Constructor Detail Singleton public Singleton()(Code) Creates a initially empty singleton. Method Detail add public boolean add(Object object)(Code) Adds the specified element to this set if it is not already present. If this set already contains an other element, an exception is thrown. throws:   NullPointerException - if the argument is null. throws:   IllegalArgumentException - if this set already contains an other element. clear public void clear()(Code) Removes the element from this singleton. contains public boolean contains(Object object)(Code) Returns true if this singleton contains the specified element. get public Object get() throws NoSuchElementException(Code) Returns the element in this singleton. The singleton element (never null). throws:   NoSuchElementException - if this singleton is empty. isEmpty public boolean isEmpty()(Code) Returns true if this singleton contains no elements. iterator public Iterator iterator()(Code) Returns an iterator over the element of this singleton. remove public boolean remove(Object object)(Code) Removes the specified element from this singleton, if it is present. size public int size()(Code) Returns 1 if this singleton contains an element, or 0 otherwise.
