description Overview

Replace Type with Generic

When a piece of code handles multiple, but related, types (e.g., processing `List` and `List`), this refactoring allows you to generalize the type parameter, replacing the specific type with a generic placeholder `T`. This maximizes code reuse by abstracting the specific type while retaining type safety.

Extract Interface from Class

A specialized version of Extract Type, this tool specifically targets extracting the *public contract* of a class into an interface. It analyzes which methods are called externally versus which are internal implementation details, guiding the developer to define the minimal necessary public API contract. This is the safest way to prepare a class for dependency inversion.
