@Data

Composite data-class helper: getters, setters (non-readonly fields), equals, and toString via codegen.

Kind	Codegen
Backends	legacy, stage3
Requires generate	Yes

When to use

• Plain data holders (DTOs, entities, config objects) where you want Lombok-style accessors without hand-writing them
• Together with @Builder for fluent construction

When not to use

• Classes with complex invariant logic in constructors (v0.1 does not inject a generated constructor)
• When you only need toString — use @ToString alone

Example

import { Data } from 'lombok-typescript/legacy';

@Data
export class User {
  name!: string;
  readonly id!: string;
  age?: number;
}

lombok-ts generate

import { User } from './user.js';
import { applyAllGenerated } from '../.lombok/src/user.lombok.js';

applyAllGenerated({ User });

const u = new User();
u.name = 'Ada';
u.getName(); // generated getter

Codegen steps

1. lombok-ts generate emits accessor functions and applyUserGenerated.
2. Include .lombok/**/*.ts and .lombok/**/*.d.ts in tsconfig.
3. Call applyAllGenerated({ User }) once at startup.

v0.1 limitations

• Does not replace or auto-wire a multi-argument constructor; assign fields after new User() or use @Builder.
• readonly fields get getters only (no setter) in generated code.
• equals uses referential field equality (===), not deep comparison.
