A cleaner way to write Java code, through a pipeline
Pipe4j creates a new and cleaner way for developers to write code through a pipeline
- The ability to chain all method calls in a single path
- Receive the result of the last operation as the input for the next one
- Don't let Exceptions make your code looks bad
- Even Checked Exceptions 😜
- Very simple and easy to use
import io.pipe4j.Pipe4j;
import static io.pipe4j.SilentThrow.silent;
public class Main {
public static void main(String[] args) {
// Receives an String and returns an Integer
Pipe4j<String, Integer> pipe = value -> Integer.valueOf(value);
Integer result = pipe
.pipe(i -> i.doubleValue()) // in: Integer, out: Double
.pipe(d -> d + 2.0) // in: Double, out: Double
// handle checked Exception with no try/catch or by adding "throws" to the method signature
// and returns a fallback value (99)
.pipe(d -> silent(() -> toInt(d), (e) -> 99)) // in: Double, out: Integer
.apply("10"); // the argument for the first step of the pipeline
System.out.println("Result: " + result); // => Result: 99 (or 12, if toInt() don't throw any exception
}
public static Integer toInt(Double value) throws Exception {
throw new Exception("Something went wrong");
}
}
