If the defined element size is exceeded, the firstly stored element gets removed. author:    Thomas Morgner Constructor Summary public   KeyedQueue()      Creates a KeyedQueue with an initial limit of 10 items. public   KeyedQueue(int limit)      Creates a KeyedQueue with an initial limit if limit items. Method Summary public  void clear()      Removes all elements in the queue. public  Object clone()      Clones the queue. public  Object get(Object key)      Queries the queue for the value stored under the given key. Parameters:   key - the key. public  int getLimit()      Returns the maximum number of elements in the queue. public  void put(Object key, Object ob)      Adds a new key/value pair to the queue. public  void remove(Object key)      Removes the entry stored under the given key. public  void removeLast()      Removes the last element in the queue. public  void setLimit(int limit)      Defines the maximal number of elements in the queue. Constructor Detail KeyedQueue public KeyedQueue()(Code) Creates a KeyedQueue with an initial limit of 10 items. KeyedQueue public KeyedQueue(int limit)(Code) Creates a KeyedQueue with an initial limit if limit items. Parameters:   limit - the maximum number of items. Method Detail clear public void clear()(Code) Removes all elements in the queue. clone public Object clone() throws CloneNotSupportedException(Code) Clones the queue. a clone. throws:   CloneNotSupportedException - this should never happen. get public Object get(Object key)(Code) Queries the queue for the value stored under the given key. Parameters:   key - the key. the value. getLimit public int getLimit()(Code) Returns the maximum number of elements in the queue. the maximum number of elements in the queue. put public void put(Object key, Object ob)(Code) Adds a new key/value pair to the queue. If the pair is already contained in the list, it is moved to the first position so that is gets removed last. Parameters:   key - the key. Parameters:   ob - the value. remove public void remove(Object key)(Code) Removes the entry stored under the given key. Parameters:   key - the key. removeLast public void removeLast()(Code) Removes the last element in the queue. setLimit public void setLimit(int limit)(Code) Defines the maximal number of elements in the queue. Parameters:   limit - the maximum number of items.
