      • maybeWarnAboutAnonymousValue

        protected void maybeWarnAboutAnonymousValue​(T t)
        Looks for situations where clients may lose the values added to this class. This most often happens when a client adds an anonymous, local listener to an object that is using a WeakSet to store its listeners. Our policy is to implement listeners at the class field level so that they will not be flagged by this method.
        Parameters:
        t - The object to check

      • add

        public abstract void add​(T t)

      • remove

        public abstract void remove​(T t)
        Remove the given object from the data structure
        Parameters:
        t - the object to remove

      • contains

        public abstract boolean contains​(T t)
        Returns true if the given object is in this data structure
        Returns:
        true if the given object is in this data structure

      • clear

        public abstract void clear()
        Remove all elements from this data structure

      • size
