Handling privates and all other fields of an object · burningwave/core Wiki · GitHub

For fields handling we are going to use Fields component; Fields component uses to cache all fields for faster access.

import java.lang.reflect.Field;
import java.util.Collection;
import java.util.List;
import java.util.Map;

import org.burningwave.core.classes.FieldCriteria;

public class FieldsHandler {
    
    public static void execute() {
        ClassLoader classLoader = Thread.currentThread().getContextClassLoader();
        //Fast access by memory address
        Collection<Class<?>> loadedClasses = Fields.getDirect(classLoader, "classes");
        //Access by Reflection
        loadedClasses = Fields.get(classLoader, "classes");
        
        //Get all field values of an object through memory address access
        Map<Field, ?> values = Fields.getAllDirect(classLoader);
        //Get all field values of an object through reflection access
        values = Fields.getAll(classLoader);
        
        Object obj = new Object() {
            volatile List<Object> objectValue;
            volatile int intValue = 1;
            volatile long longValue = 2l;
            volatile float floatValue = 3f;

            FieldCriteria.forEntireClassHierarchy().allThoseThatMatch(field -> {

            }),
