Basic Concepts

DepIn is a dependency Injection tool that written in java

Simple usage

The simples usage of this library is:

DefaultClass defaultClass = InstanceBuilder.init(DefaultClass.class).build();

This way, we create a defaultClass instance with all dependencies. Note that we create dependencies of this instance from scratch.

If we want to pass spesific argument to instance's constructor method, we may use:

We use withArgs(Object... args) chain method for injecting arguments with constructor

ExampleClass ec = InstanceBuilder
        .init(ExampleClass.class)
        .withArgs("ConstructorStringArg")
        .build();

There is other ways to instantiate classes. For example, setters. We can simply inject dependencies with setters like this:

Firstly, we need a map to store and match setter and their arguments

Map<String,Object> setterMap;

And then, we need to describe our setter methods and their arguments

setterMap.put("setSecretString","Selam");

Finally, we can use our map in withSetters(Map<String,Object> setters) chain method to create instance

ExampleClass ec = InstanceBuilder
        .init(ExampleClass.class)
        .withSetters(setterMap)
        .build();

We can similarly inject our dependencies directly with fields. We just use withFields(Map<String,Object> setters) chain method. This is inject the spesific fields that named in map with the corresponding object arguments
