Handling privates and all other constructors of an object
For constructors handling we are going to use Constructors component. Constructors component uses to cache all constructors and all method handles for faster access.
import static org.burningwave.core.assembler.StaticComponentContainer.Constructors;
import org.burningwave.core.classes.MemoryClassLoader;
public class ConstructorsHandler {
public static void execute() {
//Invoking constructor by using reflection
MemoryClassLoader classLoader = Constructors.newInstanceOf(MemoryClassLoader.class, Thread.currentThread().getContextClassLoader());
//Invoking constructor with a null parameter value by using MethodHandle
classLoader = Constructors.newInstanceDirectOf(MemoryClassLoader.class, null);
}
public static void main(String[] args) {
execute();
}
}ClassFactory
