DictionaryBase | serializable | System.Collections (mscorlib.dll) | abstract class | This abstract base class is used to implement specialized dictionary style collections. Classes derived from DictionaryBase allow for strongly typed key and value pairs. A set of protected instance methods is defined to be overridden by derived classes. These methods allow a class to specify customized processes when functions are performed on the derived object. For example, OnSet( ) lets you perform a function before you set a new element in the dictionary, while OnSetComplete( ) lets you perform a function after a value is set. public abstract class DictionaryBase : IDictionary, ICollection, IEnumerable { // Protected Constructors protected DictionaryBase ( ); // Public Instance Properties public int Count {get; } // implements ICollection // Protected Instance Properties protected IDictionary Dictionary {get; } protected Hashtable InnerHashtable {get; } // Public Instance Methods public void Clear ( ); // implements IDictionary public void CopyTo (Array array , int index ); // implements ICollection public IDictionaryEnumerator GetEnumerator ( ); // implements IDictionary // Protected Instance Methods protected virtual void OnClear ( ); protected virtual void OnClearComplete ( ); protected virtual object OnGet (object key , object currentValue ); protected virtual void OnInsert (object key , object value ); protected virtual void OnInsertComplete (object key , object value ); protected virtual void OnRemove (object key , object value ); protected virtual void OnRemoveComplete (object key , object value ); protected virtual void OnSet (object key , object oldValue , object newValue ); protected virtual void OnSetComplete (object key , object oldValue , object newValue ); protected virtual void OnValidate (object key , object value ); } Subclasses System.Diagnostics.{InstanceDataCollection , InstanceDataCollectionCollection} |
