// CRefresher

|
|
// The refresher maintains an object and an enumerator cache. When an enumerator is added to the refrehser
|
|
// it is added to the enumerator cache, and the index of the array is passed back as a unique ID.
|
|
// The refresher creates a cache of all instances during its initialization. When an object
|
|
// is added to the refresher, a mapping to the object is created between the unique ID and the index of
|
|
// the object in the cache. This allows the objects to be reused and facilitates the management of objects
|
|
// that have been added multiple times.
