toolview.IVolatileStore interface

The volatile store that i2 Notebook makes available to tool views.

Signature:

interface IVolatileStore 

Introduced: version 1.0

Remarks

When a tool view goes from being docked to undocked (or vice versa), or from being open to closed, its window is unloaded and any information associated with the window is lost.

The purpose of the volatile store is to let you retain information when the window is unloaded, and then restore it when the window is re-created. The store is "volatile" because its contents are lost when the i2 Notebook application window is closed or reloaded.
