permethod

Permethod is a loosely defined term in software engineering used to describe behaviors or settings that are attached to individual methods rather than to classes, modules, or the system as a whole. Because there is no formal standard, its exact meaning depends on the context.

Common usages include per-method configuration, where each method may specify its own logging level, error handling strategy, or feature flags; per-method instrumentation, where tracing or timing data is collected for each method independently; per-method access control, where permissions are evaluated on a per-method basis; and per-method caching, where results are cached keyed by method and input signature.

In practice, permethod concepts appear in aspect-oriented programming, middleware, microservices, and runtime observability tools. They can help tailor performance and security policies to specific code paths but may increase complexity and maintenance overhead.

Some organizations use terms like method-level, per-method, or per-endpoint interchangeably; others maintain stricter interpretations tied to a given framework's configuration model.

Implementation considerations include performance impact, consistency of policy, testing requirements, and potential disagreements about where such concerns should be defined.
