Constructor Summary public   KeyedObjects()      Creates a new collection (initially empty). Method Summary public  void addObject(Comparable key, Object object)      Adds a new object to the collection, or overwrites an existing object. public  Object clone()      Returns a clone of this object. public  boolean equals(Object o)      Tests if this object is equal to another. Parameters:   o - the other object. public  int getIndex(Comparable key)      Returns the index for a given key. Parameters:   key - the key. public  int getItemCount()      Returns the number of items (values) in the collection. public  Comparable getKey(int index)      Returns a key. Parameters:   index - the item index (zero-based). public  List getKeys()      Returns the keys. public  Object getObject(int item)      Returns an object. Parameters:   item - the item index (zero-based). public  Object getObject(Comparable key)      Returns the object for a given key. public  void removeValue(int index)      Removes a value from the collection. public  void removeValue(Comparable key)      Removes a value from the collection. public  void setObject(Comparable key, Object object)      Replaces an existing object, or adds a new object to the collection. Constructor Detail KeyedObjects public KeyedObjects()(Code) Creates a new collection (initially empty). Method Detail addObject public void addObject(Comparable key, Object object)(Code) Adds a new object to the collection, or overwrites an existing object. This is the same as the KeyedObjects.setObject(Comparable,Object) method. Parameters:   key - the key. Parameters:   object - the object. clone public Object clone() throws CloneNotSupportedException(Code) Returns a clone of this object. A clone. throws:   CloneNotSupportedException - if there is a problem cloning. equals public boolean equals(Object o)(Code) Tests if this object is equal to another. Parameters:   o - the other object. A boolean. getIndex public int getIndex(Comparable key)(Code) Returns the index for a given key. Parameters:   key - the key. The index, or -1 if the key is unrecognised. getItemCount public int getItemCount()(Code) Returns the number of items (values) in the collection. The item count. getKey public Comparable getKey(int index)(Code) Returns a key. Parameters:   index - the item index (zero-based). The row key. throws:   IndexOutOfBoundsException - if index is out of bounds. getKeys public List getKeys()(Code) Returns the keys. The keys (never null). getObject public Object getObject(int item)(Code) Returns an object. Parameters:   item - the item index (zero-based). The object (null if the index is out of range). getObject public Object getObject(Comparable key)(Code) Returns the object for a given key. If the key is not recognised, the method should return null. Parameters:   key - the key. The object (possibly null). removeValue public void removeValue(int index)(Code) Removes a value from the collection. Parameters:   index - the index of the item to remove. removeValue public void removeValue(Comparable key)(Code) Removes a value from the collection. Parameters:   key - the key of the item to remove. setObject public void setObject(Comparable key, Object object)(Code) Replaces an existing object, or adds a new object to the collection. This is the same as the KeyedObjects.addObject(Comparable,Object) method. Parameters:   key - the key. Parameters:   object - the object.
