Release v2023.1.33

Type-safe SQL

  • Query types are instantly available as you type native SQL of any complexity in your Java code
  • Schema types are automatically derived from your database, providing type-safe CRUD, decoupled TX, and more
  • No ORM, No DSL, No wiring, and No code generation build steps

Tuple expressions

Tuple expressions provide concise syntax to group named data items in a lightweight structure.

var t = (name: "Bob", age: "35");
System.out.println("Name: " + t.name + " Age: " + t.age);

var t = (person.name, person.age);
System.out.println("Name: " + t.name + " Age: " + t.age);

Forwarding and True Delegation

Favor composition over inheritance. Use @link and @part for automatic interface implementation forwarding and delegation.

class MyClass implements MyInterface {
  @link MyInterface myInterface; // transfers calls on MyInterface to myInterface

  public MyClass(MyInterface myInterface) {
    this.myInterface = myInterface; // dynamically configure behavior
  }

  // No need to implement MyInterface here, but you can override myInterface as needed
}

auto type inference

  • auto type inference for local vars, fields, and method return types
  • Enables multiple return values for methods
import manifold.ext.rt.api.auto;

var result = findMinMax(data);
System.out.println("Minimum: " + result.min + " Maximum: " + result.max);

auto findMinMax(int[] data) {
  if(data == null || data.length == 0) return null;
  int min = Integer.MAX_VALUE;
  int max = Integer.MIN_VALUE;
  for(int i: data) {
    if(i < min) min = i;
    if(i > max) max = i;
  }
  return min, max;
}

Multidimensional index operator

Property inference on record types

Java 21 Support

IntelliJ IDEA & Android Studio plugin improvements

  • Comprehensive support for all new features including type-safe SQL, forwarding & delegation, tuples, etc.
  • Many performance improvements and bug fixes toward an improved user experience in the IDE
  • Support IDEA Chinese Language Pack

Fixes & feature requests
