Activation Conditions (prepare): +// - The tweak activates when the cursor is over a C++ class definition. +// - The class must be abstract (it, or its base classes, have unimplemented +// pure virtual functions). +// - It must also inherit from at least one other abstract class. +// +// 2. Identifying Missing Methods: +// - The tweak scans the inheritance hierarchy of the current class. +// - It identifies all unique pure virtual methods from base classes +// that are not yet implemented or overridden. +// - These missing methods are then grouped by their original access +// specifier (e.g., public, protected). +// +// 3. Code Generation and Insertion: +// - For each group of missing methods, stubs are inserted. +// - If an access specifier section (like `public:`) exists, stubs are +// inserted there; otherwise, a new section is created and appended. +// - Each generated stub includes the `override` keyword, a `// TODO:` +// comment, and a `static_assert(false, ...)` to force a compile-time +// error if the method remains unimplemented. +// - The base method's signature is adjusted (e.g., `virtual` and `= 0` +// are removed for the override). +// +// 4. Code Action Provided: +// - A single code action titled "Override pure virtual methods" is offered. +// - Applying this action results in a single source file modification +// containing all the generated method stubs. +// +// Example: +// +// class Base { +// public: +// virtual void publicMethod() = 0;
