Introduction

Android Library that provide simpler way to achieve modularity.

Compile System requirements

JDK 7+

Download

For Java project add in build.gradle file:

dependencies {
    compile 'com.github.snowdream.toybricks:annotation:(latest version)'
    annotationProcessor 'com.github.snowdream.toybricks:processor:(latest version)'
    compile 'com.github.snowdream:toybricks:(latest version)'
}

For Kotlin project add in build.gradle file:

kapt {
    generateStubs = true
}

dependencies {
    compile 'com.github.snowdream.toybricks:annotation:(latest version)'
    kapt 'com.github.snowdream.toybricks:processor:(latest version)'
    compile 'com.github.snowdream:toybricks:(latest version)'
}

Advantage

1. Support for Java and Kotlin
2. APT: Compile-Time Annotation Processing with Java
3. No need to configure proguard yourself
4. Smart checking for @Interface and @Implementation

Disadvantage

1. Singleton class for kotlin start with object is not supported.

Usage

For interface, annotate it with @Interface

@Interface
public interface IText {

    String getText();
}

For default implementation, annotate it with @Implementation, and implements the defined Interface.

@Implementation(IText.class/*,singleton = true*/)
public class NewTextImpl implements IText {
    @Override
    public String getText() {
        return "NewTextImpl Implementation from "+ getClass().getCanonicalName();
    }
}

For global implementation, annotate it with @Implementation, and implements the defined Interface.

@Implementation(value = IText.class,global = true/*,singleton = true*/)
public class NewTextGobalImpl implements IText {
    @Override
    public String getText() {
        return "NewTextImpl Implementation from "+ getClass().getCanonicalName() ;
    }
}

Now, You can get the implementation for the interface as follows:

IText text = ToyBricks.getImplementation(IText.class);

Attention

1. For one interface, You can have only one default implementation and only one global implementation at the same time.
2. For interface,it should be public.
3. For implementation, it should be public,but not be abstract. it should inherit from the interface, and provide an empty public constructor.
4. You can add singleton = true to define Singleton for java and kotlin
5. Global implementation has the higher priority than default implementation. so, if them exist at the same time ,the global implementation will be used.

Suggestion

1. you should usually define the default implementation for one interface, not the global one.
2. when you want to realize a new implementation for the interface, you can define the new implementation as global.
3. when the global implementation is achieved and fully tested, delete the default implementation, and change the new global implementation to the default implementation.
