I want to set a debug breakpoint in IntelliJ Idea that is only active, if another previous breakpoint was activated. For example i have a breakpoint B1 on line

    An alternate programmatic approach to debug specific classes when some condition in some class is met.

    /*
 * Breakpoint helper, stops based on a shared state
 *  STOP variable
 *
 * Everything in here should be chainable
 *  to allow adding to breakpoints
 */
public final class DEBUG {

/*
 * global state controlling if we should
 *   stop anywhere
 */
public static volatile boolean STOP = false;

public static volatile List REFS = new ArrayList<>();

/**
 * add object references when conditions meet
 * for debugging later
 */
public static boolean ADD_REF(Object obj) {
    return ADD_REF(obj, () -> true);
}

public static boolean ADD_REF(Object obj, Supplier condition) {
    if (condition.get()) {
        REFS.add(obj);
        return true;
    }
    return false;
}

/*
 * STOPs on meeting condition
 *  also RETURNS if we should STOP
 *
 * This should be set when a main condition is satisfied
 *      and can be done as part of a breakpoint as well
 */
public static boolean STOP(Supplier condition) {
    if (condition.get()) {
        STOP = true;
        return true;
    }
    return false;
}

public static boolean STOP() {
    return STOP(() -> true);
}



    Where you want a condition to set the breakpoint

    


    Where you want to stop based on a condition
