TObjectArray class
Implements an array of items with their associated objects.
Declaration
TObjectArray<TItem,TObj> = classDescription
TObjectArray is a generic type used to implement an array of items
and their associated objects. TObjectArray allows the association to be
defined using the TItem and TObj class types. Internally, it uses a list of
records with pointers to the
Items and
Objects stored
in the class. Properties and methods are provided to maintain and access the
entries in the class instance, and the allocated storage for the array type.
