Odin - A Dependency Injection Library

Odin is an Object Dependency Injection library for Java applications.

Important notes:

• Odin is currently in alpha stage
• We'll be adding more documentation as we go along
• For the annotations module, support for javax.inject is provided for most features defined there.

User documentation

Include in a Java project using Gradle:

// if you want annotations support
compile 'io.jcoder.odin:odin-annotations:0.2.1'

// if you want only the core
compile 'io.jcoder.odin:odin-core:0.2.1'

Example usage:

Assume you have 2 classes A and B where A depends on B:

@Singleton
public static class A {
    private final B b;

    public A(B b) {
        this.b = b;
    }
    
    @PostConstruct
    void initialize() {
        System.out.println("A is initialized");
    }
}

@Singleton
public static class B {
    @PostConstruct
    void initialize() {
        System.out.println("B is initialized");
    }
}

Then, to create an injection context that manages A and B you would do the following:

import static io.jcoder.odin.annotation.builder.AnnotationAwareRegistrationBuilder.annotated;

InjectionContext context = new DefaultInjectionContext();
context.register(annotated(A.class));
context.register(annotated(B.class));
context.initialize();
