DictionaryBase
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.
