00035 // Description: This file contains the class definition for 
00036 // ArrayOfTaggedObjects. ArrayOfTaggedObjects is a storage class. The class 
00037 // is responsible for holding and providing access to objects of type 
00038 // TaggedObject. The data structure used to hold the objects is a simple 
00039 // array of pointers. As a one dimensional array is used certain ideas are tried 
00040 // to improve performance: (1) if the array needs to be larger to hold more 
00041 // components, the array size is doubled and (2) when adding/retrieving components,
00042 // the array location given by the components tag is first checked. 
00043 //
