Method Removed

A method is removed from its owning class.

Example

Method add() is removed from the class Math in the library project.

public interface Math {
- int power(int base, int power);

}

Broken Uses

Hereafter, we list the broken uses that are currently detected by Maracas.

• 1. Invocations to the now-removed method
• 2. Methods overriding the now-removed method

1. Invocations to the now-removed method

Example

Method displayPower()—defined in the Calculator class in a client project—invokes an implementation of the now-removed method. Then, a broken use is reported pointing to the method invocation expression.

public class Calculator {
  public void displayPower(int base, int power) {
    Math math = new MathImpl();
    // Broken use reported here
    int result = math.power(base, power);
    System.out.println(result);
  }

}

2. Methods overriding the now-removed method

Example

The MathImpl class in a client project overrides the now-removed method. Then, a broken use is reported pointing to the client method declaration.

public class MathImpl implements Math {
  // Broken use reported here
  @Override
  public int power(int base, int power) {
    int result = 1;
    for (int i = 0; i < power; i++)
      result = result * base;

    return result;
  }

}
