Example usage

Consider an Activity you would like to start, ExampleActivity:

public class ExampleActivity extends AppCompatActivity {

ExampleActivity may have a few parameters it receives from another Activity:

private int numberToDisplay // This param is required for ExampleActivity to start successfully!
private String stringToDisplay
private DataModel dataModel; // Parcelable or Serializable

With Piri, you can generate an Intent builder for ExampleActivity, and it only requires a few annotations.

public class ExampleActivity extends AppCompatActivity {    
    @PiriParam(required = true)
    protected int numberToDisplay;
    
    @PiriParam
    protected String stringToDisplay;
    
    @PiriParam
    protected DataModel dataModel;
    
    ...

Okay cool! But how do we use it? When you build your project, a class called ExampleActivityIntentCreator will be generated:

// number gets created as a constructor param due to being required
Intent intent = new ExampleActivityIntentCreator(context, number)
        .stringToDisplay(string)
        .dataModel(dataModel)
        .addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK, Intent.FLAG_ACTIVITY_NEW_TASK)
        .create();
startActivity(intent);

Easy! You can then retrieve your data when ExampleActivity is started with Piri.bind():

@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_example);
    Piri.bind(this)
    
    // Defined PiriParam variables are set for you
    ...
