDK deserializes it into queryable models.

This separation lets a single analysis API span languages. The SDK does not parse code itself; it invokes the appropriate backend, then maps the backend JSON onto typed models (JApplication, PyModule, and others). A backend that emits the canonical JSON makes its language available to the SDK with only binding work required. See Add a language backend.

Backends are managed by the SDK

The SDK manages the backend automatically: each codeanalyzer-* backend binary ships with its packaged PyPI dependency (the JVM-free Java backend runs via python -m codeanalyzer_java; the TypeScript binary ships in codeanalyzer-typescript), and the Python analyzer is provisioned in a virtualenv. There is no separate JAR download or analysis_backend_path override. These pages document the backend layer for readers who want to understand or contribute to it.

This is the backend layer. For the SDKs that consume it, see the SDKs overview.

Backends (analyzers)

The codeanalyzer-* tools parse a language and serialize the canonical symbol-table and call-graph schema that every frontend reads.

Built backends

codeanalyzer-python Jedi-based semantic analysis with optional CodeQL call-graph augmentation; emits the canonical Py* schema.

codeanalyzer-java WALA and Javaparser; produces symbol tables, call graphs, type hierarchy, and CRUD analysis.

codeanalyzer-ts Beta. The TypeScript/TSX analyzer, emitting the canonical symbol-table and call-graph schema; entrypoint detection is still in progress.

Add a backend Help wanted. Go, Rust, C, C++, and C# are not yet built. A backend that emits the canonical JSON makes that language available to every SDK.
