Detailed Description

ISIS DLM File repository This class follows the classic Singleton pattern by the Gang Of Four (GOF). A discussion of this technique can be studied in their book Design Patterns: Elements of Reusable Object-Oriented Software.

This particular class serves as a holding tank for ISIS cube files and PVL like files. Although ISIS files have a PVL label, I distinguish between the two because they require different management schemes.

Isis labels are managed in real time in that all label manipulation is immediate. Any change that results in a modification of the the label content is immediately reflected in the file label (?).

PVL labels are contained within this repository until they are explicitly closed by the user or the program terminates and a purging of the repository is performed.

The unique access method This method is the one and only one method that provides access to this object. It maintains an instance of itself by checking to see if the _instance variable is defined. If not it creates an instance of itself and returns a pointer.

Note that the destructor is private to disallow user to delete it. This is forcibly maintained by the compiler.
